Answer: CALCIUM

Amino acids are organic molecules that, when linked together with other amino acids, form a protein. Amino acids are essential to life because the proteins they form are involved in virtually all cell functions. Some proteins function as enzymes, some as antibodies, while others provide structural support. Although there are hundreds of amino acids found in nature, proteins are constructed from a set of 20 amino acids. Generally, amino acids have the following structural properties:

A carbon (the alpha carbon)

A hydrogen atom (H)

A Carboxyl group (-COOH)

An Amino group (-NH2)

A "variable" group or "R" group

All amino acids have the alpha carbon bonded to a hydrogen atom, carboxyl group, and amino group. The "R" group varies among amino acids and determines the differences between these protein monomers. The amino acid sequence of a protein is determined by the information found in the cellular genetic code. The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acids. These gene codes not only determine the order of amino acids in a protein, but they also determine a protein's structure and function.

Savannas and temperate grasslands are very similar biomes. The answer to which question would NOT be helpful when distinguishing

nataly862011 [7]

Answer: Are there many herbivores living in the biome ?

Explanation:

The Savannas and the temperate grasslands are very similar in nature. Their temperature and rainfall patterns are very much similar.

The biome is recognized by the temperature and amount of rainfall in the area. These two factors helps in determining the types of trees and types of animals found there.

Is there huge amount of rainfall, is there wet season thought out the year, is there dry season, less rain or more rain, average temperature are some of the useful questions to know about biome.

If thy stop reproducing then the whole population could die and (3) is just crazy.
(4) is also inncorrect because of they run out of foo then they all will die.

What conditions cause the vacuole to fill with water.

Pie

Answer:

I don't think that's a condition, the vacuole is like a storage area so it would make sense for it to store water.

Olenka [21]

Answer:

Shape

Explanation:

Proteins are made up of amino acids. The amino acid sequence in a protein is determined by the nucleotide sequence present in the DNA of the cell. These amino acids join together and makes the primary structure of protein which fold by making hydrogen bonding and determines the shape of the protein.

The shape of the protein determines the function of that protein. If the shape and structure of the protein gets destroyed then the protein will lose its function. Change in pH, temperature, salt concentration, etc can change the shape of protein and make it functionally inactive.
