They are better because they are for comparative use for instance hair color to finger nails they both grow but onto separate parts of the body.

The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.
Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed in isotonic plasma in which case water movement into the cell is equal to water movement out of the cell and so the cells remain intact.
Answer:
Lateral Hypothalamus
Explanation:
According to the hunger researchers' initial assumption lateral hypothalamus is that part of the brain which regulates intake of food and metabolical activities like metabolical regulation of peptides like the orexins melanin-concentrating hormone. It is that part of the brain that plays a key role in the ingestive behavior regulation.
The lateral hypothalamus system initiates physical and cognitive processes like it promotes arousal and feeding behavior, metabolism, regulates body temperature, BP, etc. and when stimulated it results in the feeding behaviour in animals as they begin to eat.
Answer:
homeostasis is the state of steady internal physical and chemical conditions maintained by living system.
Diffusion is an important process for living things; it is how substances move in and out of cells.
Diffusion helps maintain homeostasis by creating specific concentrations of molecules inside the body compared to outside and Cells in homeostasis are successfully maintaining the internal conditions necessary for basic functioning
The cell needs to export waste and other molecules, and import fuels and fluids. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.
