1 answer:
Answer:
Explanation:
Autonomic neurotransmitters are the chemicals that are involved in the transmission of the neural signals in tne autonomic nervous system .The autonomic nervous system consist of the sympathetic (adrenergic)and parasympathetic (cholinergic)system and the receptors are alpha,beta and muscarinic ,nicotinic respectively. These receptors are found at various sites and elicit a variety of actions in the body. The main neurotransmitter of the adrenergic system is the epinephrine or non epinephrine and for the cholinergic system is acetylcholine.
All preganglionic neurons use ACh as the neurotransmitter

Answer:
a. all tall
Explanation:
If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.
Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent who is heterozygous will be Tt.
The cross is depicted in the attachment.
Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.
