The zebra mussel arrived in the United States in 1985 on the ballast of a ship. Since this time, it has spread rapidly throughout the waterways of the eastern U.S. and parts of Canada. Which of the following statements is NOT true about how the waters of the United States contributed to the success of the zebra mussel? They contained an abundance of prey for the zebra mussel.
They contained toxins or pollutants that eliminated natural competitors of the zebra mussel.
They contained few or no natural predators of the zebra mussel.
They contained few or no natural species occupying the niche filled by the zebra mussel.

Answer 1

Answer:

Answer:

They contained few or no natural species occupying the niche filled by the zebra mussel.

Explanation:

All the available options are capable of contributing to the success of the zebra mussel in the United State water.

However, it is not true that the United State water contained few or no natural species occupying the niche filled by the zebra mussel. The zebra mussel are exotic species that got into the United State water around 1991 and were able to outcompete the native species and multiply rapidly, a characteristic of an invasive species.

Abundance of prey for the zebra mussel will ensure that their population thrives due to adequate availability of food.

The presence of toxins or pollutants that eliminate natural competitors of the zebra mussel will enable their population to thrive due to lack of competition for resources, provided the toxins/pollutants are not toxic to the zebra mussels themselves.

The presence of few or no natural predator will also enables the population of zebra mussels to thrive because that is another limiting factor removed.

Answer 2

Answer: The answer is most likely the second choice. All answer choices could be possible, but in light of the others the second choice is far too specific, and there is no information in the prompt to even indicate that as a plausible answer choice.

A wildlife biologist suggests re-introducing the eastern cougar into southern Alabama, reasoning that besides bears, which can survive off of berries and grubs, there are no large natural predators, and that it would be good for the food chain. It is assumed that the eastern cougar would eat deer, which in turn, graze on tree bark, shrubs, and leaves. The average cougar weighs about 100 pounds, as does the average deer. The average cougar has a range of one square mile. A recent biological study showed that there were about 16 deer per square mile in Alabama, an average about 40,000 pounds of vegetation per square mile, and an average of 9.5 people per square mile in southern Alabama. Despite the biologist's proposal, other biologists vote against re-introducing the cougar. Which of these is a possible VALID reason for this?

A cell is viewed under a microscope and is found to have two nuclear envelopes and spindles that appear to be breaking apart. Which phase of mitosis is the cell most likely in?a. Telophase
b. Anaphase
c. Metaphase
d. Prophase

Answers

c. Metaphase

The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.
