Answer:

C

. The mass of carbon in the products is greater than the mass of carbon in the reactants.

Explanation:

i did it

The result that could NOT occur according to the law of conservation of matter is the mass of carbon in the products being greater than the mass of carbon in the reactants. Option C is correct.

Lisa is investigating a chemical reaction involving carbon compounds. According to scientific laws about chemical reactions, matter, and energy, the result that could NOT occur is: The mass of carbon in the products is greater than the mass of carbon in the reactants.

This violates the law of conservation of matter, which states that there is no detectable change in the total amount of matter during a chemical change. The other options (A, B, D, and E) are all possible outcomes of chemical reactions. Reactions can release or absorb energy, and the presence of a catalyst such as a protein can indeed increase the rate of a reaction without changing the amount of matter.

Hence, C. is the correct option.

Answer: Haploid cells have 23 chromosomes while diploid cells have 46 (23 pairs) chromosomes

Explanation: Haploid cells are produced in a type of cell division called meiosis. In meiosis, parent cells undergo two cell divisions to produce four daughter cells with half the number of chromosomes in the parent cell. Diploid cells are produced by a type of cell division known as mitosis. In mitosis, parent cells undergo one cell division to produce two identical daughter cells that have the same number of chromosomes as the parent cell. Gametes undergo meiosis while somatic cells undergo mitosis.

Answer: The complementary strand is TCC- GAT - TTG

Explanation: During DNA replication, each strand of the DNA serves as a template for the synthesis of a new strand, thereby producing two new DNA molecules, each with one new strand and one old strand. A template is a DNA strand that would allow nucleotide molecules to be lined up in a specific order and be joined to create another DNA with a unique sequence. This results in creation of a double stranded DNA in which each strand is complementary to the other. In nucleotide base pairing, Guanine pairs with Cytosine while Thymine pairs with Adenine.

Carl and Abby are discussing what they have learned in class about electricity and magnetism. Carl tells Abby that an electric current running along a wire can be used to produce a magnetic force. Abby, on the other hand, tells Carl that moving electrons through a magnetic field can produce an electric current. Which of the students is/are correct? A. Only Abby is correct. B. Both Carl and Abby are correct. C. Neither student is correct. D. Only Carl is correct.

Both Carl and Abby are correct.

Option B

The electrons that move through a magnetic field are moving in a circular motion. This is because the electric field and magnetic fields are perpendicular to each other. And the electrons move maintaining the Fleming's Left Hand Rule. And by current, we actually mean moving electrons. So electrons moving in magnetic field can produce current. So Abby is correct.

According to Carl, the electric current moving through a wire can produce magnetic field. This is the magnetic effect of current. The magnetic field produced by the wire is perpendicular to the wire maintaining Fleming's Left Hand Rule and its strength depends on current strength and distance from wire. So both Carl and Abby are correct.

3. genotype is round seed

phenotype is Rr

4. genotype is grey fur

phenotype are WW and Ww

5. genotype is short

phenotype is tt

1. genotype is high metabolism

phenotype are HH and Hh

Explanation:

The dominant trait is the capital letter and the reccessive is the lowercase letter.

To do a punnet square you bring down each letter say like problem 1, you bring down capital D down and little d down to each of the 2 squares below them, then you drag the sides to the right of the two squares and you get DD for the first square, then Dd, then below Dd, then next to it DD.

Phenotype is a organism's actual appearence.

Genotype is a gene combination. The gene combination that determines the phenotype

Answer: 3) Possible phenotypes is Rr only. All offsprings have Rr genotype.

Possible phenotypes: All the offsprings have round seed.

4). Possible genotypes are WW, Ww and ww.

Possible phenotypes: Three offsprings have white fur while one offspring has black fur.

5). Possible genotypes is tt only, all the offsprings have tt genotype.

Possible phenotypes: All the offsprings are short

I) Possible genotypes are HH and Hh.

Possible phenotypes: All the offsprings have high metabolism.

Explanation: Dominant trait is able to express itself in the presence of a recessive trait. A recessive trait is not able to express itself in the presence of a dominant trait.

Genotype is the gene makes up of an organism while phenotype is the physical manifestation of the genetic make up. Phenotype is simply the outward appearance of an organism which are usually controlled by the genes.

Penguins are the rarest commodity of Antarctica. The paths they follow, carved by thousands of tiny footsteps, lead to Antarctica's rarest commodity.

Explanation:

The treaty sets aside Antarctica as a logical protect, sets up opportunity of logical examination, and bans military movement on the landmass. The bargain was the primary arms control understanding built up during the Cold War.

There are no regions in Antarctica by the Antarctic Treaty so you can travel anyplace on the landmass. In any case, by a similar settlement, there are various rules that all guests are required to follow. For instance, to regard logical research.

Answer:

What Is DNA's Role in Inheritance? DNA is the genetic information used to make proteins, and it contains the hereditary traits of organisms. There are two types of DNA: mitochondrial DNA, which you can only get from your mother, and nuclear DNA, which is a combination of both your ancestors' DNA.

DNA is the molecule of inheritance because it contains the genetic information passed from parent to offspring. Its structure allows for replication and transmission of this information. DNA is composed of four nucleotides that can be combined in different sequences to encode instructions for living organisms.

