Genetic drift occurs when there is no random mating across a population. This causes a change in allelic frequency due to a random sampling of the population.
As the aboriginal population explored the earth, a small part of the population became geographically isolated either due to continental drift and climate changes. As the isolated population grew bigger, they established their own gene pool. This resulted a change in genotypic frequencies from that of the aboriginal population.
The correct answer is option C
The demand for a better life increased the pollution in the society. The increased pollution in the environment led to many health problems.
The Nuclear power plant creates radioactivity and thermal pollution.
The water used in the nuclear power plants is very warm and causes thermal pollution as it is released into water bodies.
The nuclear power plant uses radioactive substances like uranium and the waste that is left is radioactive waste.
Answer:
B. Multipotent cells
Explanation:
Multipotent stem cells are the one that develops from pluripotent stem cells during embryonic development. The multipotent stem cells are the stem cells which have specific functions. These cells develop into specific cell types to replace the older cells.
For example, keratinocytes are the multipotent cells of the skin that produce new skin cells. Spermatogonia are the multipotent cells present in testes so that they can form sperms.
The storage areas are called : Reservoirs Reservoirs can both be made by nature or crafted by men. In order to make our lives became easier , we could create our own reservioir by digging up an open land to form a space that could contain water when its raining, as a back up resources when the lake or rivers are drying up
Foxes Hawks and Owls will have to rely on other sources for food and be the most directly effected. You could make the argument that all the organisms will effected as some will see increased predation, while the plants will see a reduction in herbivores eating them.
