When doing medical research with human subjects, the following are unavoidable limitations;
It’s often impossible to repeat trials on the same subjects.
Subjects may report an inaccurate medical history.
It can be difficult to control all possible variables
There are ethical or privacy concerns to consider.
Explanation
When doing a medical research that involves human subjects it should be voluntary, informed and consent. The researchers should respect the persons treated as autonomous agents. The volunteers should be protected from physical, mental and emotional harm. The benefits should outweigh the costs.
<span>In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons (energy).</span>
Answer:
A population bottleneck occurred, altering the resulting allele frequencies.
Explanation:
A population bottleneck occurs when the size of a population is reduced by at least a generation. In this case, genetic drift acts more quickly to reduce genetic variation in small populations, but going through a “bottleneck” can greatly reduce variation, even if the bottleneck does not last for many generations. This effect called a bottleneck usually happens when a major disaster occurs in the population's habitat, changing the allelic frequencies and even the genetic variability of the population.
The population bottleneck can be seen in the question above, where after a forest fire, only 20 beetles remain in a population of beetles. 18 of them are green and 2 of them are brown.
Answer:
<em>ATP synhtesis in both chloropasts and mitochondria involves the process called CHEMIOSMOSIS.</em>
<em>Explanation:</em>
<em>Chemiosmosis is when ions move by diffusion across a semi permeable membrane , such as the one inside mitochondria. The function of this process is the production of adenosine triphosphate (ATP), that is the main molecule utilized for energy by the cell. Eukaryotics cell produces ATP during cellular respiration in the mitochondria .</em>
