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.

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.

Answer:

Unity is the other name of cohesion.

Explanation:

The property of cohesion is to sticking together of something. The molecules of liquid stick together with the help of cohesion. This cohesion property  is very important for plants because with the help of this property, plants take water through roots from the soil and the water molecules are stick together with the help of cohesion. If cohesion is not present then the uptake of water can not be possible.

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.

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.

Answer:

cells are the smallest structural units of living matter and compose all living things.

Explanation:

fact

matter is everything (living and non living)

cell is the basic unit of organism (living)

so cell is part of matter cause matter compose everything int the universe

cells are the basic small and structural units of living matter and composed of organelle mostly made up of biomolecules.

Cell is the basic structural unit of any living system, present in animal, plant, microbes etc where Bacteria are unicellular in nature as it is composed of single cell, higher eukaryotic organisms are multicellular like plants and animal cell as it is made up of multiple cells.

The prokaryotic cells are simplest cell which have a cell membrane, cytoplasm and other cell organelles where the metabolic processes occur, ribosome is the organelle where protein synthesis occur, and nucleoid carry genetic information, reproduce by binary fission.

The eukaryotic cells are more complex which have cell membranes, cytoplasm, ribosomes, and nucleus, rough endoplasmic reticulum, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.

Answer:

Dependent variable: number of apples

Explanation:

In an experiment, the independent variable is the variable that isn't modified by the other variables measured in the experiment. In the example above indicated, the independent variable is the fertilizer used in the experiment. On the other hand, the dependent variable is the variable tested or measured in the experiment, thereby this variable is 'dependent' of the independent variable.

Answer:

monosaccharides

Explanation:

Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.

Answer:

The most common polysaccharides are built solely with glucose monomers, while significant structural differences between these polysaccharides arise mainly from the position and number of the glycosidic linkages in each glucose unit.

Evolution

Explanation:

Evolution is the change that occurs to a particular species of a population from generation to generation. This change is due to the alteration in their genetic composition, which is inherited over time.

However, this change do not occur at the individual level but rather it occurs to a population i.e. only a POPULATION undergoes evolution process not individual organisms. Note that, the other options including genetic code, growth and development, response are controlled individually by the organism, however, the evolution process takes time and occurs over a population rather than to individuals

Answer:

Cellulose.

It's structural polysaccharide in plants

Cellulose is a polysaccharide often responsible for providing structure to plants

Option B is correct.

Cellulose is a polysaccharide that is made up of glucose molecules that are linked together in a long chain. It is the most abundant organic compound on Earth, and it is found in the cell walls of plants. Cellulose provides structure to plants, and it also helps to protect them from damage.

Amylose is a polysaccharide that is also made up of glucose molecules, but the molecules are linked together in a different way than they are in cellulose. Amylose is found in starch, and it is not as strong as cellulose. Therefore Option B is correct.

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.

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.
