Why do cells spend the least time in telophase?
Answer:
Anaphase is the shortest phase of mitosis. In anaphase, the sister chromatids are pulled apart to opposite ends of the cell. In metaphase, chromosomes line up along the metaphase plate.Metaphase takes a short amount of time to complete. Telophase is the next to the shortest phase of mitosis after anaphase.

Which of the following is not true of energy in a cell?
The cell must have energy to maintain homeostasis.
O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.
Answer:
I think is the top one A hope this helps
Cells have a different function it can convert chemical energy to another form of energy to maintain homeostasis, and cells cannot create energy only change the form of energy, hence option b is correct.
What is the energy of the cell?Every cell must continue to check its levels of energy and adjust ATP production rates in line with metabolic demand in order to keep homeostasis.
The ability of cells to sense, and convert nutrients into chemical energy is essential for the continuous fulfillment of this energy demand.
To drive metabolic reactions that would not happen automatically, to transfer necessary substances across membranes, and to do mechanical work, such as moving muscles, cells need chemical energy.
Therefore cells use energy to maintain homeostasis and can change one form of energy into another but can not create energy, hence option b is correct.

Originally, two species of finches lived in the Maldives. One species had long, narrow books for capturing insects from within troes. The other species had larger thicker books for cracking soods. Following an increase in
logging, this ecosystem's population of finches with narrow books began to decline
How does this event support the theory of evolution?
It supports the idea of a common ancestor
Oltillustrates the principle of natural selection
It provides an example of behavioral isolation
It demonstrates analogous structures and evolution
Answer:
I'm thinking maybe B, illustrates the principle of natural selection.
Explanation:
This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.
Answer:
It illustrates the principle of natural selection.
Explanation:
for natural selcection to occur things will change just how the was the finches caught and ate their food

What is the difference between aggression and courtship?
Answer:
How you approach and talk to the person you like
Explanation:
If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand) for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

Describe two problems that occur when a human population grows.
Answer:
Explanation:
The exponential growth of the human population could lead to food shortages, global warming, and other issues of resource scarcity.
Answer:
Explanation:
Unsustainable population growth and lack of access to reproductive health care also puts pressure on human communities, exacerbating food and water shortages, reducing resilience in the face of climate change, and making it harder for the most vulnerable communities to rise out of intergenerational poverty.

Answer:
During the day, the sun heats up both the ocean surface and the land. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse.

How did the peppered moth's environment change, and what caused this change?
Answer:
Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.
Explanation:
The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.
During the Industrial Revolution, pollution darkened tree trunks in England. This favored dark moths, causing a decline in lighter ones.
What are peppered moths?The peppered moth's environment changed due to the Industrial Revolution in England during the 19th century. Prior to the Industrial Revolution, the trees in England were predominantly light-colored, and the majority of peppered moths were also light-colored, or "typica." However, as a result of industrial pollution, the bark of the trees darkened, becoming covered in soot and ash.
This created a selective advantage for the dark-colored peppered moths, or "melanics," who were better camouflaged against the darkened trees. The change in the moth's environment was caused by the burning of coal in factories, which released soot and other pollutants into the air, leading to widespread pollution and industrialization. This phenomenon is often cited as an example of natural selection in action, as the moths adapted to their changing environment through the evolution of their coloration.
