Imagine two North American ground cricket species that contact each other as the southern species moves northward during a perio

d of global warming. These two species do not mate much, due to differences in their courtship songs. The northern cricket does not seem to tolerate the warmer temperatures well but is limited in its ability to move north because it does not normally disperse much. Based on this information, which is the most likely outcome?
A) a behavioral reproductive isolating mechanism
B) a prezygotic isolating mechanism
C) a postzygotic isolating mechanism
D) a gametic reproductive isolating mechanism
E) two of the above

Answer:

A behavioral reproductive isolating mechanism.

Explanation:

Isolating mechanisms may be defined as the mechanism that do not allow the different species to mate with each other. Two main isolating mechanisms are prezygotic isolating mechanism and a postzygotic isolating mechanism.

The behavioral isolating mechanism is a type of pre zygotic reproductive isolating mechanism in which the species are unable to meet with each other due to the differences in their courtship behavior that includes different sounds and color. The cricket species is unable to meet with each other due to difference in their courtship behavior.

Thus, the correct answer is option (A).

In the disease myasthenia gravis, the human body makes-by mistake- antibodies to its own acetylcholine receptor molecules. These
andre [41]

Answer:

Muscle contraction function.

Explanation:

The nerve endings possess synaptic acetylcholine vesicles ready to be released. The action potential depolarizes the presynaptic terminal and increases the concentration of axoplasmic calcium; Acetylcholine molecules are thus released, so that the concentration of the neurotransmitter at postsynaptic (nicotinic) receptors is temporarily increased. This is followed by post-synaptic membrane depolarization, muscle membrane action potential with increased rnioplasmic calcium concentration, and finally muscle contraction. Acetylcholine is hydrolyzed by acetylcholinesterase and resynaptic at the presynaptic level by cholinecetyltransferase. The etiopathogenesis of myasthenia gravis is autoimmune and there are antibodies against acetylcholine receptors that circulate in the blood, as well as a decrease in the number of receptors on the motor plates, that is, it is produced by the postsynaptic blockage of the myoneural plaque, that generates fatigue and localized or generalized muscle weakness that is characterized by the worsening of the contractile force of the muscle.
