Answer:
D. Each enzyme can catalyze a wide variety of different reactions
Explanation:
Each enzyme can only catalyze a few, specific types of reactions.
Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.
If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.
So, each enzyme can only assist in a few reactions.
The correct answer is D. Each enzyme can catalyze a wide variety of different reactions
It follows that no other cell in the body performs a neuron's exact functions.
<h3>
What about neurons?</h3>
- Information is transmitted via neurons.
- They communicate between various brain regions and between the brain and the rest of the nervous system through electrical impulses and chemical signals.
- The basic building blocks of the brain and nervous system are neurons (also known as neurones or nerve cells).
- The cells known as neurons are responsible for receiving sensory data from the outside world, sending commands to our muscles, and converting and relaying electrical signals at various points along the road.
- The bulk of neurons in vertebrates are found in the central nervous system, however some are found in peripheral ganglia and many sensory neurons are found in sensory organs like the retina and ear.
- A neuron is made up of a cell body, which includes a nucleus and cytoplasm, from which long, thin portions that resemble hair grow.
- The neuron's lone long component, known as the axon, is responsible for carrying nerve impulses to various body areas.
- Dendrites are the short, branching components of the neuron.

<span>1. Heterozygous black rabbit will have genotype Bb</span>
2. If a heterozygous black rabbit and a brown rabbit were crossed:
<span>Bb x bb</span>
The offspring will be:
Bb Bb bb bb
Which means that half of them will be black and half brown (50%).
Answer:
G1 phase: 2C
S phase: 4C
G2 phase: 4C
Meiosis-I: 2C and Meiosis-II: C
Mitosis: 2C
Explanation:
Let's suppose that a cell with 2C DNA content enters the cell cycle. As the G1 cell with 2C content would enter the S phase, DNA replication would double the amount of DNA. Therefore, the cell by the end of the S phase and in the G2 phase would have 4C DNA.
If the G2 cell with 4C DNA enters meiosis-I, separation of homologous chromosomes to the opposite poles in anaphase-I would reduce the DNA content to 2C. Therefore, the cell by the end of anaphase-I would have 2C content. Meiosis-II would further reduce the DNA content in anaphase-II by separation of sister chromatids to opposite poles. Therefore, each of the four daughter cells formed by the end of meiosis would have C DNA content.
If the G2 cell with 4C DNA enters mitosis, separation of sister chromatids to opposite poles in anaphase would reduce the DNA content. Therefore, each of the two daughter cells formed by the end of mitosis would have 2C DNA content.
