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.
Answer:
The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation
Answer:
1. Sympathetic input increases ventricular contractility, thereby increasing stroke volume.
2. Sympathetic input decreases conduction time within the heart, decreasing the delay between atrial and ventricular contractions.
3. Sympathetic input increases the speed of ventricular contraction.
Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes.
