Consider a major environmental change (like antibiotics entering a person's body). If there are not organisms in a population th

at have traits that allow them to still continue to survive to reproduce, what would likely happen to that population?

Answer:

The population (of the bacteria) will reduce

Explanation:

This question appear a little confusing because of the structure of the second sentence. However, it appears to describe how an antibiotic works. Antibiotics work against bacteria by either making the environment toxic for the bacteria (which kills it) or inhibiting the growth/reproduction of the bacteria. Both patterns will eventually lead a sharp reduction in the population of the bacteria. Even if what the antibiotic does is to inhibit the reproduction of the bacteria, this act provides the body with an opportunity to fight the "unreproductive" remnants of bacteria thereby leading to the reduction of population of the bacteria.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.

Refer to the paragraph about the formation of the isthmus of panama. the sister populations on opposite sides of the isthmus are
Dimas [21]
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.

Describe the role that wind plays on surface currents.
vovikov84 [41]

Answer:

Wind, an indirect form of solar energy, moves the surface currents while the surface currents itself also rotate in circular patterns due to the earth's rotational force.  They are both part of the Coriolis effect.
