Question: The blades of a windmill turn on an axis that is 40 feet from the ground. The blades are 15 feet long and complete 3 rotations every minute. Write a sine model, y = asin(bt) + k, for the height (in feet) of the end of one blade as a function of time t (in seconds). Assume the blade is pointing to the right when t = 0 and that the windmill turns counterclockwise at a constant rate.
Answer:
a is the length of the blade.
The vertical shift, k, is the height of the windmill.
a = 15
k = 40
The period is 20 seconds.
b = pi/10

The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
Red blood cells (RBCs) are unable to replace damaged proteins because they lack a nucleus and organelles, including mitochondria. Instead, new RBCs are constantly produced in the bone marrow to replace damaged or aged ones. When RBCs are damaged or aged, macrophages phagocytize them.
Red blood cells (RBCs) are unable to replace damaged proteins because they lack a nucleus and organelles, including mitochondria. This means that RBCs cannot synthesize new proteins to replace damaged ones. Instead, RBCs have a limited lifespan and are constantly being replaced by new RBCs produced in the bone marrow. When RBCs are damaged or aged, they are phagocytized by macrophages in the spleen, liver, and bone marrow.

Answer:
The answer is D: It is a way to camouflage the squirrel in a changing habitat.
Explanation:
There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.
