The animal fauna hypotheticus has a diploid chromosome number of 28. it has a nuclear genome consisting of 2 x 109 bp of b-dna with a g+c content of 60%. a. determine the number of chromosomes and dna molecules in a cell: (i) during g1 of interphase; (ii) at the start of prophase of mitosis; (iii) at the end of anaphase of mitosis; (iv) after cytokinesis of mitosis; (v) at the start of prophase i of meiosis; (vi) at the start of prophase ii of meiosis; and (vii) after cytokinesis of meiosis ii.

Some differences between the sympathetic and parasympathetic nervous systems:

Explanation:

- Neurotransmitters: norepinephrine in sympathetic (adrenergic fibers) and acetylcholine in parasympathetic (cholinergic fibers)

-The sympathetic nerves have their origin in the spinal cord (between segments T-1 and L-2) and from there to the paravertebral sympathetic chain, then in tissues and peripheral organs.

- The parasympathetic nerves have their origin in the brain stem, mainly in the cranial nerve nuclei III (oculomotor), VII (facial), IX (glossopharyngeal) and X (vagus) and in the sacral medulla.
