during passive transport what are the concentration of substances on either side of the membrane trying to reach

Answers

Answer 1

Answer:

During passive transport, the concentration of substances on either side of the membrane are trying to reach equilibrium.

Explanation:

Passive transport can be described as the movement of molecules from a region of higher concentration to a region of lower concentration along a concentration gradient. As the molecule are higher at one side and lower on the other side, the molecules move so that there can be equal  number of molecules on each side so that equilibrium can be reached and maintained.

Which of the following explains why antibiotics will not work against a viral infection?
A). Viruses replicate at such an accelerated rate that antibiotics are unable to control colonization and growth.
B). Viruses create highly resistant endospores that preserve their genetic material against antibiotics.
C). Viruses are not cellular and do not contain the lipid and protein markers targeted by antibiotics.
D). Viruses exchange genetic material with nearby bacteria that have become resistant to antibiotics.

Answers

Answer:

I think its C. Viruses are not cellular and do not contain the lipid and protein markers targeted by antibiotics.

Explanation:

Viruses are not considering living and are different to bacteria; they have a different structure and a different way of surviving. Viruses don’t have cell walls that can be attacked by antibiotics. Antibiotics basically attack the cell wall of bacteria or attach to markers on cell wall of bacteria to trigger some deadly reactions in bacteria which causes them to die. Viruses don't have cell wall instead they are surrounded by a protective protein coat.

Unlike bacteria, which attack your body’s cells from the outside, viruses actually move into, live in and make copies of themselves in your body’s cells.  Viruses can't reproduce on their own, like bacteria do, instead they attach themselves to healthy cells and reprogram those cells to make new viruses.

Therefore, I strongly believe it's C.

why bother with the control plants if they are not going to be sprayed with gibberellic acid

Answers

Gibberellic acid is a natural growth hormone present in plants which helps plants to control growth naturally. Spraying additional gibberellic acid helps to stimulate plant growth. So even if it is not sprayed externally, the natural acid present in the plants still controls the growth.

Explanation:

Gibberellic acid (gibberellin) is naturally found in growing apical regions like the shoots, new young leaves, flowers. In the shoots, it helps to increase the inter-node length and thereby increases elongation of a plant through apical growth. They control the growth by acting as chemical messengers.

Farmers usually spray gibberellic acid during seed germination to accelerate plant growth, budding processes, increase foliage and flowering.  Spraying farms with bioactive gibberellins have led to a huge increase in plant growth leading to the green revolution.


Which setting would allow you to observe a specimen with the highest possible magnification?​

Answers

The setting which would allow us to observe a specimen with the highest possible magnification is the Objective 10x Ocular 10x.

Explanation:

To observe a specimen with the highest possible magnification is the magnification needed to be the maximum. To gain such a magnification, magnification power of objective and magnification power of ocular or eye lens will be required together at max being the product. Because,

Magnification of object = magnification by ocular lens x magnification by objective lens.

Thereby, among the option, when the magnification power of objective lens is 10X and that of ocular lens is 10X, together will produce a magnification of 100X.

Final answer:

The highest possible magnification to observe a specimen can be achieved using the oil immersion objective lens with a magnification of 1000X and a resolution of 0.2°m.

Explanation:

To observe a specimen with the highest possible magnification, you should use the oil immersion objective lens on a light microscope. This lens can achieve a total magnification of 1000X, which means objects appear 1000 times larger than they are. A resolution of 0.2°m is the practical limit due to the diffraction of light waves, but the oil immersion objective allows for the observation of small structures such as bacteria, which are difficult to see clearly without this enhancement.

When preparing to use the oil immersion lens, you should first sequentially increase the objective magnification up to 40x. Once you focus on the target area, you can then swing the objective halfway to 100x magnification and add a drop of immersion oil to the area of analysis before finally focusing the specimen at the full 1000x magnification using the oil immersion objective.

