After a copper smelter begins operation, local downwind populations of plants begin to adapt to the resulting air pollution. Sci

entists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of:
A) stabilizing selection.
B) disruptive selection.
C) genetic drift.
D) directional selection.

Answer: Directional selection

Explanation:

In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.

This causes the allele frequency to shift towards the time in the direction of that particular phenotype.

Here, in the question the acid tolerant plant species is favored over the other phenotype.

Hence, the correct answer is option D

Which body systems help the respiratory system move gases between the lungs and the cells of the body?
mars1129 [50]

Answer:

The Cardiovascular System

Explanation:

The respiratory system draws air into the lungs.  Oxygen diffuses through the walls of the alveoli and across the walls of the capillaries where it enteres the bloodstream.  The oxygen molecules are picked up by red blood cells, which are pumped through the blood vessels by the action of the heart.  As the red blood cells carrying oxygen pass through capillaries near the cells, oxygen diffuses into the cells.

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death ________ whereas
Aliun [14]

Answer:

time; point

Explanation:

The complete question is as follows:

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death __________ whereas the lowest temperature required to kill all microbes in a sample within 10 minutes is the thermal death _________.

time; point

window; point

point; time

time; temperature

  • When a population of bacteria gets killed due to exposure to high temperatures then this is termed as thermal death.
  • The time taken to kill a specific microbe at a specific temperature is termed as the thermal death time. The length of the time taken depends on the nature of the target microbe and hence, varies from one to another.
  • The lowest temperature that will kill all the microbes in a sample within ten minutes is defined as the thermal death point. The temperature at which the microbes get killed within 10 minutes also varies from one microbe to another.
  • Thermal death results in the disruption of the cell membranes of the microbes and hence can kill the microbes.
