Answer: The number of codons in the sequence is 21.
Explanation: A codon is a triplet of nucleotide which codes for a specific amino acid. Each amino acid has at least one codon that codes for it. Three nucleotide residues is required to form a codon and to code an amino acid. Since there are 63 nucleotides in the sequence, the number of codons present in the sequence is 63 divided by 3. 63/3 = 21

. 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.

An INHIBITORY signal is sent between neurons when __________ rushes into the neuron.
A. Na+
B. K+
C. Cl-
D. Ca-
An INHIBITORY Signal is sent between neurons when (A)Na+ rushes into the neuron.
Explanation:
When one spot of membrane supports an action potential, lots of \text {Na}^+Na+start text, N, a, end text, start superscript, plus, end superscript ions hurry into the cell by that spot. These ions radiated out sideways into the cell and can depolarize a nearby spot of membrane, stimulating the hole of voltage-gated sodium channels and causing the nearby spot to support its action potential.The action potential can only move in one direction – from the cell body towards the axon terminal – because a spot of membrane that has just experienced one action potential is in a “refractory period” and cannot withstand another.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.
Carlos and his family were camping over the summer and came across the fossil picturered above. When school started, Carlos asked his parents if he could share the fossil with his class. Carlos told his peers he discovered the fossil within a particular layer of rock. What type of rock was this fossil most likely found in?
Answer:
Sedimentary
Explanation:
Almost all fossils are preserved in sedimentary rock because Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.

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.
Answer:Both Carl and Abby are correct.
Option B
Explanation: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.

what is the complimentary strand to AGG-CTA_AAC
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.

What are several adaptations that leaves have undergone? Why do leaves have adaptations in different parts of the world?
Explanation:
example= leaves of plants, in Africa, point downward because Africa gets little rain if any. the leaves point downward because it directs the rain to the root of plant.
so, parts of the world, like rainforest, leaves are shaped like "cups" that animals that live in trees, can drink the h2o from leaves, Instead of leaving their habitats. if they were 2 travel downwards, preditors lurk,(snakes, chimpanzees, etc...) would be preditors...
What kind of pollution might cause whales and dolphins to strand on beaches?
Marine pollution is the cause for dolphins and whales to strand on beaches.
Explanation:
Marine pollution is caused by the combination of chemicals and trash, industrial and residential waste, plastic waste, etc that are washed away from land sources into the ocean which causes harmful effects to the health of marine living organisms.Frequently dolphins and whales strands on the beaches because of the plastic wastes that are consumed by whales and in case of dolphins some plastic stuck up in their nose which blocks to them breath freely thereby resulting to death.These organisms die because of pollution and changes in the direction tides push these dead animals to shore.A parent cell gives rise to daughter cells with identical genetic information. Which of the following data supports the idea that heritable information is passed from a parent cell to a daughter cell through the process of mitosis??
A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.
A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.
A human sperm fuses with a human egg cell, resulting in the development of a new human.
A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.
Answer:
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.

Explain the value or importance of using to International System of Units when describing motion. Provide an example that supports your reasoning.
The International System of Units is used just for convenience and easy communication of these scientific units.
Explanation:
International unit system is the modern system of units used to measure quantities like length(m), speed (m/s), mass (kg), temperature ( Kelvin), etc. is makes easier for people from different countries to understand.If we take the example of motion, where it is measured in meters as per International unit system if you like to say that I moved 4 m away from the chair. People who have an idea on what is a meter can only make a sense of what he says. Hence, there is a need for an International System of Units to make sense of measurable scientific quantities to people from different countries.Gametes are haploid, while somatic cells are diploid. What is the difference between a haploid cell and a diploid cell
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.

what is the independent variable mean
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.

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.

A maglev train uses powerful magnets to lift the train above the tracks as it moves forward. Such a design reduces what following force.
A rolling friction
B gravity
C air resistance
D fluid friction
A. Rolling Friction
Explanation:
Maglev is train transportation that uses magnets. Maglev will have two sets of magnets, the function of the first set of the magnet is to repel and push the train and lift the train from the track and the function of the second set of the magnet is to elevate the train further. In this process, the lack of friction is the main advantage.Guideway is the magnetic coil running along the track and it repelling the big magnets present on the undercarriage of the train. This repulsion causes the train to go up by 1 to 10 centimetres above from the guideway. All the maglev trains are floating on the magnetic cushion and it reduces the rolling friction.Answer:
