Answer:

The correct option is <em>C. A gene is a specific segment of DNA on a chromosome</em>

Explanation:

Option A is false because a gene is a segment on a chromosome.

Option B is false because a chromosome carries many genes.

Option D is false because a gene carries a segment of DNA, not all of the DNA.

Option C is correct because there are many genes present on a single chromosome. Each gene carries a segment of DNA. The position of a gene on the chromosome is known as its loci.

jek_recluse [69]

From the video we can infer that a group of friends went on an excursion to a zoo and saw the treatment of different animals present.

<h3>What is a Zoo?</h3>

This is a place where animals are kept for public display or for conservation purposes.

The debate between them was about the revolutionary concept of how animal treatment affects their choice selection in the zoo.

The element as to how zoos are changing that also serve the purpose of offering animals more choice include their habitat and diet.

Select the correct answer.
disa [49]

Protein recommendations are the daily dietary protein requirements for an individual based on that individual's weight.

<h3>What was the dietary protein requirement?</h3>

For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight. For instance, 60 grams of protein should be consumed daily by a person who weighs 165 pounds, or 75 kilograms.

Christine has already ingested half of the 40 grams of dietary protein that her doctor recommended. This indicated that she had already ingested roughly 20 grams of the recommended dietary protein and needed an extra source of protein to meet her daily needs. Christie must therefore have four more servings of snacks to complete her daily protein requirements.

The binding of the neurotransmitter to receptors on the motor end plate causes which of the following to occur?
lutik1710 [3]

The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.

Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter ACh binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.

How did the frameshift change the amino acids?<br> Please it’s due today
notka56 [123]
A single insertion or deletion of a nucleotide will basically lead to a frameshift mutation where the “reading frame” is disrupted. Normally, amino acids are encoded by three nucleotides, called a codon.
