How does water cause frost wedging?
A
Water attracts lightning, which breaks apart huge boulders into many smaller pieces.
B
Water carries sediment to large rocks, causing them to rub against each other.
C
Water freezes and thaws inside rock cracks, causing them to widen and then split.
D
Water slowly wears down a rock’s sharp edges, leaving behind a smooth surface.
Answer:
C. Water freezes and thaws inside rock cracks, causing them to widen and then split.
Explanation:
When water gets in the crack at the bottom and freezes, frost wedging occurs.
Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger (see diagram below) and may fracture, or break, the rock.
1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?
Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.
What is Mitosis?
Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.
In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.

O 38%
O 50%
O 63%

answer is 50
Explanation:
i gess on quiz and it was correct
PS: Love you babe ill see you when you get home.
A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
What is Forest soil?Forest soil has more moisture than sandy soil therefore the types of plants that are grown in soil of forests are more qualitative and more superior than the sandy plants which are facing certain limitations and facing certain situations.
Forest soil supports plant life, but sandy soil does not support any plants. Forest soil produces more superior life and the plants life are found in the forest area and the sandy plants are lesser found in the sandy areas.
The reason for vegetation in forests is because of the supportive factors that are involved in the good plants life. The soil type that is the richest in organic material would be a dark-colored soil. Decaying matter turns brownish-black which makes this type of soil having a dark color even almost black.
Therefore, A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.

Answer:
The answer is F.
Explanation:
The reason why is the Mitochondria converts glucose to energy. If it were to be removed, protein production would stop, normal functions would cease, homeostasis would be off balance. also because activities going towards the Nucleus. No control center, no protein production since ribosomes are made there. Thus, destroying that cell completely.

What is the charge of the outside of the DNA molecule?
Answer:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?
A. 20%
B. 70%
C. 40%
D. 60%
Answer:
A. 20%
Explanation:
A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.
Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.
A + T + G + C = 100%
Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S
Since A=T = 20% in accordance to Chargaff rule.

1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.
Answer:
2. Sarah
Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.
A student finds a beaker containing a substance in the laboratory. The student filters the contents of the beaker and notices that a solid is left on the filter paper.
What can the student conclude about the type of matter of the original material?
Answer:
These are my answer choices so I guess it's an mixture, it's a mixture of filtration .. so its a mixture
Explanation:
(1) The original material was a mixture.
(2)The original material was a compound.
(3)The original material was either an element or a compound.
(4)The original material was either a mixture or a compound.
A beaker containing a substance is in the laboratory. Upon filtering, a solid is left on the filter paper. We can conclude that the original material was a mixture.
Filtering is a method for the separation of heterogeneous mixtures. A filter paper is placed in a funnel and the mixture is poured over it. The liquid passes the filter while the solid is retained. Since this was the situation of the student, we can conclude that the original material was a mixture. After the filtering, the student will have 2 homogeneous systems.
