Global cooling across the Eocene-Oligocene transition is hypothesized to be driven by

(a)removal of CO2 from the atmosphere through enhanced weathering

(B)Tectonic reorganizations, establishment of a new circumpolar ocean current, and
glaciation of Antarctica

(C)decrease in global volcanism associated with lower atmospheric CO2 levels

(D)O destabilization of methane hydrates

answer: c.

explanation:

the correct answer is:

a population changes in response to a change in the environment.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
