Which statements describe aspects of what causes wind to blow? Select two options.
Answer:
statements describe aspects of what causes wind to blow is Wind is caused by differences in air pressure. Explanation: Due to different rate of heating and cooling of air there is difference of the air pressure on the surface of the land.Apr 10, 2020
Answer:
The Correct Answer is A and C.
Explanation:
The wind is the movement of air, the movement of air is happened by the difference in pressure.
A difference in air pressure is what causes the wind to blow. Difference in pressure is happened by the uneven heating of the earth's surface.
The wind is normally moving air from a high air pressure place to a low air pressure place.
The greater the difference in air pressure the stronger the wind blow.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.
Answer:
Yes, it is possible.
Explanation:
In this case, I'm guessing you mean breeding.
If that's the case, they will form hybrids.
Between two different species, inter specific hybrids will be formed.
Between two different genus, intergeneric hybrids will be formed.
There's even rare cases of breeding between two families.
So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.
So to answer your question, it is possible.

If an IV has 4% salt, and the patient's cells have 6% salt are the patient's cells hypotonic, isotonic, or hypertonic compared to the IV?
Answer:
The correct answer is - hypertonic.
Explanation:
Hypertonic solution or the cells consist high concentration solutes in comparison to the other solution and in such cases, the water tends to move from hypertonic region to the hypotonic region.
In the given case the salt concentration which is solute in the patient's cells is higher 6% than the salt (solute) concentration of the given IV which is 4%, therefore, the patient's cell is hypertonic in comparison to IV.

what are water and carbon dioxide in the cellular respiration reaction
Answer:
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What relationship exist between amino acid and protein?
Explanation:
When connected together by series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on other interactions (dashed lines) between its amino acid side chains.
Amino acids are the subunits or monomers of proteins i.e. proteins are made up of amino acids.
WHAT ARE PROTEINS?
Proteins are one of the four major biological molecules in nature. Proteins are polymeric compounds made up of long chains of structures called AMINO ACIDS. Amino acids come together in a chemical reaction called CONDENSATION REACTION to form complex protein molecules. Each amino acid is linked to one another by a covalent bond called PEPTIDE BOND. Peptide bond is a kind of covalent bond that links two amino acids together. It forms between the amino group (-NH2) of one amino acid and carboxyl group (-COO) of anotherHence, amino acids are monomeric units of protein molecules.

What are the effects of fishing on the reef ecosystem
Answer:
Coral reef fish are a significant food source for over a billion people worldwide. Many coastal and island communities depend on coral reef fisheries for their economic, social, and cultural benefits. But too much of a good thing can be bad for coral reefs. Download this infographic | Infographic Text
Coral reef ecosystems support important commercial, recreational, and subsistence fishery resources in the U.S and its territories. Fishing also plays a central social and cultural role in many island and coastal communities, where it is often a critical source of food and income.
The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations. Such losses often have a ripple effect, not just on the coral reef ecosystems themselves, but also on the local economies that depend on them. Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats.
Coral reef fisheries, though often relatively small in scale, may have disproportionately large impacts on the ecosystem if conducted unsustainably. Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.
scientists have discovered several species of insect that all contain the same DNA sequence on their second chromosome. What does this evidence suggest?
how do scientists know living things are related to eachother? (there are two way)
Answer:
scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.

Story #1
Once upon a time, there lived a population of mountain people whose members all had wings but different
types-either bat wings or bird wings. 40% of the population had bat wings and 60% of the population had bird
wings. One day, a storm hit that lasted for several weeks. Those with bat wings were able to fly around and
find food because their wings were water resistant, while those with bird wings were not able to get food
because their feathers were not water resistant and got soaked through. Many of the bird-winged people starved
and did not survive, so their alleles decreased in the gene pool, lowering the frequency of the bird wings in
future generations. Over many generations, the environment had more and more long periods of rain and the
genetic makeup of the population shifted to 10% with bird wings and 90% with bat wings.
What is the trait being described?
What are the variations that exist in this population?
3. How did the event lead to the change in allele frequency?
Alleles?
4. What type of evolutionary mechanism did this story show?
5. Was there an adaptation in this story? If so, identify it.
6. Did the change make the population more or less similar to other populations?
7. Would this increase or decrease reproductive isolation?
Increase or decrease speciation?
8. Did the new population change for the better, worse, or have no effect? Why?
Answer:
The trait being described is the ability to fly in rainy season.
Explanation:
The trait being described is the ability to fly in rainy season. The people with bat wings and people with bird wings are present in the population. The event lead to the change in allele frequency because the population of people with bird wings die due to starvation. Yes, the bat wings were adapted to that environment so they are able to survive. The change make the population less similar to other populations because population of people with bat wings increases as compared to other population. Yes, the new population change for the better of the ecosystem because the population is able to controls the population of other species in the ecosystem.
S. If cells of onion peel and RBC are separately kept in hypotonic solution, what will take place? Explain the reason for your answer
Answer:
Well for the onion peel, since its a plant cell...it shall gain water from the solution as it has a lower water potentail,and hence increase in size, becoming turgid and tight, with the cell wall exerting pressure to stop it from bursting.
For the RBC, its an animal cell, and shall also gain water, but since there is no cell wall to support it, it shall soon gain so much water that it shall burst becuase of the pressure, through lysis, and shall die.
Note, the plant cell does not die.

Explain why NON-RENEWABLE resources are NOT renewable even though plants and animals continue to die all the time.
Answer:
The correct answer is - these resources take million years to be replenished.
Explanation:
Non-renewable resources are the resources that come from a source that will finish ultimately or run out or can not be replenished in one or more human life cycles. These sources might take million years to replenish.
Most non-renewable resources are fossil fuels, coal, natural gas. Fossil fuels, cols are were formed as the remains of dead plants and animals but takes millions of years to decay, under huge amounts of pressure and heat.

C. Unicellular organisms
D. All of the above
rion
таасан
Answer:
The sperm cells.
Explanation:
Liver cells, sperm cells and unicellular organisms all undergo meiosis. Therefore, the correct option is D.
A specific cell division known as meiosis occurs in sexually reproducing organisms. The cells produce gametes through this process, which are the specialized sex cells used in sexual reproduction. Despite not being directly involved in reproduction, liver cells can undergo meiosis. Under certain circumstances, meiosis in liver cells can be induced to form haploid cells.
Male gametes, or sperm cells, undergo meiosis as part of spermatogenesis. Haploid sperm cells with half the number of chromosomes than the parent cell are formed during meiosis in the testis. Depending on their reproductive strategies, unicellular organisms may also undergo meiosis to produce haploid cells that can mate with other haploid cells during sexual reproduction.
Therefore, the correct option is D.
