1 answer:

3 0

Organisms living in aquatic environments are affected by physical factors like temperature, salinity, the force of the waves and the availability of light. These factors can limit the dispersal of organisms in the ecosystem.
Biotic factors like competition and predation can also limit the living areal of certain organisms. Organisms can competitively exclude other in certain habitats and some organisms can be limited by the presence of predators.

Dvinal [7]

Answer:

A combination of polypeptides and modified sugars that enclose the entire eubacteria.

Explanation:

A component of bacterial cell walls called peptidoglycan (PGN) promotes innate immune responses. Peptidoglycan, a polymer made of sugars and amino acids, creates the cell wall of the majority of bacteria by producing a layer that resembles a mesh outside the plasma membrane. N-acetylglucosamine and N-acetylmuramic acid residues are alternated in the sugar component. forms a saccules in the cell wall of most bacteria that resembles a bag. It controls bacterial cell shape and is crucial for osmotic stability. A heteropolymer made up of glycan strands carrying small peptides is known as a peptidoglycan.

A jar contains 26 fluid ouncesbof spaghetti sauce. How many cups of spaghetti sauce do 4 jars contain

JulijaS [17]

____________________________________________________

Answer:

Your answer would be 13 cups of spaghetti sauce.

____________________________________________________

Explanation:

Lets break down this question to make the answer easier:

8 ounces = 1 cup

We are going to use the above to help us solve this question.

In your question, you have 26 ounces, and you would have four cups. You would need to calculate how many ounces are in the 4 cups

To do this, you would multiply 26 by 4:

26 × 4 = 104

The four cups have a total of 104 for ounces. But, you are not done solving yet. You need to found how many cups there are. We would be going to use the 8 ounces, since we know that is the amount of one cup, and use that to divide 104, since we need to distribute the amount of ounces to the cups.

You would divide 104 by 8

104 ÷ 8 = 13

There would be 13 cups of spaghetti sauce in 4 jars of spaghetti sauce that has 26 ounches in it.

Your FINAL answer would be 13.
