I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
Answer: Option B) Lipids generally don't dissolve in water.
Explanation:
All lipids are small biomolecules that are insoluble in water but dissolve readily in nonpolar organic solvents, and contain fatty acids, sterols. So, not all lipids are made of fatty acids and glycerol, and the chemical properties of each lipids depends on their composition.
Thus, all lipids share the characteristics of not dissolving in water.

Answer:
Animals takes oxygen inside their body from the environment in order to survive..
Explanation:
Animals takes oxygen inside their body from the environment and exchange of gases occurs in the organ such lungs where the cells loaded itself with oxygen and removed the carbondioxide from the cell. When the organism exhaled carbondioxide gas is released in the environment. Food is broken down in the digestive tract and nutrients is absorbed from small intestine which adds these nutrients into blood that is used by the cells. Kidney filters the blood and removes the nitrogenous waste and excess amount of water from the blood. This urine is removed with the excretory system of the body.
