If u know the water cycle please answer this question
Answer:
Gravity
Explanation:
Percolation is the process of a liquid slowly passing through a filter. It's how coffee is usually made. Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee.
Evaporation-the process of turning from liquid into vapor.
Condensation-water which collects as droplets on a cold surface when humid air is in contact with it.
and gravity- Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Explanation:
Q: Predict and describe some possible effects to your entire food web if the following happened:
A mysterious virus has sickened the secondary consumer fish. There
are few survivors. Fortunately, this virus is not affecting organisms on any other trophic levels. However, the loss of these organisms is
affecting the rest of the food web. Please describe the possible effects:
Answer:
Less fish will disrupt the predators in the ocean. Sharks, and other predators in these oceans need a food source such as fish if this Virus does indeed kill these many fish. Meaning the virus is in this fish, It might spred to predators that eat these fish. Still if the predators of the food chain dont find these food sources for them i am sure they will die of starvation.
Explanation:
If a food source for animals is obsulete i am sure the predators of the animals will have starved to death like how, the Hot blob is affecting the Cassins auklet due to the Less amount of phytoplankton in the oceans.

The correct order of the cells from the outer region of a seminiferous tubule is Spermatogonium > Spermatid > Secondary spermatocyte > Primary spermatocyte.
What is seminiferous tubules?Seminiferous tubules are located in the testes. Meiosis occurs in this region. The process of spermatozoa happens here, and the germ cells are converted into spermatozoa. They are present in large numbers in the lobule of the testis.
The process occurs in steps, and the order of converting the germ cells into spermatozoa is Spermatogonium > Spermatid > Secondary spermatocyte > Primary spermatocyte.
Thus, the correct order is Spermatogonium > Spermatid > Secondary spermatocyte > Primary spermatocyte.

3. Analyze: From the observations you made above, can you state exactly why the aliens
changed their shape? Why or why not?
Answer:
They changed their shape.
Explanation:
The aliens changed their shape because their shapes makes the people frightened. Their shape structure is different from the humans so they change their shape in order to walk among people easily and interact with people which they can't do with their real body structure. So that's why they changed their shape when they interact with people or to walk among people.

A researcher is setting up a randomized clinical trial to evaluate the effect of acetaminophen on liver
function, and designates a control group of subjects and an experimental group of subjects. What could
interfere with the results or completion of this study?
Answer:
Explanation:
Ordinarily, the control group will be the group that has reduced liver function but are provided with placebo while the experimental group will be the group that has reduced liver function and are treated with acetaminophen.
Some factors that could interfere with the results of this trial are
1) Some of the volunteers could have been on some medications before the trial started, that could affect the result of the study because the medications could hamper or improve the liver function or even the performance of the drug (if it is still present in the body system).
2) Some symptomatic volunteers could be using some medications (without the researcher's knowledge) to help alleviate the pain of the reduced liver function. These medications could also affect the result as discussed in the (1) above.
3) Some volunteers could have pre-existing health conditions (that may be known or unknown to them). This could also affect the result of the research as this pre-existing health condition could render the dosage of the drug "ineffective" or even contribute to the deterioration of the liver.
One major factor that could interfere with completion of the study is the availability of patients that will consent to be used as volunteers for clinical trial. Since there are other known/effective drugs for improving liver function, it might be difficult to convince people to consent to this trial thus elongating the completion time of this study
In cats, the allele that causes curled ears is dominant to the allele that causes normally shaped ears. If two hybrid curled-ear cats are mated, what percentage of the kittens is predicted to have curled ears?
Answer:
75% (3:4)
Explanation:
A hybrid organism is one that is heterozygous - it carries one curled allele and one normal allele.
Let's use the letter C. The curled allele is C, the normal allele is c.
The heterozygotes are therefore Cc.
The cross between the two cats is Cc x Cc.
C c
C CC Cc
c Cc cc
Organisms with the genotype CC and Cc are curled ears, since the C allele is dominant to the c allele.
1:4 of the genotypes are CC, and 1:2 are Cc, so 3:4 (75%) have the curled ear phenotype.

Answer:
Proteins made by free-floating ribosome's remain in that cell: whereas, proteins that travel through the endomembrane system leave by secretory vesicles.
Explanation:
A free-floating ribosome creates proteins within cells, but unlike normal ribosomes, this protein is left to float freely in the cell’s cytosol.
Furthermore, proteins that are synthesized in the rough endoplasmic reticulum will most likely be secreted into the extracellular environment.

describe the formation of tissues fluid and lymph
As fluid enters the tissue space from the blood stream pressure builds up in this space and as this hydrostatic pressure increases it causes the interstitial fluid to diffuse into the lymphatic capillaries once the interstitial fluid has entered the lymphatic capillaries it is called lymph
Answer:
Tissue fluid is formed because of the high hydrostatic pressure of the blood at the arteriole end of the capillary that pushes fluid out of the blood.These valves are large enough to allow proteins, which are too big to get into the capillaries, into the lymph vessels.

Explain the reciprocal relationship between human society and limiting factors.
Answer:
A limiting factor is a situation or condition that determines the speed or growth of a certain biological or social process, due to the fact that only a limited amount of it is available.
Therefore, a limiting factor is one that places a limit on the development of a certain characteristic within society. A clear example within biology is the lack of drinking water sources, which is a limiting factor for the development of population settlements, as occurs in the Sahara.
Thus, the existence of limiting factors puts a brake on the unrestricted development of human society, conditioning its development to the adaptation of individuals to the natural conditions of the environment.
Possible Answer:
Human society makes modifications to the environment to suit its needs. Humans can live in large numbers in harsh environments that do not necessarily support the population because of these modifications. Humans cannot, however, change the fact that they are affected by limiting factors. They can change the limiting factors in a specific area, but are still influenced by limiting factors in a larger area, either by region, or globally. Food, water, and energy supplies are limited and will only support a certain human population size. If the human population exceeds this size than disease, famine, and other limiting factors will naturally limit the population size.

Since the 1950s, most mental health hospitals have emptied as a result of the introduction of effective
drug therapies and community-based treatment programs.
drug therapies.
psychotherapy.
community-based treatment programs.
Answer:
Drug therapies and community-based treatment programs
Explanation:
Before the 1950s there was more of an institutionalization approach and they didn't have an alternative for many patients. They had some success with psychotherapy but not nearly as much as we have today. But when they introduced new drug therapies and added community-based treatment programs many mental health hospitals were not filled with patients anymore. Many serious problems were now kept under control with simple pills and a good treatment program.
In the 1950s the mental health hospitals were closed and the patients with mental illness were sent back home to receive the treatments in their communities.
The correct answer is:
Option A. Drug therapies and community-based treatment programs.
The asylums were closed in 1950s as:
Psychotherapy and some institutionalized approaches were present to treat the patients. There were no other alternatives.The incorporation of drug therapies and community-based treatments led to the emptiness of the asylums and therefore, they were closed.The treatments were under control and community-based therapies helped in the treatment of mental patients.Thus, the asylums were closed in the 1950s due to the introduction of drugs and community-based therapies.
Therefore, option A is correct.

Answer:
Water, Sunlight, Soil, and Air
Explanation:
Abiotic factors are the non-living components of an ecosystem. These are physical factors, such as water, sunlight, soil, and air.
In contrast, biotic factors are the living components and include birds and plants.
The way the biotic and abiotic factors interact with one another forms the ecosystem. The biotic factors rely on the abiotic factors to sustain their life.
