An experiment was conducted in which a purified protein from the body was exposed to a solution high in urea, and its tertiary structure was lost. When it was removed from the solution, the protein regained its original structure. Which of the following describes what is occurring when the protein is exposed to the solution high in urea?

A The side chains of the protein react with the urea, breaking bonds, which causes a conformation change.
B The sequence of amino acids rearranges in a toxic environment, which causes a conformation change.
C Urea reacts with the side chains of the protein sequence that causes a conformation change.
D The side chains of the protein react with urea, forming new bonds that cause a conformation change.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
