Answer:
The correct answer is "p18, p21 and p27".
Explanation:
In this experiment, four proteins were blocked and the level of DNA replication was tested in different cell cultures to see which proteins may play a role in cell cycle. Based on the given data we can conclude that p16 is the only protein that appear to have a pivotal role in cell cycle, while p18, p21 and p27 apparently does not. We can conclude this by observing group 7 of cells, were cells have only p16 active and were able to have around 80% of DNA replication.
Answer:
Many of the details of the Temperature-dependent sex determination (TSD) behind molecular mechanism is still mysterious and the molecular link between environmental temperature and sex determination patterns is yet to be discovered.
Explanation:
Temperature-dependent sex determination (TSD), in reptiles, is a sex determination mode in which the incubation temperature during a critical temperature sensitive period (TSP) determines sexual lead of the individual rather than the individual’s genotypic background.

Answer:
Tumor in the hypothalamus. (Ans. B)
Explanation:
Hypothalamus is known as the small part of the brain which is situated at the base of the brain. It's very small in structure but plays an important role in the human body such as:
1) Releasing hormones.
2) Body temperature regulation.
3) Managing sexual behavior.
4) Managing daily physiological cycles.
Hunger triggering hormone also released by the hypothalamus which is known as orexin. Tumor in the hypothalamus can trigger the secretion of orexin hormone which makes the person eats excessively and never seems to feel full.
Answer:
Food webs are the best depictions of feeding relationships because they show a single path for the flow of energy through an ecosystem.
Food webs are the best depictions of feeding relationships because they show a single path for the flow of energy through an ecosystem.
Explanation:
• Note that a food web is only a single path with to and fro direction.
