Answer:

<u><em>The above statement is true.</em></u>

Explanation:

A proto-oncogene can be described as a gene which is normal but if mutation occurs then it can be converted into a cancerous gene. Proto oncogenes have different functions to perform. Some of them act as signals for cell division while others might be involved in the process of apoptosis. A point mutation can be described as a mutation by which just a single nucleotide gets changed. Even a change in the single nucleotide can cause a proto oncogene to convert into an oncogene and cause cancer.

A plant produces its own food through the process of photosynthesis. Which of the following materials do plants need in order to
slavikrds [6]

The materials plants need in order to perform photosynthesis are Water and carbon dioxide.

<h3>What is photosynthesis?</h3>

Photosynthesis is a process of converting light energy into chemical energy.

Photosynthesis is performed by chlorophyll-containing plants to produce their food.

The process of photosynthesis is carried out in the presence of sunlight.

It requires water, carbon dioxide, and sunlight.

Thus, the correct option is B, water, and carbon dioxide.

A parent cell gives rise to daughter cells with identical genetic information. Which of the following data supports the idea tha
Yuri [45]

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 <u>feline skeletal muscle cell</u> undergoes cell division, resulting in two <u>feline skeletal muscle cells</u>.

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

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

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 <u>long-stemmed</u> plant reproduces with a <u>short-stemmed</u> plant, and the offspring are all <u>long-stemmed</u>.

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

A) Explain why antibiotics would kill a prokaryotic cell. (2 points)
lisov135 [29]

Answer:

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.

Explanation:

Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.