Methionine (start codon) , leucine, methionine, arginine, aspartic acid, glycine, glycine, leucine, histidine, stop codon

Three types of RNA that takes part in the translation are:

mRNA: It is formed by the process of transcription. The DNA strand is copied as mRNA with help of RNA Polymerase. The mRNA strand is single- stranded and consists of codons which code for amino acids for the protein synthesis. Not full sequence of mRNA codes for amino acid chain there are non-coding regions called introns which are removed during splicing and only exons code for the amino acid sequences.

tRNA: It brings the correct amino acid to the growing polypeptide chain by reading the codons from the mRNA. It has anticodon which helps in bringing the correct amino acid coding to mRNA sequence.

rRNA: rRna plus protein and ribosome makes up rRNA. The ribosomes are called protein factory,  because growing polypeptide chain is formed here. They are responsible for reading the correct amino acid bonding to form polypeptide. They are having two subunits smaller and bigger depending on their sedimentation rate by centrifugation.

In eukaryote,s protein synthesis occurs in the ribosomes which are present in the cytoplasm of the cell.

B. All the three nucleotides that code for amino acid are important because any base difference in amino acid will change the protein formed due to amino acid difference.

What cavities are in the head, but are not included within the major cavities?

Answers

Answer:

Dorsal cavity

I hope it is correct for you!!!!!!!!!

Final answer:

The paranasal sinuses are cavities in the head that are separate from the major cavities like the cranial and spinal cavities.

Explanation:

The cavities in the head that are not included within the major cavities are the paranasal sinuses. These are air-filled spaces located within the bones of the skull and face, including the frontal, ethmoid, sphenoid, and maxillary sinuses. The paranasal sinuses are lined with mucous membranes and help to warm and humidify the air we breathe.



Some functions of the paranasal sinuses include reducing the weight of the skull, resonating the voice, and providing a buffer zone for facial trauma.



Therefore, the paranasal sinuses are cavities within the head that are separate from the major cavities such as the cranial and spinal cavities.

Which term best describes the temperature and weather conditions of an organism's environment

Answers

Answer:

Abiotic factors can be described as the non-living components of an ecosystem. Biotic factors can be described as the living components of an ecosystem.

Abiotic factors include all the non- living components such as the weather, climate, temperature, soil, water of an area.

Biotic components include all the living organisms like the plants, animals, microorganisms of an ecosystem.

Hence, abiotic factors best describe the temperature and weather conditions of an organism's environment.

Final answer:

The term that describes the temperature and weather conditions of an organism's environment is 'climate'. Climate and temperature significantly affect the physiology, metabolism, and survival of organisms, leading to various adaptations. Animals may be ectotherms, whose body temperature varies with the environment, or endotherms, who maintain a constant body temperature.

Explanation:

Climate is the word that best conveys how hot or cold an environment is for an organism. The long-term, dependable atmospheric conditions of a particular region are referred to as the climate. It may have a big effect on how organisms behave and survive. A biome's climate is identified by its regular seasonal temperature and rainfall ranges. Unlike weather, which describes the state of the atmosphere over short time frames, climate represents patterns over longer periods.

Temperature, an aspect of climate, is critical to organisms as it affects their physiology and metabolic functions. Many living organisms can only survive within a specific range of temperatures, mainly due to limitations in enzyme activity and metabolic processes. Some organisms have adapted to tolerate significant fluctuations in temperature. For instance, certain animals can hibernate, going into a state of lowered metabolism and body temperature to survive in cold conditions. Similarly, some bacteria, referred to as extremophiles, can survive in extremely high-temperature conditions such as those found in geysers.

Moreover, animals can be divided into ectotherms and endotherms based on how they deal with environmental temperatures. Ectotherms, such as reptiles, do not internally regulate their body temperature, which varies with the environmental temperature. Endotherms, like mammals, use internal physiological mechanisms to maintain a fairly constant body temperature, regardless of environmental temperatures.

Deletion can happen as a gene mutation or as a chromosomal mutation. What is the difference?

Answers

Answer:

Chromosomal mutations: produce changes in the number or structure of chromosomes (they include deletions, duplications, inversions, and translocations). Deletion: involves the loss of all or part of a chromosome.

Final answer:

Deletions describe the loss of a chromosome segment, often resulting in many genes missing, and represent a chromosomal mutation, while gene mutations refer to smaller-scale alterations affecting specific gene sequences within the DNA.

Explanation:

The difference between a gene mutation and a chromosomal mutation lies in the scale of the genetic alteration. A gene mutation, also known as a point mutation, involves a change in a single base pair or a few nucleotides within the DNA sequence, affecting a single gene. This is considered to be a micro-level alteration. On the other hand, a chromosomal mutation results in changes at the chromosome level, such as deletions where a large segment of a chromosome is lost, which may involve several to hundreds of genes, or duplications, where a section of the chromosome is repeated.

