Answer:
Transport proteins allows only enzymes to pass through the membrane
Explanation:
During transcription, mRNA is synthesized using DNA as a template. This process usually takes place in the cell nucleus and is carried out with the help of an enzyme called RNA polymerase.
mRNA plays the role of a messenger hence the term messenger RNA or mRNA in short. Information for synthesis of a specific protein is transcribed on mRNA in the nucleus of the cell. The mRNA then leaves the nucleus and enters the cytoplasm and attaches onto a ribosome. Ribosomes are cell structures fondly called the "work bench " of the cell.
It is in the ribosomes that the information brought by mRNA is translated or decoded and used to synthesize the specific protein that was coded for.
Answer:
Thymine
Explanation:
Adenine is a Purines together with Guanine .
Purines always pair with Pyrimidines ; which are cyosine and Thymine.
This is a complementary base pairing that hold the two strands of DNA bases together by weak hydrogen bonds for flexibility and easily unwind during replication
Purines are larger in size beaxuae they have 2 ring structures while Pyrimidines aee smaller because of one ring structure.
Therefore two purines (Adenine and Guanine can not pair together;
It must be a Purines -Pyrimidines pairs.
Therefore Adenine must pair with Thymine and cyosine with Guanine
In RNA, Thymine are replaced with URACIL as Pyrimidines.

Answer;
-Correlational; experimental
Two main types of designs used specifically in human lifespan studies are correlational and experimental.
Explanation;
-Psychological studies vary in design. In correlational studies a researcher looks for associations among naturally occurring variables, whereas in experimental studies the researcher introduces a change and then monitors its effects.
-An experiment isolates and manipulates the independent variable to observe its effect on the dependent variable, and controls the environment in order that extraneous variables may be eliminated. Experiments establish cause and effect. A correlation identifies variables and looks for a relationship between them.
