Answer:
Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).
Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.
Explanation:
Answer:
There is 46 pairs of chromosomes.
Answer:
Dogs are inbred for such desirable characteristics as blue eye color; but an unfortunate by-product of such inbreeding can be the emergence of characteristics such as deafness. A 1992 study of Dalmatians (by Strain and others, as reported in The Dalmatians Dilemma) found the following:
38% of all Dalmatians are deaf.
Explanation:
Since the desirable characteristics in the dogs is blue eye color but the unfortunate by product leads to deafness
Answer is: <span>a. True.
</span>The overall effect of insulin is to lower blood glucose and amino acid levels by promoting their cellular uptake and incorporation into glycogen and proteins, respectively. <span>The net effect of insulin is to decrease blood glucose and amino acids and stimulate the cellular uptake of these molecules and their incorporation into polymers.
