It doesn’t is actually makes u sick sometimes but if u agree then vaccinations mean when only a bit of the pathogen is ingested into to u for ur body to become immune and so if u get the disease yours body has already made antibodies which contain a special format in which they break down the pathogen faster.and the pathogen will be broken down quickly as the process is faster when your body already contains the code against it.

The plant cell's central vacuole Group of answer choices occupies a large area of the cell All choices are correct is a reservoir for water. Stores nutrients and cellular waste products.
Answer:
Stores nutrients and cellular waste products.
Explanation:
Vacuole is a space that is line with membrane and within the cell that lacks cytoplasm but filled with fluid.
They are important cytoplasmic organelles and perform certain functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
In plant, large central vacuoles enable them to attain a large size without accumulating the bulk that would make metabolism difficult.
A student combined baking soda and vinegar. Is this an example of a chemical reaction? Use evidence and scientific reasoning to support your claim.
Answer:
It is not a chemical reaction, because you can still separate it, meaning it is a physical change. Also it did not make a new substance, burn, or rot also making a physical change.

If a person is breathing normally, which of the following could prevent him from using his body to exercise normally?
not eating enough food, because cells need molecules from both food and air to work
nothing, because he would be able to exercise normally as long as his cells are getting molecules from the air
not getting enough sleep, because the body only makes energy for exercise while asleep
not getting enough sunlight, because cells need sunlight to function
Answer:
Not eating enough food, because cells need molecules from both food and air to work.
Write a paragraph explaining how energy flows through an ecosystem.
Be sure to use the following terms:
Energy Pyramid Sun
Trophic Level Producer,
Primary Consumer Decomposer
Secondary Consumer Tertiary Consumer.
Answer:
The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
How energy flows through an ecosystem is summarized below.
Energy flows through an ecosystem in the following order:
Sun ----> Producer ---> Primary consumer ---> Secondary consumer ---> Tertiary consumer ---> Decomposer.
Some of the energy from the sun is fixed by the producer through a process known as photosynthesis. The producers are usually green plants and photosynthetic bacteria.Primary consumers feed directly on the producers.Secondary consumers feed on the primary consumers.Tertiary consumers feed on the secondary consumers.The decomposers feed on the remains of the tertiary consumers.As the energy flows from producer to the different consumers, and to the decomposer, only about 10% of the energy available in each trophic level move to the next with the rest being lost to heat.
Hence, an energy pyramid is created as we move from the lower trophic level to higher trophic levels.

5. Balanced forces cause a change in the motion of plate tectonics. True O False
Answer:
False, they do not cause a change
Explanation:
Balanced forces will cause no change in the speed of an object. Balanced forces acting on an object in opposite directions and equal in strength, as shown in the arrows below, do not cause a change in the speed of a moving object. Objects that are not moving will not start moving if acted on by balanced forces.

During DNA replication what occurs
Answer:
What happens during DNA replication?
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

Photosynthesis uses all of the following except
to make food.
carbon dioxide
O light energy
O chemical energy
water
is it’s A?
Answer:
No I think its C
Explanation:
Photosynthesis is a process that takes place due to water, sunlight, carbon dioxide and creates oxygen.
All the green plants carry out the process of photosynthesis in the presence of sunlight, the carbon dioxide, and water.
Thereby releasing oxygen and energy. The first organism that evolved to make photosynthesis was the blue-green algae and later on, cyanobacteria evolved which lead to the origin of oxygen on the earth.Thus the photosynthesis is a process that results when all three are processes by the plants.Giving out the chemical energy in the form of sugar and air to breathe. Hence the correct option is C.

What causes the light to refract as it
passes from air to water?
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction
