Pressure and Volume are directly related to the temperature of a substance
Answer:
Blood Brain Barrier(BBB)
Explanation:
This is a biological interface of special endothelial cells of astrocytes, pericytes , capillaries, neurons and other structures, acting as a physical barrier or gate separating the Central Nervous system from the peripheral blood circulations. Thus it formed a tight junction serving as a physical barrier to selectively regulate the entrance of substances from the cerebral blood flow into the brain, therefore maintaining homeostasis of the brain.
From above any substances absorbed into the blood stream irrespective of the mode of entry are transported through the BBB, and are selectively regulated to enter the brain cells by the BBB's interactions with the blood vessels, hormones etc.
Basically it allows the passage of nutrients, a few drug, hormones and resists certain toxins and pathogens for the brain homeostasis.
Answer:

The appropriate response is Toxicity. A toxic substance is a substance that can be toxic or cause wellbeing impacts. Individuals are for the most part worried about chemicals like polychlorinated biphenyls and dioxin which can be found at some perilous waste destinations. Any synthetic can be lethal or destructive under specific conditions.
Your answer would be C as a physical change is characterized as a change in physical appearance be it shape, phase, or size. A good example is an ice cube when it melts, it may look different but its chemical composition is the same and the change from is ice to water is reversible unlike a chemical change like baking a cake which cannot be reversed to its original state before it went into the oven. Hope this helps!
