Why do you think the flu vaccine is recommended every year?
How does the vaccine affect the immune system?
When is the best time to get a flu vaccine? Why?
Is the vaccine effective?
Who is and who is not recommended to receive a flu vaccine? Why do these recommendations exist?
Why is it important for the CDC to update its flu vaccination recommendations each year?
I'll answer what i can
Answer:
Its recommended because it can help fight the flu if you get it
It affects the immune system by training it to target the flu, and gain resistance to it
The best time is during cold, due to the fact that cold helps the virus (heat kills some viruses)
depending on the person depends on whether its effective or not.
Recommended for taking it, i do not know. Sorry for the missing answer.Its important for the CDC to update it every year because the flu isn't always the same, and can adapt to the shot to where it has no effect.
Answer:
full answer for plato/gradpoint :) its 100% correct it was my answer
Explanation:
Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses. When you get vaccinated, your immune system produces antibodies to protect you from the viruses included in the vaccine. But antibody levels may decline over time — another reason to get a flu shot every year.
Getting a flu vaccine prepares your immune system for the flu. A flu vaccine teaches your immune system to recognize that virus as a threat. While some people may still get the flu after having a flu shot, they'll probably have a milder form of the illness. That's because antibodies made in response to the vaccine can still provide some protection.
The flu virus is around all year, but it spreads more easily from September through the spring, generally peaking between December and February. It takes about 2 weeks to develop enough antibodies from the flu vaccine to protect you against the flu. Protection fades over time, so getting vaccinated before September may leave you more vulnerable toward the end of flu season. You can continue to get the vaccine through late winter to early spring.
How well the flu vaccine works (or its ability to prevent flu illness) can vary from season to season. The vaccine’s effectiveness also can vary depending on who is being vaccinated.
People who can get the flu shot: Different flu shots are approved for people of different ages. Everyone should get a vaccine that is appropriate for their age. There are inactivated influenza vaccines (IIV) that are approved for people as young as 6 months of age. Pregnant women and people with certain chronic health conditions can get a flu shot.
People who should not get the flu shot: Children younger than 6 months of age are too young to get a flu shot. People with severe, life-threatening allergies to flu vaccine or any ingredient in the vaccine. This might include gelatin, antibiotics, or other ingredients.
These recommendations exist for the safety of people having different health conditions.
Every year the flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu.
Why consumer in a food chain can’t get access to all energy in food chain?
Please I really need the answer
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up

14. The Endosymbiotic Theory explains
*
O A. The origin of eukaryotes
O B. How species develop
O C. How bacteria live
O D. Why cells rely on one another
Answer:
A) the origin of eukaryotes
Explanation:
The Endosymbiotic theory talks about how the ancestors of modern eukaryotic cells were once 2+ prokaryotic cells. This theory says that one prokaryotic cell basically lived inside another prokaryotic cell and these cells formed a long term relationship. The prokaryotic cell eventually became a permanent part of the host and eventually evolved into modern day eukaryotic cells.
The Endosymbiotic Theory explains the origin of eukaryotes.
What is endosymbiotic theory?The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes.
The most significant examples of endosymbiosis are represented by the endosymbiotic acquisition of plastids and mitochondria, introducing photosynthesis and respiration to eukaryotes.
Eukaryotic cells may have evolved when multiple cells joined together into one. They began to live in what we call symbiotic relationships. The theory that explains how this could have happened is called endosymbiotic theory.

Interdependence of animals in the rainforest. Help me plss
Answer:
The Halloween Crab
Explanation:
Interdependence is the idea that all species depend on one another in some way. This connection is very important to the health of the rainforest because every species in the rainforest relies on at least one other to survive.
The Halloween Crab can only be found in the rainforests of Central America. The crab lives in borrows it makes in the ground. By carrying leaves into their burrows, the crabs help the soil get the nutrients it needs. Them eating seeds off the ground ensures new plants will be able to grow. Finally, once they die their borrows will be used by other arthropods such as insects, spiders and other crabs.

