<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}$

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

<h2> </h2><h2> $\Huge\text{Vaccination:}$ </h2>

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.

1. After mitosis in animals, cytokinesis takes place. What happens during cytokinesis?

il63 [147K]

The correct answers are as follows:
1. During cytokinesis, THE CELL MEMBRANE PINCHES IN TO FORM TWO NEW CELLS.
Cytokinesis is the physical process of cell division, it divides the cytoplasmic content of the parental cell into two new daughter cells. Cytokinesis takes place in both mitosis and meosis.
2. The correct order of the phases of mitosis are as follows: PROPHASE, METAPHASE, ANAPHASE AND TELOPHASE.
Mitosis is the process of cell division by which a cell is divided into two new cells. The process occurs in four basic stages and result in the formation of two new cells.
3. The following terms are related to sexual reproduction: MATING SYSTEM, GAMETE FORMATION AND AMPLEXUS.
Amplexus refers to the mating positions of frogs and toads during sexual reproduction. Mating system refers to the number of mating partners that an animal has during the mating period. Gamete formation is the process by which sex cells are made and it occurs in both male and female animals.
4. As a cell is preparing to divide by mitosis, the DNA MUST BE COPIED.
When a cell is getting ready to divide by mitosis, it will undergo a stage called interphase, during which the cell prepare for cell division. During interphase, the cell undergo some process and these include the copying of the DNA. The cell copies its DNA so that it has two copies of each strand.

Mutations such as polyploidy and crossing over provide the genetic basis for

EleoNora [17]

Answer;

Evolution

Mutations such as polyploidy and crossing over provide the genetic basis for evolution.

Explanation;

Evolution is the change in the characteristics or traits of a species over several generations and relies on the process of natural selection.

It occurs when some individuals or some alleles (alternative form of gene) reproduce themselves more than others,increasing their prevalence in subsequent generation.

Polypoidy and crossover brings about mutations that cause changes in characteristics and traits over time resulting to evolution.

Receptors for acetylcholine are located on the

elena-s [515]

Answer:

plasma membrane of the target cell

Explanation:

There are two main types of acetylcholine (ACh)receptors:

muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
nicotinic ACh receptors (nicotin is agonist) which are ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).

5. What are the advantages of sexual reproduction?

nalin [4]

Answer:

There are advantages and disadvantages of sexual reproduction, compared to asexual reproduction. The main issues are: Advantages: More variation assists with survival. It increases the chance that at least some offspring of a parent survive.
