Answer: B
Explanation: The rest are produced through mitosis.
A type of cell that is created during the process of meiosis is known as a sperm cell. Thus, the correct option is C.
What is Meiosis?Meiosis can be defined as the type of the cell division which goes through or in which two daughter cells has been produced from the parental cell that has not genetically identical to their real parental cell. Meiosis has been also known as the reductional division.
The germ cells must be generally produced by the process of the meiosis. It is because these cells has been usually contain half of the amount of the genetic material as it is compared to the parental cell. After producing these gametes, the cells has undergo through the process of the fertilization in order to produce the product known as zygotes which contain the genetic material of both males and females.
Therefore, sperm cells and egg cells are the types of cells that are created during the process of meiosis.

Lexie lives at sea level, but her family rented a vacation cabin high in the Rocky Mountains for two weeks. She noticed a difference in her breathing.
An image of a mountain with three circles going up the side of it. The lowest circle is filled with many, smaller circles. The middle circle has fewer circles that are farther apart. The highest circle has the fewest circles that are the farthest apart.
What do the molecules in the circles model regarding altitude?
A. Air pressure increases at higher altitudes.
B. Air density decreases at higher altitudes.
C. There is a greater gravitational pull on air molecules at higher altitudes.
D. Temperature has a decreasing effect on air molecules at higher altitudes.
Answer:
B. Air density decreases at higher altitudes
Explanation:
Since air is compressible, air from higher altitudes will compress air from lower altitudes. As a result, air density at lower altitudes will be greater than air density at higher altitudes. Air particles at the highest altitudes, not being acted upon by air above it, will be more spread out.
Explain why organisms are more likely to be well preserved in mud than in sand? Justify your response in
two or more complete sentences in the essay box below.
PLS I NEED HELP ASAP!!!
Answer:
Explanation:
Organisms are well preserved in mud because mud has high water holding capacity. It retains water and does not allow oxygen flow which can destroy the remains of organisms. There are some microbes that preserved whose growth are enhanced in water related environment like mud.
But sand cannot retain or hold water. It drains it off and all oxygen bearing water to flow which enhance decay compared to mud. It can't preserve organisms because of the above reasons.
Answer:
Organisms are more likely to be well preserved in mud than in sand because sand allows oxygen that has water(oxygen-bearing water) to flow through it. This type of oxygen speeds up decay. Mud does not have this oxygen so it prevents the flow of water, and keeping oxygen away means it slows decay of the buried organisms.

2. Many people believe that
a mutation will always result
in the formation of a deadly
tumor, or the development
of a major body defect.
Explain why this is incorrect.
Answer:
A mutation is simply an error in the copying of DNA it generally does not have major effects. Mutations are changes in the DNA sequence.
Tumors form by an uncontrolled error in a stage of mitosis that continue to generate cells that aren't correct and eventually lead to tumors.
Explanation:
This is incorrect because not all mutations results in tumor or
development of a major body defect.
What is Mutation?Mutation refers to the changes or alterations which occur in the
nucleotide sequence of a DNA.
AA major body defect only occurs if the change in DNA affects a particular
structure or function of the part involved. Tumor on the other hand is
formed when uncontrolled errors in mitosis during growth and
replacement of tissues.

3. Explain the digestion of a bite of mixed feed in a cow and a pig. Do this in a stepwise progression beginning with prehension and ending in defecation.
Answer and Explanation:
The process which our body uses to absorb and breakdown nutrients stored in food are called digestion. The cow has a unique digestive process to break down the food. It has four stomachs. When a cow takes a bite of food, it chews the food very little and then swallow. The reticulum and the rumen are the first two cats' stomach; the unchewed food travels to these stomachs—the food stored in this two stomach until later. Cow rests when this process of eating is completed. Later, cow coughs up unchewed food bits named cuds and chewed it thoroughly before swallowing again. The omasum and abomasum are the third and fourth stomach of a cow. The cuds then go to them, where it is completely processed. Some digested food enter in the bloodstreams, while rest goes towards the nourishment of cow. In the pig, the digestion of food starts in the mouth. Food is masticated into small pieces and mixed with saliva, then swallowed. After swallowing the food, it moves down into the stomach. In the stomach, food mixed with enzymes which help in the breakdown of the food. The food enters in the small intestine, where most of the digested food is absorbed. Then the food enters the large intestine. Large intestine absorbs salts and water from undigested material and get rid of left-over.

Acid rain contains chemicals that can break rocks. Which describes this interaction?
A) hydrosphere and geosphere
B) geosphere and biosphere
C) biosphere and atmosphere
D) atmosphere and hydrosphere
E) hydrosphere and biosphere
The correct answer is A) Hydrosphere and geosphere
Explanation:
Planet Earth comprises different systems or spheres. Moreover, these systems often overlap or interact. This occurs in the case of acid rain that breaks rocks. Acid rain as well as other forms of water such as snow, hail, liquid water in rivers, etc. belongs to the hydrosphere, which includes all water (H2O) on Earth. On the other hand, the rocks belong to the geosphere, which comprises all the surface and materials in it such as rocks or minerals. This implies in this context the rocks from the geosphere interact with the rain of the hydrosphere.

Which of the following statements correctly describes the difference between the semiconservative model of DNA replication and the conservative model of DNA replication?
A.The semiconservative model states both strands of DNA remain together after replication and the conservative model states both strands separate.
B. The semiconservative model states single-stranded DNA strands are used as a template strand to create newly synthesized DNA strands and the conservative model states only one side is used as a template.
C.The semiconservative model states the DNA strands are randomly paired with a newly synthesized DNA strand and the conservative model states only new strands are paired.
D.The semiconservative model states the two original DNA strands separate and are used as template strands to create newly synthesized DNA strands and the conservative model states the two original strands remain together.
Answer: B.
Explanation: As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
The statement that correctly describes the difference between the semi-conservative model of DNA replication and the conservative model of DNA replication is as follows:
The semi-conservative model states single-stranded DNA strands are used as template strands to create newly synthesized DNA strands and the conservative model states only one side is used as a template.Thus, the correct option is B.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact. While in the conservative model of DNA replication, the entire original form of the DNA double helix function as a template and synthesize a new double helix.
Therefore, the correct option for this question is B.
