Why must DNA replication happen in order for the stem cell treatment to work?
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Explanation:
The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities? A. The wing and front limb are homologous structures; each evolved from a common ancestor. B. The wing and front limb are analogous structures; each evolved from a common ancestor. C. The wing and front limb are analogous structures; each evolved independently. D. The wing and front limb are vestigial structures; one evolved from the other.
Answer:
A
Explanation:
The correct answer would be that the wing and front limb are homologous structures; each evolved from a common ancestor.
Homologous structures are organs of different organisms that look similar in structure but perform different functions on their respective owners. They are as opposed to analogous organs which look different on different organisms but perform similar functions on them.
An example of the homologous organ is the wing of birds and the fore-limbs of mammals which are both built on a five-digit plant, also known as pentadactyl plan. While birds use their wings to fly, the fore-limbs of mammals are adapted for grasping or walking. An example of the analogous organ is the wing of birds and the wing of insects. They both look structurally different but are both for flying.
The correct option is A.

What best describes a high pressure system? Question 4 options: Warm, rising air that creates cloudy, rainy weather Warm, rising air that creates clear, sunny weather. Cool, sinking air that creates cloudy, rainy weather Cool, sinking air that creates clear, sunny weather
Answer:
a high pressure system : Cool, sinking air, that creates clear, sunny weather.
Explanation:
The characteristics of the high-pressure system is marked by the presence of the cold and sunny days as compared to those of the warm and low-pressure pressure regions of the world. The air is light and lifts up easily and hence leading to the formation of clouds and rainfall. As compared to the cold air mass that is dense and hence has low moisture contents.What similarities in the development lead scientists to infer that opossums ,chickens, salamanders,and fish share a common ancestor?

The statement that can be used to describe DNA methylation is "A mechanism involving attachment of methyl groups to certain bases for the long-term inactivation of genes during development."
Option D.) is correct.
Define DNA methylation.DNA methylation controls gene expression by attracting proteins implicated in gene repression or preventing transcription factor(s) from binding to DNA. The pattern of DNA methylation in the genome varies during development as a result of a dynamic process that includes both de novo DNA methylation and demethylation.
DNA methylation is an epigenetic mechanism that happens when a methyl group is added to DNA, altering the function of genes and influencing gene expression.
It's a process that involves attaching methyl groups to specific bases in order to inactivate genes for a lengthy time throughout development.
So, the statement that can be used to describe DNA methylation is option D.)

What is Messenger RNA?
Single-stranded RNAs of the type known as messenger RNA, or mRNA, are used to make proteins. mRNA is created during transcription from a DNA template.
The function of mRNA is to transport protein information from DNA in the cell's nucleus to the cytoplasm (watery center), where the machinery responsible for producing proteins reads the mRNA sequence and converts each three-base codon into an amino acid that will eventually create a protein.
mRNA, or messenger RNA. Therefore, mRNA is actually a type of nucleic acid that aids in the cellular machinery's ability to read the human genome, which is encoded in DNA.
Therefore, UAGOUU is a messenger RNA strand that encodes this information.

Answer:It B
Explanation:
Metals and minerals accumulate in specific regions on Earth due to _______ activity and as part of the rock cycle. When sustainable yield is achieved, the rate of replenishment is equal to the rate at which the resource is harvested. This means that the resource can be harvested _______. Plate motion can create the proper temperature and _______ underground for hydrocarbons to release from kerogen.
Answer: volcanic
indefinitely
pressure
Explanation:
It should be noted that metals and minerals are regarded as non renewable resources which implies that they cannot be replenished.
They accumulate as a result of volcanic activities which takes place in the Earth. The resources can be harvested indefinitely when there is achievement of the sustainable yield. Plate motion can then create the proper temperature and pressure underground that is required for the hydrocarbons to release from kerogen.
Answer:
1. Non-renewable
2. Volcanic
3. Indefinitely
4. Pressure
5. Metals are found in rocks and can be moved by erosion and rainfall. these processes carry metal away from weathered rock, causing metals to accumulate in sediments, rivers, and streams.
