Answer:
the total entropy of an isolated system can never decrease over time.
Explanation:
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time. The total entropy of a system and its surroundings can remain constant in ideal cases where the system is in thermodynamic equilibrium, or is undergoing a (fictive) reversible process.
Hope this helps!!
Answer:
A
Explanation:
in DNA there is complementary base pairing which is that Adenine always pairs with Thymine and Cytosine always pairs with Guanine. therefore, if there is a certain amount of adenine in the DNA it must have the same amount of its complementary base, thymine.
the answer cannot be b as cytosine and thymine are not complementary base pairs. although b can coincidently be correct- that the amount of cytosine and thymine are equal- the question states that it must always be true. the answer cannot be c as ribose is found in RNA and deoxribose is found in DNA.
I think that both the dialysis tubing and the small intestine are selectively permeable. Which means they allow only some and not all materials to pass through; for example; glucose which is a simple molecular sugar; will pass through, however larger molecules such as starch can not pass through. A dialysis tube is a semipermeable membrane that allows molecules of certain size to get in or out, while keeping molecules above that size in. They are often used to remove impurities from preparations of proteins or other macromolecules and also to normalize pH of a preparation.
The process of heat acclimatization requires tolerance of gradually increased activity in the hot environment. A healthy individual that is well adapted to the body’s physiological changes is said to have an improved heat tolerance. Heat acclimatization is extremely useful for athletes.

A person who studies Natural History
Explanation:
Natural History is the history of organisms. This includes, animals, plants (fungi too) in their natural environment.