Chromosomal mutations can have significant consequences such as developmental delays, as illustrated by trisomy 21, which causes Down Syndrome. Other examples include inversions, where a segment of a chromosome breaks off, flips, and reattaches, and translocations, where segments between non-homologous chromosomes are exchanged. These large-scale alterations often impact multiple genes and can influence the overall structure and function of the chromosomes, leading to more profound effects on an organism compared to most gene mutations.

In guinea pigs, the allele for a rough coat (R) is dominant over the allele for a smooth coat (r). A heterozygous guinea pig (Rr) and a homozygous recessive guinea pig (rr) reproduce and have 10 offspring. Explain how all 10 offspring can have smooth coats.

Answers

All the 10 offsprings have recessive smooth coats because all the progeny are formed by recessive r allele and resulted is smooth coat. It was because one of the parents was heterozygous.

Explanation:

Rough coat R is dominant over the allele for smooth coat r

Heterozygous guinea pig Rr is crossed with homozygous recessive guinea pig rr

So from the Punette square

      r     r

R  Rr    Rr

r   rr    rr

There are chances of occurrence of 50 % each of heterozygous rough and dominant recessive smooth coats.

From the result obtained in actual, all the offspring have smooth coats because all of these offsprings have receive recessive allele from their parent and have become homozygous recessive.

Final answer:

Inheritance of smooth coats in all offspring from a heterozygous (Rr) and homozygous recessive (rr) guinea pig mating is due to each offspring inheriting the recessive 'r' allele from both parents, which is statistically improbable but possible.

Explanation:

In guinea pigs, the allele for a rough coat (R) is dominant over the allele for a smooth coat (r). When a heterozygous guinea pig (Rr) reproduces with a homozygous recessive guinea pig (rr), their offspring can inherit one allele from each parent. The offspring could either be heterozygous (Rr) with a rough coat or homozygous recessive (rr) with a smooth coat. If all 10 offspring have smooth coats, it is likely because each offspring randomly received the recessive 'r' allele from the heterozygous parent and the recessive 'r' allele from the homozygous recessive parent, resulting in a genotype of rr, which expresses the smooth coat phenotype.

A heterozygous individual has a 50/50 chance of passing on the dominant or recessive allele. In this case, all offspring receiving the 'r' allele from the heterozygous parent would have smooth coats, as the 'rr' genotype expresses the recessive phenotype. However, it is statistically improbable for all offspring to inherit the same allele unless other factors are influencing inheritance or a very small sample size creates a misleading result.

Explanation:

1. Number of turkey oak seedlings in the burned forest (given): 10 seedlings

2. Number of turkey oak seedings in the unburned forest (given): 90 seedings

3. To find the total number of turkey seedings you must add the seedings found in the burned forest and the seedings found in the unburned forest:

Total number of turkey seedings: 10 seedings + 90 seedings = 100 seedings.

4. If the seedlings were randomly distributed in the two forests, then the numbers of seedlings in each forest would be the same (given)

How many seedlings would you expect in each forest if they were randomly

Great thanks in a light-year told you about the distance to stars or galaxies are away from each other Thomas disagrees as he thinks it is about the mount of time you would take to travel between two places in the galaxy explain what you think their ideas about light years

Answers

Answer:year lights

Explanation:

A light-year measures the distance light travels in one Earth year, which is about 9.5 trillion kilometers. Grace is correct in her definition, while Thomas is incorrect, as a light-year is not a measure of travel time but rather of distance.

Grace's understanding of a light-year being a measure of distance between two stars or galaxies is correct. A light-year is indeed the distance that light travels in a vacuum in one Earth year. Since light travels at about 300,000 kilometers per second, a light-year equates to approximately 9.5 trillion kilometers. This measurement is used by astronomers to express astronomical distances that are beyond the scale of our Solar System, making it a crucial concept in understanding the vastness of space.

On the other hand, Thomas is mistaken. A light-year is not a measure of the time it would take a human to travel between two places in the galaxy; rather, it's a measure of how far light can travel in a year. When we look at a star that is, say, 4 light-years away, we are seeing it as it was 4 years ago because that's how long it has taken the light to reach us.
