The component of a vaccine that makes it effective is the antigen.

What is a Vaccine?

A vaccine is a biological preparation that induces active acquired immunity to a specific disease. It contains an agent that resembles an infective microorganism and is frequently composed of weakened or killed forms of the microbe, its toxins, or one of its surface proteins. Vaccines are intended to stimulate the body's own immune system in order to protect the individual from future infection or disease.

11) An antigen is a substance that causes the body to produce antibodies when it enters the body. These antibodies help the body recognize and fight the antigen if it enters the body again.

12) A vaccination is a way of introducing a weakened or killed version of a particular virus, bacteria, or toxin into the body. This weak or dead version of the virus, bacteria, or toxin stimulates the body's natural defense system to produce antibodies that are specific to that virus, bacteria, or toxin. These antibodies can then recognize and fight off the real virus, bacteria, or toxin if the body is ever exposed to it, thus preventing the individual from getting the disease. This is known as active immunity. The immunity created by the vaccination is typically long-lasting, and in many cases, lifelong.

Answers

Answer:

To survive in the stratosphere, you would need a space suit with a pressurized environment, oxygen tanks, a heat source, and a cooling system. You would also need a means of propulsion, such as a rocket or jetpack, to move around. In addition, you would need a way to communicate with other people on the ground or in other parts of the stratosphere. Finally, you would need a way to protect yourself from the extreme temperatures and radiation in the stratosphere.

Answers

Answer:

The correct answer is ''can change over time in response to environmental cues, allowing genes to be turned on or off as needed.''

Explanation:

Histones are a family of proteins involved in compacting DNA into structural units called nucleosomes. Histone modifications occur in response to environmental conditions, and modulate the structure of chromatin, that is, they alter the structure of nucleosomes and therefore chromatin, and thus activate the transcription process, in which the chromatin is in the euchromatin state (loose conformation, in which the DNA information can be read), or "off" state, in which the chromatin adopts the heterochromatin conformation (compact conformation, which prevents reading), respectively. These post-translational modifications are mainly acetylation, methylation, phosphorylation, although there are many others. These make up the “histone code” that can change the expression pattern of some genes by modifying the chromatin structure, activating or silencing these genes.

Answers

Around 1900, organizational and technological advancements in electricity sparked a new industrial revolution. The appearance of enterprises and cities was altered by electrical illumination and motors.

Businesses were able to expand their locations and increase their productivity thanks to centrally produced electricity. These accomplishments depended on the development of massive interconnected systems, most of which were monopolies controlled by corporations.

Before the war, the electricity business grew slowly, but in the 1920s it truly took off and played a significant role in the economic growth.

It offered factories a low-cost, effective source of power. It allowed for the simultaneous use of numerous sophisticated machines, paving the way for the development of mass production methods.

Because it provided the power required in consumers' homes for the new mass-produced goods, such as vacuum cleaners, refrigerators, and washing machines, electricity also contributed to the economic boom.

describe the process of blood clothing​

Answers

Answer:

Blood clotting normally occurs when there is damage to a blood vessel.

Explanation:

Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops.

Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

Please mark me as brainliest :)

Answer:

I think you mean blood clotting so umm

Explanation:

Blood is made up of many different cells—mostly red blood cells, white blood cells and platelets—as well as clotting factors. These and other elements float through blood vessels in a strawlike liquid called plasma.

The coagulation cascade is a complex chemical process that uses as many as 10 different proteins (called blood clotting factors or coagulation factors) that are found in plasma. Put simply, the clotting process changes blood from a liquid to a solid at the site of an injury. Here’s how the process works:

Injury. A cut on the skin or an internal injury creates a small tear in a blood vessel wall, which causes blood flow.

Vessel constriction. To control blood loss, the blood vessel immediately narrows (called constriction), which limits blood flow through the vessel.

Platelet plug. In response to the injury, tiny cells in the blood called platelets are activated. The platelets stick to one another and to the wound site to form a plug. The protein von Willebrand factor (VWF) helps the platelets stick to each other and to the blood vessel wall.

Fibrin clot. Next, blood clotting factors trigger production of fibrin, which is a strong, strandlike substance that surrounds the platelet plug and forms a fibrin clot, a meshlike net that keeps the plug firm and stable. Over the next several days to weeks, the clot strengthens and then dissolves as the wounded blood vessel wall heals.

B. Should the cleaner be taken off the market
C. Are there safer chemicals that could be used in the cleaner?
D.are there other possible causes of cancer?

Answers

D. are there other possible causes of cancer?

Scientific argumentation involves testing hypotheses through rigorous experimentation and examination of evidence. In this case, before drawing any conclusions about the relationship between the chemical in the household cleaner and cancer, other scientists would want to examine whether there are other possible causes of cancer that should be considered. The scientist who made the claim would need to show through experiments and studies that the chemical in question is the cause of cancer and not some other variable that was not controlled in the study. And therefore, evaluating the evidence and testing the hypothesis is the fundamental part of scientific argumentation.

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Do red blood cells have heterochromatin?

Answers

Yes, red blood cells have heterochromatin. Heterochromatin is a part of eukaryotic genomes responsible for gene expression DNA Repair and replication.

Differentiation of Erythroid to mature red blood cells(RBC) is done by multiple erythropoietin operated by signal transduction pathways, this process is also called terminal erythropoiesis. During this process chromatin gradually condenses which is critical for red cell terminal differentiation and final enucleation.

Therefore, the deciphered red blood cells could gain more space for hemoglobin development and flexibility to pass through terminal capillaries.

Chromatin exists in two forms euchromatin, is less condensed, and can be duplicated whereas heterochromatin, is highly concentrated and is typically not duplicated.

One way to determine the density of animals in an area is to use the mark-recapture technique. A number of individuals from a population are captured, marked so they are easily identifiable, and released back into the population. It's assumed that the captured and marked animals will randomly mingle with the rest of the population. Later, the population is re-sampled and the number of marked and unmarked animals is recorded. The following equation can then be used to estimate the size of the entire population. Gulded S Number of individuals marked in first catch Total population size, N Number of marked recaptures in second catch Total number of second catch If 25 Prairie Dogs were captured, marked, and released back into their population, and then subsequently 135 Prairie Dogs were captured, of which 18 were marked, what is the approximate total population size, N?

Answers

Answer:

The approximate total population size, N = 188 Prairie Dogs

Explanation:

The equation of the mark-recapture technique of determining population density is given below:

Number of individuals marked in the first catch/Total population size, N = Number of marked recaptures in second catch/Total number of second catch

If 25 Prairie Dogs were captured, marked, and released back into their population, and then subsequently 135 Prairie Dogs were captured, of which 18 were marked

Number of dogs marked in first catch = 25

Number of marked recaptures in the second catch = 18

Total number of second catch = 135

Substituting the given figures and solving for N, the total population:

25/N = 18/135

18N = 25 × 135

18N = 3375

N = 3375/18

N = 187.5

Thus, the approximate total population size, N = 188 Prairie Dogs
