The activity of which enzyme decreases in both acidic and basic environments?(1) chymotrypsin (3) cholinesterase
(2) pepsin (4) papain

Answers

I think the correct answer is chymotrypsin. It is the enzyme that decreases its activity when in acidic or very basic environment. This enzyme is derived from bovine pancreas. Its activity is optimal when the pH of the solution is in the range of 7.0 - 9.0.

Which statement best describes a human influence on the biogeochemical cycles?increased eutrophication caused by high levels of nitrogen and phosphorousincreased nitrates available due to inaccurate methods of denitrificationincreased global warming due to alternative energy sources
increased amount of water that is available to freshwater ecosystems

Answers

The best statement would be increased eutrophication caused by high levels of nitrogen and phosphorous. Nitrogen and phosphorous are found in fertilizers. These fertilizers are used by farmers in croplands. Excess use of these might lead for the excess amounts to run off to water bodies which may cause eutrophication. Therefore, altering the nitrogen and phosphorous cycles.

When working muscle cells are deprived of oxygen they produce?

Answers

lactic acid

During intense exertion or activity involving the muscles, there arises a need for a sudden short term burst of energy. This need for energy is so demanding that it cannot be satisfied through the normal mechanism  whereby energy is supplied through aerobic respiration using oxygen.Therefore the muscle cells must rely on other mechanisms that do not rely on oxygen to fuel muscle contraction and this is where they resort to anaerobic respiration which uses pyruvate to play the role of oxygen as the final electron acceptor. In the process, pyruvate accepts an electron and is reduced to lactic acid in the muscle tissues.

Which statement best describes how the evolution of pesticide resistance occurs in a population of insects?A. Individual members of the population slowly adapt to the presence of the chemical by striving to meet the new challenge.
B. All insects exposed to the insecticide begin to use a formerly silent gene to make a new enzyme that breaks down the insecticide molecules.
C. Insects observe the behavior of other insects that survive pesticide application, and adjust their own behaviors to copy those of the survivors.
D. A number of genetically resistant pesticide survivors reproduce. The next generation of insects contains more genes from the survivors than it does from susceptible individuals.

Answers

Answer:

D. A number of genetically resistant pesticide survivors reproduce. The next generation of insects contains more genes from the survivors than it does from susceptible individuals.

Explanation:

Insect populations already have some insects with pesticide resistance genes. Exposure of insects to pesticides results in the natural selection of these insects with pesticide resistance as they are able to survive and reproduce in the presence of pesticides whereas the other insects die. The resistant insects leave more progeny resulting in the evolution of insect population with increased frequency of pesticide resistance gene.

Scientific models must be able to generate ___________.

Answers

Scientific models must be able to generate PREDICTIONS.

Scientific models refers to frameworks, which are used to elucidate and predict the behavior of an object or a system. Scientists usually use models to carry out research and to explain the results of their research. A good and effective scientific model should be able to make accurate predictions.
