Answer: blood calcium level
Explanation:
There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity
, systemic blood pressure, and renal artery/arteriole diameters.
Filtration membrane integrity
: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.
Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.
Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.
Blood calcium level do not have any role in the kidney filterate formation or renal regulation.
Hence, the correct option is blood calcium level.

Answer:
The order in the cladogram is the following:
4 > 5 > 3 (taxon 3 share a node with taxon 5)
>6 >1 (taxon 1 share a node with taxon 6)
>2
Explanation:
In this example, taxon 4 is the most basal in the group and taxon 2 is the terminal taxon (i.e., the most recent). Each taxon is a branch of the cladogram tree.
A cladogram is a cladistic tree that exhibits relationships among groups of organisms. A cladogram may have an evolutionary meaning, and therefore evolutionary relationships may be inferred by using this tree. The values 1 and 0 are states of the character and they are used to infer associations in the cladogram. Each branch in the cladogram is referred to as clade, which includes a common ancestor with all its descendants.
This is an example of enzymatic allosteric regulation. Allosteric regulation is characterised by the binding of an inhibitor to the enzyme by another location in it different from the binding active site. Allosteric has its origin from the Greek meaning: another space.
This can also be considered an example of negative feedback. As glucose 6-phosphate increases in quantity, more hexokinases are inhibited stopping the reaction that produces more glucose 6-phosphate.
