How does mitosis in plant cells differ from that in animal cells? A. Plant cells lack spindle fibers.
B. Plant cells lack centrosomes.
C. Animal cells lack cytokinesis.
D. Animal cells lack a cell plate.

Answers

I think the correct answer from the choices listed above is option D. Mitosis in plant cells differ from that in animal cells in the sense that animal cells lack a cell plate. In plants cell division takes place through cell plate formation because constriction is not possible due to presence of hard/rigid cell wall.
I believe the correct response is D. Animal cells lack a cell plate.

When you viewed the plant cells, adjusting the nose piece made corrections to the ____________ while turning the fine focus knob made adjustments to the ________. Select one:

A. magnification, resolution
B. resolution, magnification
C. sample size, clarity
D. clarity, sample size

Answers

Answer: Option A; magnification, resolution

Explanation: Nose piece does the changes in the position of objective lens, and the function of objective lens is to magnify the sample. So the first blank is magnification. Fine knob makes the image look sharper, which means its resolution is adjusted. So the second blank is resolution. Sample size does not affect the sample observed through a microscope. Thus, option C and D are incorrect.

What happens to the phosphates when plants and animals die?

Answers

Answer:

When plants and animals die, organic molecules also undergoes decomposition and this causes the incorporated phosphates to go back to the soil or bodies of water.

Explanation:

Phosphates are naturally related to "phosphorus." They play a vital role in the life of animals and plants. Phosphorus can be commonly be found on the earth's land and water (although the land has a smaller amount of it). Plants naturally absorb phosphate from where they're growing. Animals take up phosphates by eating plants. The phosphate that plants get from the soil are considered inorganic. They only become organic when it is incorporated into the plants DNA (since this is an organic molecule).

So, this means that if there's a sufficient amount of phosphate, there will be more plants on earth as it is also important in the process of acquiring nutrients.

When animals and plants die, all of the organic molecules such as phosphate also breaks down and thus, it falls back to the soil or bodies of water. Then, they are ready to enter another Phosphorus cycle.

When animals and plants die, phosphates will return to the soils or oceans again during decay. After that, phosphorus will end up in sediments or rock formations again, remaining there for millions of years. Eventually, phosphorus is released again through weathering and the cycle starts over.

A particular species of fish were split by the formation of the Isthmus of Panama a long time ago. The fish developed changes in their genes to adapt to the new environment and became two different species. What is this process called?

Answers

This is speciation. In this process, two distinct species are formed through the intervention of some means such as differing environments or locations. This is done typically as a way of staying evolutionarily competitive in the area in which the species resides. The new species would be the exemplar of that which is best suited to the new conditions.

Answer:

Allopatric Speciation
