Answer:
buffers
Explanation:
Buffers neutralize acids and bases.
Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then
So it has to be D
Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.

A massive landslide Mud flows in the Toutle river.
<h3>How changes have occurred in the North Fork Toutle River?</h3>
There had been many earthquakes in the area prior to eruption but this happen to be a massive land slide because a moving magma have over steepened the mountain slopes.
This geologic process uses gravity to cause rock, soil, artificial fill or a combination of the three to move down a slope. Slow weathering of rocks as well as soil eruption and volcanic activity also causes landslides
Thus, massive landslide Mud flows in the Toutle river.
