Answer:

c. A chromosomal mutation can change the total number of chromosomes in the cell.

Explanation:

A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.

The bottom line difference between passive and active transport through a cell membrane’s is

Ahat [919]

<h3><u>Answer;</u></h3>

Active transport uses energy and passive transport does not

<h3><u>Explanation</u>;</h3>

<u>Passive transport occurs when materials move across cell membranes without using cell energy (ATP). </u> Examples of passive transport include; diffusion, facilitated diffusion, and osmosis. It moves small molecules like water, oxygen, carbon dioxide and glucose.
<em><u>Active transport on the other hand involves the movement of materials across the cell membrane that requires the use of cell energy (ATP)</u></em>.
In other words the difference between active transport and passive transport is that passive Transport moves ions from high concentration to low, using no metabolic energy while active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

nirvana33 [79]

Answer:

The right answer to this question is option D. Convergent evolution.

Explanation:

Convergent evolution is a process defined by when an organism develops the same, or at least near that, characteristics, for a specific reason, but they don't have the same origin. In this case, the cacti in both deserts have pretty much the same characteristics, and this happens because both these plants need water to survive, and in order to save it, they have barrel-shaped stems, short-lived leaves, and spines. All of these things help them in saving the water and capturing it when it's possible.

The convergent evolution is when both these organisms develop equally, but are not originally from the same place, the environment being the one to shape this.
