Answer:
b. 3,2,4,5,1
Explanation:
3. The action potential induces an electrochemical process that causes release of the acetylcholine.
2. Release of acetycholine into synaptic cleft is down an electrochemical gradient, i.e through diffusion and not requiring energy input.
4. Acetylcholine then binds and activates ligand-gated ion channels of the muscle fiber to open up.
5. Sodium ions will flow into the muscle generation an action potential that will culminate into contractions.
1. The enzyme acetylcholinesterase will breakdown any acetycholine not needed in the synaptic cleft.
They will create all black feathered offspring if both birds are purebreds. If they are both heterozygous, then they will produce a 3:1 phenotypic ratio of black:splashed white feathered offspring.
Topiramate
Topiramate is the drug which might be responsible for this malformation.
Topiramate is an anticonvulsant drug which is taken alone or with other drugs to prevent and control epilepsy. Topiramate is produced in four forms and are all taken by mouth. Topiramate has many side effects which include birth defects if is taken during pregnancy, osteoporosis, vision loss, nervousness and upper respiratory tract infection.
