I think the answer is C because at the first the DNA shows the copies of itself when it replicate n then it transcripts n transfer the coded message for protein synthesis from DNA onto mRNA n then it translates From the cytoplasm wher the RNA enters when it translate the part of protein synthesis from the time of amino acids are assembled in a particular sequence...The transcription happens from a nucleus
Answer: first 2 statements ie. It is essential that our diet provides these amino acids.
There are 20 essential amino acids.
In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
Iguanas have spines along their backs to help protect them from predators. They also have a bunch of extra skin below their necks called a dewlap. This dewlap helps them to regulate their temperature, which is helpful as they are cold-blooded and their bodies don't control their body temperature automatically.
