ANTONII [103]
Carbohydrates are examples of food types or biomolecule utilised by living organisms to acquire energy amon other functions. They are classified into monosaccharides, disaccharides and polysaccharides. Polysacchrides conatin multiple monosaccharides joined together by bonds forming a long chain and a complex molecule, for example, chitin, cellulose and peptidoglycan. These polysaccharides exists as a set of long, parallel strand that are linked to one another, a feature that makes them act a structural molecules withstanding pulling and pushing forces well.

Which level of organization is characterized by a group of cells that work together to perform a common function? i need help wi
mamaluj [8]

Organization in organisms is like this:

cells => tissues => organs => organ systems => organisms

Since we are talking about a group of cells, this would be a tissue. Don't let the word 'function' confuse you. Tissues do functions as well as an entire organ or organ system.

It is helpful to use the flow chart when asked questions like these, so make sure to memorize it! It will be helpful in any level of science.

I hope this helps!

Mason drew the cladogram shown. Which statements best describes the cladogram? Select three options. (HURRY I WILL MARK BRAINLIE
Yuki888 [10]

Answer: Correct options B, D and E.

Explanation:

In the cladogram, we can see that in the first branch we have a division, one branch goes to fish and the other goes to a division (a division means a common ancestor)

Then the fish are the most primitive (being directly related to the first ancestor)., E is true.

We also can see that between fish and birds we have 3 separations (the ancestor in common is 3 "generations" behind), and between frog and birds we have two separations (the common ancestor is 2 "generations" behind), so frogs are more closely related to birds than fish.

So D is also true.

We also can see that the only pair that has only one ancestor in common are birds and reptiles, so the ones that are most closely related are birds and reptiles. B is also true,

Aidan has had non stop diarrhea all day and is severely weakened. why is his nurse concerned?
Sveta_85 [38]
Diarrhea can be caused by indigestion, a raw meal, or little bacterias found in almost anything we swallow, but if it doesn´t stop in a 12 hours period, it may be caused by some infection or a worse condition that need to be seen by a doctor, is this case, the nurse is concerned because Aidan is severely weakened, signal that is dehydrating very fast and that could cause him a worse condition such as hypotension, hypoglycemy or even losing consciouness.

Match each component of biodiversity to the example of how it contributes to ecosystem stability.
professor190 [17]

Answer:  

Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.

Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.  

Species diversity:  Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.  

Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.

Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.

Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.

Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.
