Really, this is a simple and easy question.
To make it easier to understand, consider a population of moths. These moths are originally white. The trees in the area are a color that allow the moths to camouflage to escape predation.
There is a particular woodland that these moths most reside in, but as industrialization increases in the area, the emission of smog increases, which darkens the trees, this changing the moth's habitat. Due to this environmental change, some moths become darker in color due to the smog emissions on the tree bark. Some mlths, however, are still bright in color. Due to this environmental change, the bright-colored moths are not able to survive and reproduce, and their population eventually dies out.
This is one of the rather basic examples of natural selection.
To answer your question, therefore, the population would eventually die out, due to those organisms not having the compatible adaption for their environment, which line up with the natural selection principle.
Hope you find this helpful.
I think you just answered your question. They encourage adolescents to eat calcium-rich foods because it aids in bone formation, like you said.
Answer:
The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval
Explanation:
Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.
Gametes are the cells used during sexual reproduction to produce a new individual organism or zygote. The male gamete, sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova. Both sperm and egg are only haploid cells. They only carry half of the chromosomes needed.
It is called a Double Helix.
