Answer:

<em><u>FACT</u></em>

Explanation:

<h3>Cells as Building Blocks</h3>

<h3>A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms</h3>

Explain the relationship between polypeptides and proteins .
Hatshy [7]

Peptide bonds, and proteins. Amino acids are the monomer building blocks of proteins. When two are joined together in a peptide bond, they form proteins.A polypeptide is amino acids that bond to each other one at a time to form a long chain held together by peptidebonds

.Polypeptides and proteins are natural and essential organic compounds of a cell. They are both composed of amino-acids. Amino-acids are naturally occurring compounds which link together to form peptides, polypeptides, and proteins. Each amino-acid contains one amine (-NH2) and one hydroxyl (-COOH) group, as well as a specific side chain (R group). The side chain group varies in size, shape, charge, and reactivity, and is therefore unique to each amino-acid. There are 20 types of monomeric amino-acids capable of linking together in different combinations, thus conferring polypeptides and proteins with a high diversity.

A polypeptide is a polymer with a defined sequence of amino-acids linked together through covalent peptide bonds. A peptide bond is the result of a condensation reaction between two amino-acids: the carboxyl group of one amino-acid reacts with the amino group of an adjacent amino-acid, releasing a molecule of water (H2O).  

Proteins are structurally and functionally complex molecules. The term protein is used to describe the three-dimensional structure formed by the folding of one or more polypeptides. Proteins present four levels of structural organization, with the polypeptide being the primary structure. A protein has a secondary structure when polypeptide chains form α helices and β sheets.

HELP ASAP PLEASE!!!!
Tems11 [23]

Answer: The correct answer is A. During this time, cells take in nutrients, which are important for energy, growth, and repair of the cell.

Interphase is the first phase of the cell cycle. During this phase, the cell takes in nutrients, which are important for energy, growth, and repair of the cell.  

In other words, cell prepares for division by growth, synthesizing essential proteins, and duplicating the DNA. This phase occurs prior to cell division.

This phase is primarily divided into G1, S, and G2 phase. G1 and G2 are the gap phases during which cellular growth and synthesis of essential proteins take place.

S phase ( synthesis phase) includes the duplication of the DNA so two identical cells are obtained after cell division.

Thus, the correct statement, which describes the interphase is A.
