Answer:

a.Over time, a caterpillar species becomes as green as the leaves it eats.

Explanation:

<em>Evolution means the gradual formation of complex organisms from simple types, a process that usually take several years (geological time).</em>

The gradual change happens as a result of continuous adaptation by organisms to ever changing environment.

Option b could have been considered along with option a, but evolution process takes much more than 50 years.

Hence, the correct option is a.

During light reactions, ATP is produced when hydrogen ions move:
Natalija [7]

Answer:

The correct answer will be option-C.

Explanation:

Light-dependent reactions are the reaction of photosynthesis which takes place in the presence of light.

During light reaction, ATP and NADPH intermediates are produced which are utilized during the light-independent reaction. The main reactions that take place during light reactions are photolysis of water and ATP synthesis due to the electron transport chain.

Electron transport chain generates electrochemical gradient across the thylakoid membrane sue to the accumulation of protons in the thylakoid lumen and fewer protons in the stroma of the chloroplast.

This causes the osmotic movement of protons down their concentration gradient through ATP synthase. The movement if hydrogen ions take place from thylakoid lumen to stroma forming ATP molecules.

Thus, Option-C is the correct answer.

Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. As the Earth travels around the Sun, the hemisphere that is tilted towards or away from the Sun changes.

What type of chromosomal abnormality can lead to multiple copies of a gene, some of which can incur mutations that can lead to t
koban [17]

A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.