Final answer:

The independent variable is what the researcher manipulates in an experiment to see its effect on the dependent variable, which is the outcome being measured.

Explanation:

The independent variable is the factor in an experimental study that is manipulated or controlled by the researcher. Its purpose is to determine if it causes any change in the dependent variable, which is the factor being measured or observed. While conducting an experiment, the researcher changes the independent variable in a controlled way and then observes any changes that occur in the dependent variable as a result. A key aspect of a well-designed study is ensuring that the independent variable is the only significant factor altered between the experimental and control groups so that any observed effects can be attributed to it.

Examples

For instance, if scientists are studying the effect of different fertilizers on plant growth, the type of fertilizer is the independent variable because it's what the scientist changes. The growth of the plants, measured perhaps in height or biomass, is the dependent variable because it's what is being affected and measured.

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.

Marine pollution is the cause for dolphins and whales to strand on beaches.

Explanation:

Mother genotype is IAi (hetero-zygous) as the mother is a dominant trait.

Man is Rh negative and O type blood group its genotype is OrOr

Mother is A positive so her genotype would be either IAIA or IAi

Also A blood group is dominant over O blood group.

It is given:

two children are A POSITIVE

One child is A negative

So the mother must have been hetero-zygous with genotype IAi as one of children would received it from mother as it is a dominant trait.

Punnete square shows

      AI   Ai

i     AIi   Aii

i     AIi   Aii    

50 percent chances of A negative child is there.

The mother's most likely genotype is heterozygous for both the ABO blood type gene (A and O alleles) and the Rh factor gene (Rh positive and Rh negative alleles), which is genotype IAiRr.

The question involves deciphering the mother's genotype based on the blood types and Rh factors of her children, considering that blood type and Rh factor are not linked genes and have their distinct inheritance patterns.

Given that the father's phenotype is O negative (ii, rr), and two of the children have A positive blood type, the mother must be heterozygous for both the ABO and Rh factor genes. The presence of a type A, Rh negative child, confirms the mother has at least one copy of the recessive Rh negative allele (r) and one recessive O allele (i).

Considering the inheritance possibilities, the mother's most probable genotype would be IAiRr, which is option B) IAiRr. This allows the mother to have children with type A blood (whether Rh positive or Rh negative) as observed and rules out her having two dominant Rh positive alleles or two dominant A alleles, which would make it impossible for her to have an Rh negative or type O child.

Yes, the given activity is a correct example which describes phototropism

Phototropism is an adaptation or a survival mechanism undertaken by some plants to receive maximum sunlight in order to prepare more food and energy through photosynthesis.  

Explanation:

Phototropism takes place through receptor proteins called phototropins which act as blue light photoreceptors.

Phototropic activity:

Phototropism can best be observed by planting few plants including phototropic plants in pots and keeping them near the window to receive sunlight.

The natural bending of phototropic plants towards the window denotes their inclination towards sunlight.

The growth of sunflower plants facing towards the sun and blooming of lotus flower under sunlight are all examples of phototropism.

Other plants which are phototropic are Phalaenopsis, azuki beans, fungus of Phycomyces species, etc.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Explanation:

We are looking for a parent cell that gives rise to daughter cells with identical genetic information.

In simpler words, we are looking for something that makes 'clones' of itself.

In this statement (second option), the parent and daughters are all feline skeletal muscle cells.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Other incorrect choices: (All having to do with reproduction).

A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.

This situation has two parents, each with a different trait. The child takes one of the parent's trait. The parents did not make a 'clone' of themselves.

A human sperm fuses with a human egg cell, resulting in the development of a new human.

The parents don't make 'clones' of themselves. The sperm did not make more sperm. The egg did not make more egg cells.

A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.

The offspring plant only took the trait from one of it's parents. Also, whole plants are not individual cells.

Final answer:

The evidence that a feline skeletal muscle cell divides and produces two genetically identical daughter cells supports the idea that mitosis is the process through which heritable information is passed from parent to daughter cells.

Explanation:

The scenario that best supports the idea that heritable information is passed from a parent cell to a daughter cell through the process of mitosis is the example where a feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells. During mitosis, a single cell divides to produce two identical daughter cells, each with an identical set of chromosomes. This cell division ensures that the genetic information in the parent cell is accurately duplicated and passed on to each daughter cell, maintaining genetic consistency in the types of cells produced. This is how heritable information is preserved during growth and tissue repair in multicellular organisms.

An INHIBITORY Signal is sent between neurons when (A)Na+ rushes into the neuron.

Explanation:

An INHIBITORY signal is sent between neurons when Cl- rushes into the neuron.

Explanation:

Inhibitory signal essentially pushes or slows the neuron’s brakes and inhibits the threshold to trigger an action potential.  

Inhibitory signal occurs at synaptic membranes of neurons when neurotransmitters like GABA are released at the inhibitory synapses triggers an inhibitory postsynaptic potential. The neurotransmitter binds with Cl- ions and rushes the cl- ions into the neurons and hyperpolarizes the synaptic membrane. This will inhibit the neuron’s threshold to trigger an action potential.
