Answer:
Norepinephrine
Explanation:
Nerve cells and circulating hormones are the one responsible for vasoconstriction of the vessel walls, as they do not enter the tunica media of the blood vessel, the nerves do not synapse directly on the smooth muscle cells. Instead, they release the neurotransmitter, norepinephrine, which diffuses into the media and acts on the nearby smooth muscle cells, which result in contraction of the entire muscle cell layer and thus reducing the radius of the vessel lumen.
The given blanks can be filled with NADPH and ATP.
The dark reactions or light-independent reactions of photosynthesis refers to the chemical reactions, which transforms carbon dioxide and other constituents into glucose. These reactions take place in the stroma, that is, the fluid occupied region of a chloroplast external to the thylakoid membranes. These reactions use the products of light-dependent reactions, that is, NADPH and ATP to do further processes.
Answer:
By looking at the different possibilities.
Explanation:
By looking at which letters correspond to which, you can tell what the chances are of being what.
Have a nice day! :)
Answer:
<h2>mRNA, tRNA, and rRNA are all produced by transcription.</h2>
Explanation:
Trascription is the process through which RNA molecules are produced from the DNA template with the help of RNA polymerase/ RNA pol holoenzyme and various other factors. One strand of DNA works as a template, and according the the sequence in DNA, RNA synthesis occur in complementry way.
All type of RNA (mRNA, tRNA, and rRNA ) molecules are produced by transcription.
Insects have two pairs of wings, while bats and birds each have one pair. Insect wings lack bones, but birds and bat wings have them. Butterfly wings are covered in scales, bird wings in feathers , and bat wings with bare skin.
I hope you the answer will help you :)
