Answer:
A: Unlike DNA, XNA replicates conservatively
Explanation:
<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>
In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.
Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
More rainfall leads to the growth of the grass in a tallgrass prairie to grow so tall.
Answer: Option B.
<u>Explanation:</u>
The tallgrass prairie consists of big and little blue stem, switchgrass, and Indian grass. These were the species which thrive in the area which receive rainfall in large amount. The rainfall in these areas are in the amount of 30-40 inch annual precipitation.
Because these areas receive rainfall in such high amount, the grasses grow very tall. The height of these grasses reach to approximately 6-8 feet in height.
I think it is the secondary ovarian follicle that contains the secondary oocyte.The stages of the ovarian cycle that the follicle will go through includes; a primary follicle contains an oocyte and begins producing estrogen. Then the secondary oocyte contains a secondary oocyte and produces estrogen and some progesterone, then the graafian follicle develops and the secondary oocyte is released a process we call ovulation. the corpus luteum produces progesterone and some estrogen and lastly the corpus luteum degenerates.
The sporophyte represents Asexual form of the plant, the gametophyte represents the sexual form of the plant
