Answer:
The pressure is so great at the inner core that it causes atoms to push together.
Explanation:
The inner core of Earth remains solid even though it is very hot because the pressure is so great at the inner core that it causes atoms to push together. This is present in the second option.
What are the different layers of the earth?The earth has three layers, such as the inner hot core, the mantle, and the last outer crust, and the temperature of each layer is varied and made up of different compositions. The outer crust has different minerals as the mountains, plants, and animals present there, while the molecules are not present under the high pressure here. The middle layer, known as the mantle, is composed of iron and other elements, whereas the inner core is hot and solid due to high pressure.
Hence, the inner core of Earth remains solid even though it is very hot because the pressure is so great at the inner core that it causes atoms to push together, so the second option is the correct answer.

has long, snowy winters. Some of the wolves have an allele that gives them white coats. This makes them
better able to sneak up on prey. Is this an example of natural selection? Explain.
Answer:
Yes
Explanation:
Natural Selection is not only when genes and alleles are passed down to children but also when your genes better adapt to your surroundings and the environment this shows natural selection
Why is biomass a better alternative to oil?
A. Biomass does not release carbon dioxide.
B. Biomass creates radioactive waste.
C. Biomass does not need to be burned.
D. Biomass is a renewable resource.
Answer:
D
Explanation:
Biomass does release CO2 (when burned) because it is organic - contains carbon compounds.
Biomass does not create radioactive waste.
Biomass is renewable because it comes from plants, whereas oil takes millions of years to make, so it is non-renewable.
The correct option is (d) Biomass is a renewable resource.
Because it can be created from sources that are renewable and can be continuously replenished, such as garbage and plants, bioenergy, also known as energy obtained from biomass, is a sustainable substitute for fossil fuels. And cut down on our gasoline supply, compromising our national security.Some of the advantages of biomass energy are:-A constant and accessible renewable energy source is biomass.It has no carbon emissions.It lessens our dependency on fossil fuels.Is more affordable than fossil fuels.The generation of biomass gives manufacturers a new source of income.Fewer trash items in landfills.Learn more about advantages of biomass energy brainly.com/question/11381203

How does oxygen concentration in the atmosphere correlate with animal diversity?
Answer:
Oxygen burns the food within their bodies and releases energy for various activities and thus it helps animal to be alive. to use it in respiration. Animals need oxygen (O) to survive. In fact, all organisms need oxygen to complete the process to burning glucose for fuel.

Which molecules contain only carbon, hydrogen, and oxygen?
Select all that apply.
carbohydrates
glucose
proteins
O nucleic acids
[tex] \huge \purple{\tt{Answer:}} [/tex]
glucose
The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.
What is glucose?Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.
It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.
Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.
Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.
Thus only glucose is composed of oxygen, carbon, and hydrogen.
Therefore the correct option is B.

B. Asexual reproduction has 1 parent with identical offspring
C. Asexual reproduction has 2 parents with similar offspring
D. Asexual reproduction has 2 parents with identical offspring
Answer:
A.)
Explanation:
We know that asexual means one. In this case, it would be A
., because there is one parent producing the cells. There may be some differences, which would make similar offspring, not identical offspring. So the answer would be A.) :) Hope this will help!

A. temperate woodland
B. temperate rain forest
C. tropical rain forests
D. savanna
A biome that has a large amount of rainfall, high temperature, and poor soil is a Tropical rain forests. So, the correct option is (C).
What are Tropical rain forests?Tropical rainforests are defined as rainforests that occur in areas of tropical rainforest climate with no dry season when all months have an average rainfall of at least 60 mm. It can also be called lowland equatorial evergreen rainforest.
The largest rainforests exist in the Amazon in Brazil (South America), the Democratic Republic of the Congo (Africa) and Indonesia (South East Asia). They are also found in Hawaii and on islands in the Pacific and Caribbean.
Vegetation is characterized by large trees and dense vegetation on the ground surface, but due to the high amount of rainfall and the rapid acquisition of nutrients from the decomposition of organic matter by plants, soils in tropical rainforests are generally nutrient deficient and non-porous.
Thus, a biome that has a large amount of rainfall, high temperature, and poor soil is a Tropical rain forests. So, the correct option is (C).

Which of the following would change the allele frequencies of a population?
A)Lack of mutation in the DNA
B)Mating is random with no selection occurring
C)A population on an island remains isolated and no one leaves or moves on the island
D) All of the answer choices would change allele frequencies of a population.
Answer: option B.
B)Mating is random with no selection occurring
Explanation:
This will cause change in allele frequency because it's a genetic drift which is the change in the frequency gene variant that is common in a population due to random sampling or random mating. When this occur it lead to a change in percentage or incidence of gene variant in a population since there is random sampling without any selection.
Mating is random with no selection occurring, which would change the allele frequencies of a population.
What would increase the allele frequency in a population?Natural selection can drive microevolution, or a difference in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations.
Thus, option"B" mating is random with no selection occurring.
