When the material collides with the Earth's magnetic field and trapped radiation belts, it can dump particles into our upper atmosphere to cause the Aurora.

When this distorted magnetic field eventually snaps back, it accelerates electrified particles towards the Earth.

\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}

Active Immunity, Immunity which is acquired by the own immune response of the body.

Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.

                             x---------------------------------------------------x

\Large\textbf{Vaccination:}

Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.

a vaccine works by training the immune system to recognize and fight pathogens, either viruses or bacteria. so certain molecules from the pathogen must be introduced into the body to trigger an immune response. so basically your not really immune your body will just know how to deal with it

Why is a food web a better representation of relationships within an ecosystem than a food chain? A. A food web shows that most organisms consume and are consumed by more than one organism. B. A food chain shows that most organisms consume and are consumed by more than one organism. C. A food chain shows only a single pathway of energy. D. A food web shows a single pathway of energy flow through the ecosystem.

Answers

A.

a food chain is almost never possible, as in any ecosystem most species are consumed by more than one species of a higher trophic level.
c. a food chain shows only a single pathway of energy 

The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the _______ and the _______ of the conductor. A. length, speed
B. color, capacitance
C. resistance, current
D. distance, circumference

Answers

Answer:

Length and speed.

Explanation:

According to Faraday's law, the voltage induced in the conductor is equal to the product of magnetic field, length and speed of the conductor.

The formula to find the induced voltage in the conductor is:

ξ = Blv

Here, ξ= emf induced, B is magnetic field, l is the conductor length and v is the conductor speed.

From the above formula, it is clear that voltage of a conductor depends upon the length and speed of the conductor.

Thus, the correct answer is option (A)
The correct answer is A). Length, Speed.

Taking into consideration the function of the types of tissue and their integrated role in the how the body works, which types of tissue play a role in protecting the body from internal and external hazards?I. epithelial
II. muscle
III. connective
IV. nervous
I and III
III and IV
I, II, and IV
I, II, III, and IV

Answers

Answer:

The correct answer is option D, I, II, III, and IV

Explanation:

The function of four tissues in protecting the body from internal and external hazards

a) Epithelial tissue – It is a sheet of cell cover exterior surfaces of the body and also is present in the internal lining of cavities and passageways

b) Connective tissue – It connects cells and organs of the body together to make sure that they all  helps in the protection, support, and integration of different  parts of the body.  

c) Muscle tissue – Helps in  stimulating  and contracting to provide movement

d) Nervous tissue – Causes  propagation of electrochemical signals in the form of nerve impulses to communicate with all the regions of the body  

I just took the review the correct answer is D, I, II, III, and IV
