Answer:
A tetrad is a four part structure formed during the prophase I of meiosis I which is formed by the homologous chromosomes which is composed of two identical chromatids.
The tetrad formation takes place when a proteinaceous meiosis-specific nuclear structures called synaptonemal complex is formed between two homologous chromosomes which mediates the tight associations of the homologous chromosomes.
The synaptonemal complex consists of two ladder like lateral elements which attaches the chromatin of the homologius chromosomes. The central region of the synaptonemal complex is composed of the transverse filaments and the central element which bridge the space between the the lateral elements.
This attachment of the chromatin to the synaptonemal complex mediates the chromosome pairing and form tetrad.

Groundwater is the largest available source of freshwater - up to 90%. It supplies drinking water especially to rural areas. They are also used to irrigate crops.
Answer:
innervation of the sympathetic nervous system
Explanation:
Based on the information provided within the question it can be said that this lower urine output is primarily due to innervation of the sympathetic nervous system. This supply of nerves then increases the pressure which tightens the afferent arteriole, and is what prevents urine from passing through. Hence why the urine output is only 4 mL over the first hour on arrival.
