Humans are diploid organisms, and their gametes contain 23 chromosomes. Fill in the blank in each sentence using the terms. Each
USPshnik [31]

Answer:

2n, n, diploid

Explanation:

<em>When the somatic cells of human are in interphase, the ploidy level is denoted as </em><em>2n (diploid)</em><em>. The ploidy level of the human's gametes is denoted as </em><em>n (haploid)</em><em>. The 2n number of a human is </em><em>diploid</em><em>.</em>

Somatic cells are also known as vegetative cells and all somatic cells of humans have diploid number of chromosomes. At interphase, the number of chromosome remains diploid (2n) but the amount to DNA is doubled at the synthesis phase of the interphase.

Human gametes are formed through meiosis - the division of sex cells in the human body. Meiosis results in the halving of number of chromosomes of cells. Hence, all human gametes contain half the number (n = 23) of chromosome of vegetative cells.

Humans are diploid organisms with diploid (2n = 46) number of chromosomes in their vegetative cells.

Which of the following cannot be used as a metabolic control mechanism?
Luden [163]

Answer: Enzyme compartment cannot be used as metabolic control mechanism.

Explanation: Metabolic control or regulation employs many substrates,enzymes and byproduct to send a signal to cells to perfom or stop perfoming certain duties. Too much glucose for instance will regulate, activate and send signals using insulin to store glucose in form of glycogen using the process of glycogenolysis. Hormones and enzymes will also signal to activate the process of sleep, menstruation, digestion etc activating and regulating different kind of cells.

On the other hand enzyme cormpartmentation is there to maintain order and protect cells from lysis by making sure that each enzyme and cell works in its own confined space.
