A lake is home to a large number of trout. Identify what is most likely to happen if a chemical is dumped into the lake.
I. The trout will not be affected by the pollution.
II. The number of trout will increase.
III. The trout will suffer from disease.
A) I
B) I and II
C) III
D) II and III
Answers
Answer: C
Explanation: The process that occurred in the lake is natural selection. In the presence of an external environmental influence such as pollution, only the trouts that were fit to survive or in other words those that have the alleles that help in adapting to the new conditions live and increased in numbers. In such a case, one can say the fittest of the organisms survived and the corresponding allelic frequency in that population increased over time. The organisms carrying the other alleles died due to pollution and hence the overall frequency of alleles change.
A lake is home to a large number of trout the trout will suffer from disease is most likely to happen if a chemical is dumped into the lake. The correct option is C.
What is chemical pollution?Chemical pollution is the contamination of our environment with chemicals that are not naturally present.
According to scientific evidence, the trout in option will most likely suffer from disease.
Chemical pollution can harm aquatic life, including fish, by lowering oxygen levels, changing the pH balance of the water, and introducing toxins into their food chain.
Exposure to such chemicals can weaken the fish's immune system, making them more vulnerable to disease.
Option B and A is also less likely to be true because the introduction of chemicals into the water can disrupt the ecosystem's balance and affect the availability of food and oxygen, causing the trout population to decline.
Thus, the correct option is C.

A. Describe the difference between gradualism and punctuated equilibrium.
B. Describe the conditions under which new species may arise.
C. Explain the difference between allopatric and sympatric speciation.
D. Describe the role of prezygotic and postzygotic barriers in the process of speciation.
Answers
A. Both theories describe the rates of speciation. For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change.
B. New species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed.
C. Allopatric speciation occurs when two species are living in separate environments and therefore there is no gene flow between the populations. ... Sympatric speciation occurs when two species are living in the same environment.
D. Reproductive isolation is a mechanism that keeps species from mating with others. Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring. ... Postzygotic mechanisms include hybrid inviability, hybrid sterility and hybrid "breakdown."

Write a 2 sentence summary about cellular respiration.
Answers
Answer:
I looked it up and this what it said
Explanation:
"Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport."
Cellular respiration can be summarized as:
What is cellular respiration?Cellular respiration is the mechanism by which living cells break down glucose molecules and release energy in the form of ATP molecules.
Energy coupling can be seen in cellular respiration.
Glucose is broken down in an exothermic reaction and the energy released powers the endothermic reaction of ATP generation.
Glycolysis, the TCA cycle, and the electron transport chain are the three steps of cellular respiration.
From one molecule of glucose, 38 molecules of ATP are created in all three stages of cellular respiration.

How does artificial selection differ from natural selection? Choose all that apply.
O During artificial selection, the mating pairs are selected by humans, not the organisms.
O The outcomes of artificial selection are predictable.
O Artificial selection requires variety in a population.
O Artificial selection does not help a population adapt to its environment.
Answers
Answer:
All answers should be selected.
Explanation:
Artificial selection means humans select the mating pairs which makes the outcomes predictable. Variety is required because it is how humans can "customize" the traits of an organism. However, it does not help a population adapt to its environment because these traits are made for human satisfaction, not the survival of an organism.

Which of the following statements is true?
Fusion reactions split hydrogen nuclei apart.
Fission reactions release more energy than fusion reactions.
Nuclear power plants change electricity into nuclear energy.
U-235 is an isotope of uranium.
Answers
Answer:
Fission occurs when a neutron slams into a larger atom, forcing it to excite and spilt into two smaller atoms—also known as fission products. Additional neutrons are also released that can initiate a chain reaction.
When each atom splits, a tremendous amount of energy is released.
Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control.
The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.
