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).
Prokaryotic cells do not have a nucleus, animals cells have a nucleus and plant cells have a nucleus. Animal cells and plant cells are both eukaryotic.
Electric motors transform electrical energy into mechanical energy so the answer would be B.
Explanation:
Answer:
The new pressure of this gas is 30 atm.
Explanation:
According to the Boyle's law, pressure of a gas is inversely proportional to its volume. It is given as :
Here,
So, new pressure of this gas is 30 atm.
