Answer:
signal molecule is a general term for molecules also called (ligands)that bind specifically to other molecules (such as receptors). hope it helps!!
Answer:
Las células procariotas están rodeadas por una membrana plasmática y al igual que las células eucariotas tienen ADN, citoplasma y ribosomas. También tienen paredes celulares y pueden poseer una cápsula celular. Los procariontes tienen un solo cromosoma de gran tamaño, que no está rodeado por una membrana nuclear.30-Jan-2013
Answer:
The reactants and the products of photosynthesis and cellular respiration are the same but switched around.
Explanation:
For photosynthesis light energy, carbon dioxide, water are needed to create glucose and the<em> waste product</em> is oxygen. But for cellular respiration the things needed to create energy to move around are oxygen and glucose. Mitochondria (aka the powerhouse of the cell) breaks down the glucose to make ATP energy (Adenosine Triphosphate). Plants store some leftover oxygen for cellular respiration. So basically, photosynthesis and cellular respiration kinda depend on each other.

The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
