Answer:
polypeptides
Explanation:
Amino acids generally represent the building blocks of proteins. In order words, proteins are polymers of amino acids.
The amino acids in proteins are linked together by peptide bonds. <u>A peptide bond is formed between two amino acids when the amine group of one of the amino acids combines with the carboxylic group of the other with the elimination of water</u>. When the reaction involves multiple amino acids, multiple peptide or polypeptide, also known as protein is formed.
Answer:
d. Water is transported in the phloem.
Explanation:
Xylem is the vascular tissue responsible for the movement of water and dissolved minerals from roots to various plant parts. Phloem is another vascular tissue that serves mainly in the translocation of sugars. The cohesion-tension model of water transport explains that the upward movement of water from roots to the aerial plant parts is drive by transpiration pull. Transpiration of water from leaves results in a large negative pressure in xylem elements. Cohesion and adhesion properties of water maintain the water column in xylem elements.
