1. A seed leaf - cotyledon
2. A flowering plant with seeds that have two seed leaves - dicotyledon
3. A food storage tissue - endosperm
4. A flowering plant with seeds that have one seed leaf cotyledon - monocotyledon
Answer:
Option C
Explanation:
Long term hunting has led to following
a) Reduction in population size and hence the gene pool
b) Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
Answer:
The correct answer is "C. Cave fish have evolved degenerated eyes because they have no use for vision in dark, underwater caves."
Explanation:
All of these statements about organism adaptation to its environment are true, but the real reason why cave-fish are blind is not because there's no use for their eyes in the dark, but because being blind saves them energy, as using one's vision requires the activity of photoreceptive cells and neurons, and underground caves are lacking in both food and oxygen.
Answer: B
Explanation: Most mammals have only one pair of sex chromosomes in each cell. Males have only one Y chromosome and one X chromosome, while females have two X chromosomes. In Mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development in a male.
