The options are missing from the question,the missing options are;

a. Anaphylactic

b. Histamine

c. Immediate allergic

d. Delayed allergic

e. B-cell mediated.

The correct answer to the question is option D

DELAYED ALLERGIC.

Delayed allergic response is a type of late response to antigen that occurs 48-72hours after exposure to an antigen.

This type of allergic response is mediated by T-cells and macrophages.

They are otherwise known as delayed hypersensitivity response/reaction.

The response is delayed because there is sensitization upon first exposure to the antigen, therefore if there is a re-exposure,a secondary cellular response is initiated triggering the actions of the already sensitized T-cells and macrophages.

Arrange the sentences in order to describe how oxygen from air is transported to the cells in the kidneys.

Answers

Answer:

The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.

If an element has 6 protons, 6 electrons, and 8 neurons, then what’s the atomic number

Answers

Answer:

The atomic mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.

Explanation:

The six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.

The atomic number is the number of protons that is in the atom. If an element is having 6 protons, 6 electrons, and 8 neurons, then its atomic number will be 6, i.e. Carbon.

What is atomic number?

Atomic number is the number of a chemical element as represented in a periodic system.

These elements are arranged in order of increasing number of protons in the nucleus.

The number of protons is always same as that of electrons in the neutral atom, which is also the atomic number.

Thus, here the number of protons given is 6 so the atomic number will be 6.

A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.

Many people mistakenly believe fungi are plants. However, fungi are neither plants nor animals but rather organisms that form their own kingdom of life. The way they feed themselves is different from other organisms: they do not photosynthesize like plants and neither do they ingest their food like animals.

The true statement when describing sex-linked inheritance is ; ( B ) The alleles are found on the X and Y chromosome

The alleles responsible for reproductive inheritance from parents to offspring is contained in the X and Y chromosome of the reproductive gametes.

The female gametes contains double X chromosomes while the male reproductive gametes contains one X and one Y chromosomes. The alleles that are responsible for inheritance ( i.e. the sex of the offspring ) are contained in this chromosomes.

Which axiom is used to prove that the product of two rational numbers is rational?(1 point) Integers are closed under multiplication. Integers are closed under division. Whole numbers are closed under division. Natural numbers are closed under multiplication.

Answers

Answer: Integers are closed under multiplication.

Explanation:

Rational numbers are numbers of the form:

a/b

such that a and b are integers.

The axiom: " Integers are closed under multiplication. "

Says that if we have two integers, x and y, then:

x*y is also an integer.

So if we have two rational numbers,

a/b and c/d

Such that a, b, c and d are integers, and we multiply them, we have:

(a/b)*(c/d) = (a*c/b*d)

the numerator is a*c is the product of two integers, so this is an integer by the previous axiom.

the denominator is b*d, also a product of integers, so this is an integer.

then (a*d)/(b*d) is the quotient of two integers, then this is a rational number.

Answer:

the second one... Integers are closed under multiplication

You notice that your aunt, who has generalized anxiety disorder, is often restless and has trouble concentrating. Which area of her brain is most likely responsible for her responses to anxiety-provoking events? A. Amygdala B. Hypothalamus C. Anterior cingulate cortex D. Cingulate gyrus

Answers

Answer:

Amygdala

Explanation:

Generalized anxiety disorder (GAD occurs when an individual experiences excessive and continuous worry and anxiety about certain things ,It is caused by  over activation  of the region of the brain that mediate response to fight and flight stimulus and fear,the amygdala.

Its  symptoms are  difficulty with concentrations, overthinking ,indecision, irregular sleep patterns.

Two brain circuits  transmitted  sensory stimuli of fear or danger in the brain  to two regions of the brain,

1. the peripheral cerebral cortex for voluntary decisions

2. the Amygdala for involuntary emotional decision.

The amygdala  is concerned with  how the body reacts to the effects of the stimuli in the immediate environments, the interactions of the stimuli with  the emotions of the subject, and the involuntary response .

To  respond to the  stimuli of fear. The amygdala stimulates the hypothalamus.The latter activate the cardiovascular and breathing centre .Hence,adrenaline is released into the blood stream.The  increases involuntary response to anxiety,which gives a fast response..The cerebral cortex response takes time to relay response.

Amygdala,  stores memories of all emotions, fear, and anxiety. In patients with  this disorder, the Amygdala is sensitive and had been adapted to the memory   of fear and anxiety stored.Therefore, every slight normal event which should give any danger  is over reacted to  by the amygdala with  fear or flight response, This triggers the two brain circuits  to give anxiety-provoking events.

Shivering and vasoconstriction would be signaled to cause a: A. increase in pH. B. decrease in temperature. C. decrease in pH. D. increase in temperature.

Answers

Answer:D

Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body

Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.

What is thermoregulation?

Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.

During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.

Therefore, vasoconstriction and shivering signal the body to increase the temperature.

Chylomicrons are synthesized in intestinal epithelial cells  to transport long-chain triglycerides to the tissues. Therefore, option (A) is correct.

What are chylomicrons?

Chylomicrons are lipoprotein particles made up of triglycerides, phospholipids, cholesterol, and proteins. They are also known as extremely low-density lipoproteins. They move dietary lipids from the intestines to other bodily parts.

Chylomicrons deliver lipids ingested from the gut to the adipose, cardiac, and skeletal muscle tissues, where their triglyceride components are digested by the action of the lipoprotein lipase, releasing the free fatty acids that may then be absorbed by the tissues.
