How does using killed or weakened bacteria in an immunization help the body prevent infections?

A.) Antibodies are formed that fight those types of bacteria.
B.) The body develops a fever that kills beneficial bacteria.
C.) Bacterial reproductive cycles are disrupted.
D.) Bacteria-fighting viruses are activated.,

Answers

Answer 1

The answer is A.) Antibodies are formed that fight those types of bacteria.

To explain, your immune system protects you from invasive bacteria by attacking and destroying them. The problem is that your system needs to recognize invading organisms like bacteria. Remember that bacteria cells have many of the same types of structures as your own cells, and you do not want your immune system to attack your own body. Special cells called T-cells and B-cells participate in this process. To make a long story short, antibodies are special molecules that your immune system "labels" invading bacteria with, so that it knows what to attack. These antibodies only fit on molecular structures of the targeted bacteria.

When a dead or weakened bacteria, or even pieces of a bad bacteria are introduced to the body, the B-cells and T-cells create antibodies that label that specific type of bacteria, or even its parts. They also remember how to make them in the future, so that later, when and if infected with a live version of that bacteria, the immune system already makes the antibodies to fight that infection. The process can work for viruses too.

Why is the largest dna fragment band found closest to the well in which it was placed?

Answers

Because of the molecular weight of DNA, the larger fragment DNA is heavier and cannot move fast through the gel and found near to well whereas the small fragments with small molecule weight can move fast through the gel pores.

Final answer:

In agarose gel electrophoresis, larger DNA fragments migrate less due to the molecular sieve effect of the gel matrix which impedes their movement. Thus, they are found closer to the well they were loaded into, while smaller fragments move farther away.

Explanation:

The largest DNA fragment band is found closest to the well in because it travels slower through the gel during agarose gel electrophoresis. During this process, DNA fragments are loaded into a gel and an electric field is applied. Due to its negative charge, DNA moves towards the positive electrode. However, the gel matrix forms a molecular sieve, impeding the movement of larger molecules, allowing smaller fragments to pass through more readily. Hence, larger DNA fragments migrate less, staying closer to the well from which they were loaded, while smaller fragments travel farther.

Which cranial nerve is responsible for transmitting visual information?

Answers

the Optic nerve transmits visual info

Final answer:

The optic nerve is the cranial nerve responsible for transmitting visual information from the eye to the brain. It is one of the 12 cranial nerves in the human body which each have unique functions. Some cranial nerves transmit sensory information, others transmit motor information, and some a combination of both.

Explanation:

The cranial nerve responsible for transmitting visual information is the optic nerve. This nerve function includes transmitting visual signals from the eye over the axons of retinal ganglion cells, which form the optic nerve, to the brain. Specialized cells within this nerve carry various types of information such as form, movement, depth, brightness, color, and fine detail.

Humans have a total of 12 cranial nerves, each providing unique functions. For example, the olfactory nerve is responsible for transmitting information about smells from the nose to the brainstem, and the oculomotor nerve controls the opening and closing of the eyelid and some eye movements. However, when it comes to the transmission of visual information, the optic nerve is the primary player.

Generally, some cranial nerves transmit only sensory information, others mainly motor information, and some contain a mix of sensory and motor fibers, catering to the complex needs of our biological system.

A medical term that means puncture pleura to withdraw fluid is ____________.________________ ____________________

Answers

The answer is pleurocentesis.

The brainest answer would be appreciated.

Final answer:

The medical term for puncturing the pleura to withdraw fluid is thoracentesis, a procedure performed to alleviate symptoms and analyze the cause of a pleural effusion.

Explanation:

The medical term that means puncture of the pleura to withdraw fluid is thoracentesis. This procedure is used when there is an accumulation of excess fluid in the pleural space, a condition known as a pleural effusion, which can interfere with normal breathing. Conducting a thoracentesis involves inserting a needle into the pleural space, often using ultrasound guidance, to remove fluid for both therapeutic relief and diagnostic analysis.

The pleural space normally contains a small amount of fluid which serves as lubrication, allowing the lungs to move smoothly against the thoracic wall during breathing. However, when this balance is disrupted by inflammation, infection, trauma, or other medical conditions, it can lead to pleurisy or other complications such as spontaneous pneumothorax (collapsed lung), which requires prompt medical attention.

Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
a. liver
b. lungs
c. kidney
d. heart?

Answers

The correct answer is the lungs. Usually, in the systemic organs such as the liver, kidneys, and the heart; hypoxia or low oxygen levels cause the blood vessels supplying them to vasodilate to increase flow of blood and prevent ischemia. Adequate oxygenation of systemic organs cause the blood supply to vasoconstrict to prevent pooling of oxygenated blood and shunt it to other organs that need the oxygen more.

However, in the lungs, the opposite is true because in the setting of hypoxia, the blood vessels of the lungs vasoconstrict as to shunt the blood to other parts of the lungs with adequate oxygenation for the blood to be adequately oxygenated. If there is adequate oxygen in the lungs, then blood vessels vasodilate to efficiently get the oxygen from the lungs.

The answer for the question is the lungs.
Vasodilation means the smooth muscles in the blood vessel walls relax causing them to widen. The widening results in less vsacular resistance, thus the blood flow through the dilated vessel increases. Vasocontsriction on the other hand means the smooth muscles in the blood vessel walls contract causing them to narrow. The action results in blood flow through the vessels to be restricted.

Molecules of CO2 enter the ocean by diffusing into the sea surface waters and dissolving as part of the physical carbon pump. All BUT ONE variable influences how much CO2 will diffuse in any given location. That is A) wind. B) salinity. C) water temperature. D) geographic location.

Answers

Answer:B

Explanation:

bbbbBBBBBBBBBBBBBBBBBBbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

The variable that does NOT influence how much CO2 will diffuse in any given location is D) geographic location. The other three variables - wind, salinity, and water temperature - can all impact the amount of CO2 that diffuses into the sea surface waters.

For example, higher wind speeds can increase the rate of gas exchange between the atmosphere and ocean, leading to more CO2 entering the ocean. Salinity can affect the solubility of CO2 in water, and water temperature can impact the rate of biological activity that consumes or releases CO2.

The correct answer is geographic location, as this factor does not directly influence how much CO2 diffuses into the ocean. Wind, salinity, and water temperature can affect the solubility of CO2 in water and therefore impact the amount of CO2 that diffuses into the ocean in any given location.

A student is studying the ecology of a playa lake, which forms after a rainfall in a dry lake bed. the table lists the organisms that the student observed. which level of biological organization has the student described in the table?

Answers

The level of organization the student observed is community.

There are different levels of organization in Biology, more specifically Ecology, and these levels are listed below and explained in order from the highest to the lowest level.

The biosphere, which includes the largest part of the Earth, represents all living organisms on the land, in the ocean, and in the atmosphere.

An ecosystem is the next level of organization, which is a specific area with living organisms. It includes all the living organisms in that area but also the non-living environmental aspects, so it includes both biotic and abiotic factors.

A community includes all biotic factors of a specific area, so it is the biotic part of an ecosystem. This means that a community refers to all the populations of different species that live in a specific ecosystem and interact with each other.

A population is a level below a community, and above species, which refers to all of the individual organisms of one species that live in a specific community and interact with each other.

A species is a group of organisms that live in the same area, and interact with each other to breed, to produce viable offspring. All members of a species are genetically related and can be bred to produce fertile offspring.

Since the student in the example is observing a lake, which is an ecosystem, and he listed all the living organisms he found in that lake, we can conclude that the level of organization observed in the table is community. He described different shrimp species, and an insect species, and he didn't describe any abiotic factors, so that brings us to the level of community.
