Answer:
The only way a phenotype or genotype can be recessive is if both alleles are recessive
Explanation:
i think
Answer:It helps an organism reproduce and therefore appears more often. And since dominant alleles sometimes are heterozygous, even if an organism with the dominant gene was able to reproduce, it could still produce a recessive offspring. So I would say that the gene that helps the organism reproduce would actually be the more prevalent trait

Answer:
To keep your body running and fat is used to help process your food
Explanation:
Explanation:
Adipose (fat) cells are specialized for the storage of energy in the form of triglycerides, but research in the last few decades has shown that fat cells also play a critical role in sensing and responding to changes in systemic energy balance.

What ecological impact could a hurricane have on a stable ecosystem?
Answer:
Hurricanes generate strong winds that can completely defoliate forest canopies and cause dramatic structural changes in wooded ecosystems. Animals can either be killed by hurricanes or impacted indirectly through changes in habitat and food availability caused by high winds, storm surge, and intense rainfall.

explain what safety measures you might take to avoid damaging the microscope, microscope slide, or a living specimen on your microscope stage
Answer:
Some of the safety measures one can take to prevent damage to the microscope, microscope slide or living specimen include;
1. Always carry the microscope with two hands
2. Do not touch the microscope lens
3. Clean and store properly after using
Explanation:
1. Microscopes are delicate laboratory equipments and hence, should be handled with care. The proper way to handle or carry a microscope is to place one hand on the arm and the other below the base of the microscope. This will prevent the microscope from hitting something and getting damaged or something falling off.
2. The lens, either the objective or occular, is what makes visibility of any specimen possible. It shouldn't be mishandled by touching it or using inappropriate materials to clean it. A lens cleanser designed for that function should be used.
3. After use, the microscope should be cleaned thoroughly and stored in a dry place. The maintenance of the microscope will improve how long it will last.
The equipments used in the science laboratories require proper handling and safety measures to help the students and researchers to prevent any kind of illness and injury.
• The following are the safety tips to follow to avoid damaging the microscope, a living specimen on the microscope stage, or a microscope slide:
• One should use the microscope with two hands and should wear proper lab clothing.
• One should look at the specimen from the side, not via the eyepiece at the time of turning the low power objective as close as possible to the specimen at the time of the initiation of observations.
• One should avoid the application of coarse adjustment knob at the time of using the high power objective.
• One should prevent turning the fine adjustment knob more than a fourth turn to amend the focus at the time of using the high power objective.
Thus, one should follow precautionary measures while handling microscope and its components.

how does water boiling on a stove represent all 3 types of heat transfer
Answer:
For example, when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.

Snow slides down a mountain in an avalanche. Where would the snow have the
most potential energy?
Answer:
At the top of the mountain
Explanation:
The snow will have the most potential energy at the top of the mountain. Potential energy is the energy at rest of a body. It is a function of the mass, acceleration due to gravity and height of the body.
P.E = mgh
Since at the top of the mountain, we have the highest elevation. So, we expect that at the peak of the mountain the potential energy will be highest here.
What are the
Consequences of rapid
Population growth on
environmental factors?
Answer:
Something that may be affected is habitats.
Explanation:
This is because humans decide to do create buildings and cities because their population is too high, which will make animals lose their habitats due to us chopping trees down or just laying pavement. Another thing that could happen to the environment could be pollution, this affects us all because we all breathe oxygen, so do animals. There are many other things that overpopulation can affect, but that would be too long to state, happy to help though!!! (if you want more info just look up China's pollution levels over the past ten years then look up their population over the past ten years an conpare.)

Phenylalanine is required for the production of many bodily proteins, but none of your cells are capable of synthesizing this essential amino acid. What type of metabolic pathway must be responsible for providing phenylalanine to your cells? How would your diet effect the mount of Phenylalanine that is available?
Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.

A. Pressure caused by high temperatures are balanced by gravity.
B. The sun burns from its core to its surface.
о
C. Forces exerted by orbiting planets cause the sun to rotate.
Answer:
A
Explanation:
The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.
The best explanation of why the sun maintains its size and shape is forces exerted by orbiting planets cause the sun to rotate. The correct option is C.
What is orbiting?"Orbiting" is one of those digital dating terms that perfectly describes what many of us have experienced but didn't realize had a name. It's when someone you were dating tells you they're no longer interested but keeps in touch with you on social media.
The Sun's own weight holds it together and maintains its size and shape. Everything has gravity. In this example, the sun maintains its shape by balancing gravity and pressure.
Planets orbit the sun in elliptical orbits, with the sun slightly off-center of each ellipse.
Therefore, the correct option is C. Forces exerted by orbiting planets cause the sun to rotate.
