Investigating cricket will reveals that some specie of the insect produce a song by rubbing their legs or wings against each other. In those specie that sing only the male insect produce songs.
This observation can be taken to mean that the male song is a potential form of communication to potential mates.
Answer:
Plasmids
Explanation:
The cellular components are important in the production of the protein luciferase. The protein is produced by the reaction in the silk worms and the fireflies. In addition, the protein in addition, the correct sequencing is essential in the coding of the protein. The concentration of the protein in the cytoplasm makes the control of the production of the protein feasible under feasible conditions.

Answer:
TFH cells in the germinal center
Explanation:
The Tfh cells, present in the germinal center, are responsible for maturing and stimulating the class change of immunoglobulins (such as the change from IgM to IgE). This change could stimulate the new classes of immunoglobulins to act with stimulating antibodies to produce an immune response.
It is important to point out that the germinal center is the activated point of a lymphoid follicle that contains B and T lymphocytes, which act in the memory of the cells of the immune system.
Answer : The reason is Osmosis.
Explanation :
Osmosis : It is a type of process in which the movement of particles occurs from its high concentration to low concentration through the selective semi-permeable membrane.
From the given image we conclude that the molecule A diffuses across the membrane but molecule B do not due to the osmosis. That means the selective semi-permeable membrane allows only molecule A through it.
Hence, the reason is Osmosis.
