Answer:
c) Both of the parents' genotype must have been Pp.
Explanation:
A plant breeder is trying to develop more purple colored violets. She knows the purple violets she has can be PP or Pp for the purple color. She crosses two purple violets. Of the four plants that result, one is white and three are purple. Obviously, the parents' genotype must have been Pp.
Answer:
D
Explanation:
I believe D is the answer. If you can see in line D there are 3 (square and circles) that are open. And it states in the prompted that anything that is open has the trait. That is making it a probability of 75%
Oxygen
During aeroobic respiration oxigen reacts with sugar or glucose, producing carbon dioxide, water, and energy.
During anaerobic respiration when there is not enough oxygen, cells break down glucose into lactic acid and energy.
Answer: 17190
Explanation:
100-50-25-12.5 (3); 3*5730= 17190
Answer:
a. It is a hormone that acts upstream in the signaling pathway (i.e., acting as a ligand by binding to cell receptors)
b. Dopamine-mediated pathways
Explanation:
It is well known that many cellular transduction pathways are activated via binding of signaling molecules (ligands) to receptors capable of triggering signaling cascades into the cell. For example, dopamine is a signaling hormone (neurotransmitter) involved in diverse brain processes (i.e., motor control, emotional response, etc). It is a neurotransmitter that binds to dopamine receptors and then stimulates the enzyme adenylate cyclase in a process that subsequently activates the production of the second messenger cyclic adenosine monophosphate (cAMP). Finally, cAMP acts as an intracellular signal transductor that play roles in many biological processes by transferring into the cell the effects of dopamine.
