Answer: Most of the beetles will be brown because they have a higher likelihood of reaching reproductive age.
Natural selection is the process of selection by nature in which an individual organism exhibiting more favorable phenotypic characteristics has more chances of survival and reproduction in it's corresponding environment.
In the new environment, brown beetles can camouflage themselves from predators better than the green beetles and blue beetles can. This is because of the fact that brown color of beetle is a better phenotypic trait which favors the survival of brown beetles over green and blue color. Therefore, the survived brown beetles will reproduce and grow in number.
Answer: (B) Paracrine signaling
Explanation: Paracrine signaling occurs between cells that are relatively within a short distance apart. The signaling triggers quick responses and can last only for a short period of time because of the wearing-off of the paracrine ligands (neurotransmitters).
Cells that exhibit paracrine factors release them into the immediate extracellular environment.
The cellular components of blood are : B. RBC , WBC, and platelets

WBC / white blood cells : Responsible in maintaining immune system
Platelets : Prevent Bleeding
