Answer:
A
Explanation:
A. The optimum pH of the enzyme is 6.6. - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)
B. The optimum pH of the enzyme is 5.8. - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80
C. The enzyme's activity is greater around pH 8.0 than around pH 5.0 - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.
D
. The enzyme's activity continually increases as pH increases from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.
A wavy-haired parent can either contribute a C or an s, so two wavy-haired parents have a fifty percent chance of having a wavy-haired child, a twenty-five percent chance of having a curly-haired child, and a twenty-five percent chance of having a straight-haired child.
Answer: The five kingdoms are: <u>animal, plant, fungi, protist and monera. </u>The system of biological kingdoms is the way in which science classifies living things according to their ancestry over the course of evolution. they also have common ancestors and therefore share some of their genes and belong to the same family tree.
Hope this helps!
Answer:
The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. ... During interphase, the cell grows and the nuclear DNA is duplicated.

Answer:
5%
Explanation:
The adrenal cortex in both males and females produce a small amount of weak androgens. One of the major weak androgen secreted by adrenal cortex is dehydroepiandrosterone (DHEA).
Levels of dehydroepiandrosterone secretion exhibit changes with age. The dehydroepiandrosterone secretion increases till the age of 20-24 years and falls off with increasing age after the age of 30 years in both males and females. The DHEA production at the age of 80 years is about 5% of its secretion at the age of 30 years.
