Answer:
Two amino acids are joined together by losing a water molecule, or hydrolysis.
Explanation:
A peptide bond is formed by binding two or more amino acids. This is a kind of covalent bond, wherein the <u>carboxylic group</u> of one amino acid and an <u>amino group</u> of another amino acid is linked together with a <u>loss of water molecule or hydrolysis during the process</u>. A polypeptide chain is now then composed of multiple peptide bonds, from binding amino acids (also known as <u>residues</u> at this point), with a linear configuration.
A closer look into this process involves the <u>α-amino group as the beginning</u> of the polypeptide series and <u>ending with the α-carboxyl group</u>. This also serves as the primary structure of the protein.
Answer:
False. Bone can be classified as a connective tissue because it provides support and structure to the body.
Explanation:
Connective tissue is those tissues that fill spaces between organs and other tissues, and also provide support to the organism. It is characterized by the presence of different types of cells separated by intercellular material synthesized by them.
The bony tissue is the principal structural and supportive connective tissue that differs from the other connective tissues because its extracellular matrix is mineralized, which makes it possible to accomplish its support and protection function due to its rigidity and hardness. The mineral that deposits in the osteoid matrix is the calcium phosphate, composing hydroxyapatite crystals. The bony tissue is a storage site of calcium and phosphate, which are available for maintaining constant the calcium blood levels according to the individual physiological needs.
The food that is undigested and fails to break down becomes stool because it can not be used.
Over the years, greater controversy has arisen over environmental issues as the issues addressed have become more complex and less easily identifiable.
