Answer:
- Numerous amino acids <u>allow for proteins to perform many diverse functions in organisms</u>.
- The branching structure of some carbohydrates <u>maximize the amount of glucose available for quick energy</u>.
Explanation:
Amino acids are the <u>building blocks</u> of proteins. In humans, <u>all forms of proteins</u> are made up of <u>20 different types of amino acids</u>. The <u>sequence of amino acids</u> is the key to the production of <u>specific proteins</u>. If the sequence is changed, the target protein will be changed. So, only 20 types of amino acids can produce millions of proteins through different combinations. For example, for a protein with 4 amino acids sequence, 160,000 types of polypeptide chains can be formed (20 X 20 X 20 X 20). Since we know that proteins are key players in cell functioning, their multiple combinations lead to diverse functions in the organisms.
Carbohydrates are an <u>excellent source of energy</u>. Although branching decreases the water solubility of carbohydrates, it <u>compacts the energy-yielding monomers</u> in a <u>small space</u> so that they can be <u>stored</u> and, during starvation, they can produce an <u>extensive amount of energy</u> for long term survival. Carbohydrates in <u>animal and plant</u> bodies are stored as branched structures of <u>glycogen and starch</u>, respectively.
The answer is C; it isn't performed by cancer cells. This statement is untrue. Cancer cells are indeed capable of reproduction by cell division... in fact, according to most evidence today they appear to be better at it than normal cells.
Hope this helps!

Answer:
I think you mean 'Prophase' and I'm going to give you the definition
Explanation:
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
Answer:
It connects the brain to the rest of the body.
