Answer:
increases; protein denaturation occurs
Explanation:
One of the characteristic of enzymes is the sensitivity to temperature .
Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.
However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.
At temperature above the optimum,the high temperature breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be denatured
Answer: D. A river separates members of a squirrel population that used to occupy the same geographical area.
Explanation:
Allopathic Speciation occurs when a geographic barrier (river, mountain, or canyon) separates members of a population

Answer: Chromosome
The polynucleotide DNA strands are wrapped on circular proteins called histones which then are condensed into a structure called chromosome.
Methylphenidate refers to a CNS stimulant mainly used in the treatment of ADHD (attention deficit hyperactivity disorder) in children between the age of 6 to 12, adults up to the age of 65, and adolescents. It can also be used in the treatment of narcolepsy.
However, the application of the drug may also bring some side-effects with it. Some of the common side-effects related to medicine are decreased appetite, headache, hallucinations, sweating, fever, dizziness, increased heart rate, weight loss, and others.
In the given case, due to the application of the drug, the child is having hallucinations. Thus, in the given case, the nurse should recommend the client to report the manifestations as quick as possible, and discontinue the use of medicine.
False because extrusive rocks have fine-grained texture due to the rapid cooling of magna above the earth surface. On the other hand extrusive rocks have course grained texture due to slow cooling of magna beneath the Earth's surface
