Answer:
This blank space in this question is COMPETE
Explanation:
This question is describing natural selection, which is the theory proposed by Charles Darwin where he stated that organisms that are better suited for an environment will survive and reproduce better than others.
In the environment, resources such as food, water, mate etc are limited, hence, organisms must COMPETE for the available ones. In this case, organisms that are better adapted will triumph over others. Therefore, it is certain that not all organism that are born can be supported by the environment because organisms COMPETE for resources.
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.
Answer:
Option (2) and (5).
Explanation:
RNA is present as a genetic material in some viruses only. RNA is a single stranded molecule that can be found in the nucleus as well as cytoplasm. The nitrogenous bases present in RNA are adenine, uracil, guanine and cytosine.
RNA contains ribose sugar in its structure. The translation of RNA occur in the cytoplasm by the process known as translation.
Thus, the correct answer is option (2) and (5).
