Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms include a high fever, headaches, and body aches typically occur two to seven days after infection by the virus. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is-

Answers

Answer 1

Answer:

lytic, due to the quick onset of symptoms after infection

Explanation:

There are two different mechanisms by which viruses can replicate: the lysogenic cycle and the lytic cycle. The lytic cycle is a reproductive cycle where viruses hijacks the host cell's machinery in order to rapidly produce new viruses, which subsequently burst out of the host cell. On the other hand, the lysogenic cycle is a type of viral reproduction characterized by the integration of the viral nucleic acid into the host cell genome, staying hidden. In consequence, this cycle (lysogenic) is slower compared to the lytic cycle because it requires an additional step (i.e., genome integration).

Answer 2

lytic, because of the quick onset of symptoms after infection.

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.

Answers

Answer: volcanic

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.

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.

Answers

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.

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.

Answers

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 is cell differentiation?

Cells are the fundamental cornerstones of all life. Numerous numbers of cells construct the human body.

The process by which dividing cells alter their functional or phenotypical type is known as cell differentiation. All cells, it is assumed, derive from stem cells and acquire their functions as they mature.

In response to antigen exposure, some differentiation occurs. Differentiation alters a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals significantly.

These changes are primarily the result of highly controlled changes in gene expression and are the subject of epigenetic research.

Mesenchymal stem cells, epithelial stem cells, and muscle satellite cells are the three types of differentiated cells.

Thus, the answer is differentiation.

BrotherEye

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.)
