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
A small town is located near a body of water and enjoys cooler temperatures than other areas in the same climate zone. This is an example of a microclimate
Explanation:
- The microclimate is nothing but experiencing a different temperature, which is restricted to a certain area only. It might be experiencing a lower temperature in comparison with the surrounding regions.
- The dry climate is experiencing a very high temperature and polar climate is nothing but a region where there are no warm summers and the temperature would be less than 10 degree Celsius.
- Climate zones are characterized by distinct parameters and these are found near the poles
Answer:
The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass. There are four types of fronts that will be described below: cold front, warm front, stationary front, and occluded front.
Answer:
The statement is false.
Explanation:
Passive transport moves molecules from one side of the membrane to the other with the energy of the chemical gradient (or concentration gradient). Otherwise, active transport uses the hydrolyzation of ATP to gain energy in order to move molecules across the membrane without taking into account the gradient.
<h2>Scientist Observing changes </h2>
If the population of the species is significantly decreasing then the species could become extinct. The decline in population is due to some factors like less immigration, aging, and decreasing fertility rates. But the most is due to less immigration which causes to decrease population. The extinction of population can be prevented by some serious actions which should be taken government.
