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).
Hello :)
So first the glycolysis process is the process when a glucose molecule is broken down by enzymes in order to make pyruvate, this acid provides energy to cells.
So, now since we know what glycolysis is, we know that it breaks down glucose which is indeed basically sugar.
Therefore the answer here would be 4. simple sugars.
Answer:
Negative inducible.
Explanation:
Operon may be defined as the cluster pf genes that are expressed by the single RNA polymerase. The operon includes in the example of the the polycistronic genes.
Negative inducible operon includes the binding of regulatory protein with the DNA and inhibits transcription. The regulatory protein binds with the operator that prevents RNA polymerase transcription. The mutation in the negative inducible operon prevents the binding of repressor to the small molecule.
Thus, the correct answer is option (a).
The genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.
<h3>What is a dominant genotype?</h3>
A dominant genotype is a set of gene variants characterized to have dominant alleles that mask the expression of recessive alleles in heterozygous individuals in cases of complete dominance.
In conclusion, the genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.

Biomass is the total mass of a specific organism in the area. If there is a negative value of change in shoot biomass, that mean the mass of the shoot in this period are less than before. This indicate increases in predation/death which reduce the population of the shoot more than its growing rate. The cause could be an increases in predator population or decreases in food/resource.
