Answer:
Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.
Explanation:
Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
Answer:
A cell uses active transport to move molecules across a cellular membrane when the molecules are being moved against a concentration gradient.

Yes, actually.
Cause I can recall this one story that was this lady who got a McCafe and it got spilt, she got a 3rd degree burn, and yeaaahh..
Coffee can burn you pretty badly, and I just think that the employees don't want to get sued or anything, my dude
<h3><u>
Law and theory:</u></h3>
A law foretells what occurs whereas a theory proposes why. A theory may never turn into a law; however, the advancement of one regularly triggers advancements on the other.
A decent scientific law is a finely-tuned machine, achieving its assignment splendidly however ignorant of why it fills in just as it does. A decent scientific theory is a wounded, however unbowed, contender who fears defeat if unfit to adapt or over power to the next competitor.
Although unique, science needs both theories and laws to comprehend the entire picture. So, whenever somebody remarks that it's only a theory, challenge them to go nine rounds with the champ and check whether they can do any better.