Which statement regarding the structure or function of ribosomes is correct?
a. In eukaryotes, the ribosomes found in chloroplasts and mitochondria are 70S ribosomes, which are similar in size to prokaryotic ribosomes.
b. Ribosomes are found both free-floating and attached to the rough endoplasmic reticulum in eukaryotes and in prokaryotes.
c. Ribosomes are the sites of lipid biosynthesis in both prokaryotes and eukaryotes.
d. The ribosomes in the prokaryote are slightly larger than those found in the eukaryotic endoplasmic reticulum.
Answer:
C
Explanation:
Ribosomes are in Eukaryotic and Prokaryotic cells
I think this is correct
Ribosomes are the site for the protein synthesis. In eukaryotes, the ribosomes found in chloroplasts and mitochondria are 70 S ribosomes, which are similar in size to prokaryotic ribosomes. The correct answer is option a.
What is RER and SER ?It is the rough endoplasmic reticulum and the smooth endoplasmic reticulum.
Eukaryotes and the prokaryotes both got the DNA and the ribosomes as well. The ribosomes which are present in eukaryotes are 80 S and the prokaryotes have 70 S type of ribosome units thus the Mitochondria along with the chloroplast in the prokaryotes have their own ribsomes as well as DNA which is 70 S that is same to the prokaryotes.
Endoplasmic reticulum is the site of lipid synthesis and with that they do show the association with ribosomes for the protein synthesis but not in prokaryotes but that happens in the eukaryotes.

Which state of matter does this model represent?
A} solid
B} liquid
C} gas
D} plasma
The state of matter represented by the above image is a liquid (option B).
What is matter?Matter is the basic structural component of the universe. Matter usually has mass and volume.
Matter exists in three states namely;
Solid: the particles of a solid are very attracted to each other. They are close together and vibrate in position but don't move past one another.Liquid: In a liquid, the particles are attracted to each other but not as much as they are in a solid.Gases: In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don't interact with one another but just hit and bounce off of each other when they collide.Based on the particles of the substance in the image above, one can observe that they are closely but not tightly packed, which suits the description of liquid state.
Therefore, the particles of the substance in the model represent a liquid.

intraspecific competition.
resource partitioning.
commensalism.
Answer:
Explanation:
European starlings are agricultural pests. They damage crops and berries. European starlings also aggressively compete with native birds for the insects they eat. ... Large numbers of European starlings can cause dangerous and expensive damage to jet engines when they get sucked in.
The growing population of starlings has caused displacement of Eastern Bluebird from their normal nesting sites. This is an example of interspecific competition.
what is interspecific competition?Two models Lotka-Volterra model of competition and the Tillman’s model of competition are used to describe the influence of exploitative competition among species.
Interspecific competition is defined as in an ecosystem when different types of species compete among themselves for the fixed and same resources like food, shelter, light, water, and the other essential necessities.
In such one organism may lower its population size because of not able to avail the limited resources where as other organism increase in the population and they also tend to limit the growth of that particular species.
Thus, competition occurs in two ways either at an individual organism level, namely exploitative competition and interference competition.

How could increasing the number of plants help you decrease error in the experiment? Check all possible reasons.
It would increase the sampling error.
It would reduce the significance of any single measurement error.
It would make calculations easier.
Having more data would make the average height less affected by one or two plants that are randomly shorter or taller.
It would make a plant’s death less of an issue.
Answer: Increasing the number of plants in an experiment will help decrease the error, because you have more test subjects to run the test on.
Explanation:
The more subjects that you have have the more tests you can run, this will give you a chance to get more accurate and consistent results. When completing an experiment, you normally have to run 5 or more tests in order to get a goos set of data. So by increasing the number of plants you test on, you'll be able to get a better set of data.

which sphere regarding carbon would be the most immediately affected by a decrease in sunlight
Answer:
All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has stayed in the atmosphere. Eventually, the land and oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years.
The changes in the carbon cycle impact each reservoir. Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger.
describe the active site of an enzyme. why is it important?
Answer:
An active site contains a binding site that binds the substrate and orients it for
catalysis. The orientation of the substrate and the close proximity between it and
the active site is so important that in some cases the enzyme can still function
properly even though all other parts are mutated and lose function.
