At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas, whereas ionic compounds exist only as solids, Ionic compounds exist in stable crystalline structures. Therefore, they have higher melting and boiling points compared to covalent compounds.
After the adenylyl cyclase reaction (which convert ATP into cyclic adenosine monophosphate-cAMP), cAMP level is directly increased. Next steps of PKA activation include:
• cAMP binding to regulatory subunits of PKA, as a result conformational change in the regulatory subunits of PKA is induced,
• catalytic subunits are detached and unleashed by regulatory subunits and as a result activated.
“A daughter looks different
from both her mother and her father” best illustrates the result of the
process of meiosis.
Meiosis<span> is a type of cell division that reduces the
number of chromosomes in the parent cell by half and produces four gamete
cells. This process is required to produce egg and sperm cells for sexual
reproduction.</span>
The correct answer between all the choices given is the

The right option is Courtship
Courtship is a behavior in which different
species interact and select their partners for mating which leads to
reproduction. Most times, the female specie chooses the desired male to mate with before
copulation. Various behaviours such as display
of strength, dancing and vocal utterance are often used during courtship. For the question given above,<span>the type of behavior displayed by the species of balloon flies is an example of courtship.

Answer:
See the answer below
Explanation:
For each heterozygous parent with the genotype BbRr, the possible gametes are: BR, Br, bR, and br. A set of these gametes from one of the parents will be lined up along the top of the Punnet's square while another set from the other parent will be lined up along the side of the square.
The result is shown in the attached image.
