<u>Answer:</u>
Cellular respiration:

Photosynthesis:

<u>Explanation:</u>
The process of breaking down the sugar into a form of usable energy by the cell is called cellular respiration.
It can be shown by an equation as:

So the product here includes ATP which is the energy along with carbon dioxide and water.
While photosynthesis is the process where sunlight is used to convert the carbon dioxide into sugars to be used as energy.

Here the products are sugars, oxygen and water.
Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
Answer:
Explanation:
Snakes, like all reptiles, are cold-blooded (also known as ectothermic). This means they regulate their body temperature by lying in the sun to warm up, or moving into the shade to cool down. Snakes that live in cold climates like ours must seek refuge in a hibernaculum throughout the winter
