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
[tex]\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}[/tex]
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
[tex]\Large\textbf{Vaccination:}[/tex]
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.

What are the functions of carbohydrates, peripheral proteins, and cholesterol in the cell membrane?
Answer:
Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells.

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

marine phytoplankton are not found at great depths in the ocean because of the lack of
Answer:
sunlight
Explanation:
Marine phytoplanktons are not found at great depths in the ocean because of the lack of sunlight at these depths.
Phytoplanktons need sunlight to survive. They utilize light for food production through photosynthesis. Without light, this process would become limited and the phytoplanktons will die of starvation.
At great ocean depths, sunlight penetration becomes limited and thus, phytoplanktons also stay away from these depths.
if glucose is in higher concentration outside the cell than inside, but the plasma membrane and other surface layers of the cell do not allow glucose to pass through, which is the most likely type of transport for glucose? and Why?
a simple diffusion
b Osmosis
c Facilitated diffusion via a gated channel
d Facilitated diffusion via an aquaporin
e Facilitated diffusion via an ion channel
Answer:
a
Explanation:
ok ok as you were saying you said it is hard for the glucose concentration in the body this also had to go out so but the plasma membranes and other surfaces layers cell layers of the layer of the soil do not allow to close glucose to pass through which is most likely type of transport type of transport for kids and you still said why it is because it gives energy to the body

how sunlight regulates the productivity of algae and the number of catfish in a pool.
Answer:
Algae produces food and catfish also needs warm water.
Explanation:
Sunlight regulates the productivity of algae and the number of catfish in a pool because algae produces food in the presence of sunlight during the process of photosynthesis. If algae produces more food, so more food is available for the catfish and as a result the population of catfish increases. If no sunlight occur on the pool the algae is unable to produce food and the population of catfish decreases. Sunlight increases the temperature of water which makes environment suitable for the catfish because catfish needs slightly warm water for its growth. So we can say that sunlight has a great affect on algae and catfish.

Answer:
Darwinian fitness differs from the “physical fitness”, which is more associated with health, muscle tissues, oxygen, and physical effort. Darwinian fitness is more concerned about reproductive success. Darwinian fitness describes how successful an organism has been at passing on its genes.

Which two parts of the water cycle involve water in its gas form?
A) Condensation and collection
B) Evaporation and condensation
C) Precipitation and condensation
D) Runoff and evaporation
Explain why.
Evaporation and condensation involve water in its gas form. Hence, option B is correct.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle. It is a very important cycle for the survival of living organisms.
The water cycle is composed mostly of four processes: evaporation, convection, precipitation, and collection. When the water in rivers, lakes, or the ocean is heated by the sun and turned into vapor or steam, this process is known as evaporation. In condensation, water vapors are converted into water.
The parts of the water cycle that involve water in its gas form are evaporation and condensation. Hence, option B is correct.

True/ False: Substances will diffuse more rapidly through a dense substance. Explain
Answer:
I'd say true
Explanation:
Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.
Answer:
False
Explanation:
As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.
The statement, "the total mass of the product must equal the total mass of the reactants" is known as the ____
Answer:
The statement, "the total mass of the product must equal the total mass of the reactants" is known as the Law of conservation of mass.
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Consider the example of photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
There are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
27. City planners want to build a new airport. The city is located near a river that
often changes course. How could satellite views assist the planners in choosing
a location for the airport? (8.9C)
a. Views could be used to locate the areas of least vegetation
b. Views could be used to predict the future course of the river
c. Views could be used to locate flat and level areas
d. Views could be used to make topographic maps of the area
I
Answer:
d. Views could be used to make topographic maps of the area.
Explanation:
Satellite views helps the planners in choosing a location for the airport because it provides topographic maps of the area which contains all information about natural features of that area such as roads, railways, power transmission lines, contours, elevations, rivers and lakes. So the satellite images provides a great help to the planners to find out suitable place for the airport.

Answer:
apoptosis
Explanation:
Explanation: Apoptosis is programmed cell death, and it usually occurs when the DNA of the cell is damaged beyond repair. Photosynthesis and glycolysis are normal metabolic processes of the cell, and would not result from irreversible damage.
