Which best explains how coal deposits formed?
A. Millions of years of pressure and heat turned decaying animals
and plants into coal.
B. Natural gas solidified underground, creating coal.
C. Heat from the sun transformed decaying animals into coal over
millions of years.
D. Dead plants compacted underground for hundreds of ylaars
eventually turned into coal.
Answers
Answer:
A: Millions of years of pressure and heat turned decaying animals and plants into coal.
Millions of years of pressure and heat turned decaying animals and plants into coal. Therefore, option (A) is correct.
What is coal?Coal is a fossil fuel that is formed from the remains of ancient plants and animals that have been buried and subjected to high temperatures and pressure over millions of years. As layers of sediment and rock accumulate over time, they compress the organic material and trap it beneath the Earth's surface.
Over time, the heat and pressure cause the organic material to break down and undergo a series of chemical changes, eventually forming coal. This process is known as coalification and can take millions of years to complete.

As water passes into the guard cells, the pore opens. explain why.
Answers
Answer:One of the most important functions of guard cells is to control the closing and opening of the stoma/pores. While the opening of these pores allows water to be released into the environment, it also allows carbon dioxide to enter the cell for photosynthesis (as well as the release of oxygen into the environment).
Explanation:
Answer: guard cells are a pair of cells that surround each of the stoma openings. to open the cells, they have to be triggered by one of many possible environmental or chemical signals. these can include more sunlight or higher than normal levels of carbon dioxide within the cell.
Explanation:
they open to regulate the gas and moisture exchange, hope that this is what you were looking for :)

If I study light and dark peppered moths in light and dark environments what would be the test variable and the outcome variable?
Answers
Answer:
the independent (test) variable is the physical changes (studying in the light or the dark) and the dependent (outcome) variable would be whatever you are trying to study (I assume it is the behavior of the moths)
Explanation:
the test variable is the variable you change during the experimental process and the outcome variable is what would be directly effected by the change in the experiment.
Test Variable--- changing the amount of light
Outcome Variable--- the effect it has on the moths

While Congress has the power to create new laws, they can be vetoed by the President. In addition, the Executive Branch must enforce these laws. What two
different constitutional principles are demonstrated by these relationships?
Select one:
A
checks and balances and separation of powers
B.
separation of powers and eminent domain
C
federal supremacy and due process
D.
separation of powers and quartering of troops
Answers
Answer:
A, Checks and balances and separation of powers.
Explanation:
Answer:
The correct answer is:
checks and balances and separation of powers
Explanation:
The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.

Retina. This is a thin layer of tissue on the back of the eye that receives the signals of light and transfers them to the brain so you can understand them as color and sight.Cornea. This is the front part, a reflective layer that "refracts" light. What this means is that light doesn't go directly through it, but its path is almost deflected a little.Sclera. This is the part that looks white from the front. It's a protein covering to your eye, and it's very close to the cornea.Iris. This is the actually colored part of your eye. If you have hazel or blue eyes, the iris is that portion of the eye. It allows differing amounts of light in.Pupil. This is the black part of the eye.

ENJOY groovie DAYNew genes created by genetic engineering produce brand new proteins called "novel" proteins. All proteins have the potential to trigger allergic reactions under certain conditions. Novel proteins are not recognized by the human immune system. In most cases, these proteins are tested in petri dishes rather than the plant itself.
What information did you include in your answer?
Novel proteins may be beneficial to human health.
Novel proteins may cause allergic reactions.
Additional reactions may occur once the protein is introduced to the plant, which could have negative effects on human health.
Answers
Answer:
Novel proteins may cause allergic reactions. Moreover, protein may also suffer folding when they are introduced into the plant, thereby converting them in potential allergens.
Explanation:
Genome engineering techniques are those procedures used in molecular biology to design genetically modified organisms by altering their genomes.
All proteins have the potential to cause allergic reactions. For example, celiac disease is an autoimmune disorder caused by an allergic reaction to the proteins of cereals; however, only a small fraction of proteins is associated with autoimmune diseases. There are many methods to study the potential of protein allergens, the enzyme-linked immunosorbent assay (ELISA) is currently the technique most widely used for this purpose by detecting antibody-antigen interactions (i.e., interactions between molecules of the immune system and antigen allergens).
Answer:
Novel proteins may be beneficial to human health.
Novel proteins may cause allergic reactions.
Additional reactions may occur once the protein is introduced to the plant, which could have negative effects on human health.

Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.
Answers
Answer:
B
Explanation:
the longest phase in the cell division is interphase because the DNA replication occurs in this phase
As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.
What is cell cycle?The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.
A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.
Thus, the correct option is D.

Answers
Answer:
6, 5, 4, 2, 1, 3
Explanation:
Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.
Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.
The process of transcription takes place in the following sequence:
1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.
2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.
3. The RNA nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.
4. DNA helicase unzips the DNA and RNA hybrid.
5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.
6. The two-strand of DNA is again joined via complementary base-pairing rule.
