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.
Answer:
The correct option is D.
Explanation:
In the year 1952, two scientists, Hershey and Chase conducted a series of experiments that helped to establish the fact that DNA is a genetic material. The DNA is located inside the nucleus of living cells in form of chromosomes and its the determinant of traits that are found in living organisms. During protein synthesis, the information in the DNA molecule is encoded into an RNA molecule and this is used in the production of protein, thus, DNA actually directs all the happen in the living cells.

Answer:
No.
Explanation:
No, Surtsey island and Iceland newest volcanic island will not become an atoll because these islands have no underground volcanoes. The atolls are only occur when the volcanoes are present underwater and we know that these volcanoes are present on the lands not in the water so there is no possibility of having atolls in these Surtsey and Iceland volcanic islands
Answer:
The Chromosomal Theory of inheritance, proposed by Sutton and Boveri, states that chromosomes are the vehicles of genetic heredity. Neither Mendelian genetics nor gene linkage is perfectly accurate; instead, chromosome behavior involves segregation, independent assortment, and occasionally, linkage.
