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.
A diverse set of ecosystems means that there will be a wide variety of selection pressures exerted on the organisms. Therefore, natural selection will act to bring out the best suited traits for that particular ecosystem. The more the ecosystems are diverse, the more will be the difference between the traits between the organisms that will survive. This means that the biodiversity will increase.
Wait I’m lost is this a question?
Generally, 10% of total available energy is transferred to the next trophic level in any food chain. Rest about 90 % of the stored chemical energy is lost as heat, a by-product of respiration. Let’s assume a 10% transfer rate, starting from producer (100%), primary consumer (10% ), secondary consumer 1%) and tertiary consumer have (0.1%). Therefore, quaternary consumers will have less than 0.1% of energy. Thus, statement is true.
