Desalination: to remove salt from seawater

The biggest problem occurs in the species living in that habitat. Some species of fish survive better in salt water than in fresh water. Just about every species of fish you`ve seen in a tank need salt water to absorb. Removing salt from a natural environment will decrease those fish`s population.

In some aquariums, leaving salt in the aquariums is proven to prevent disease from the fish. It helps to clear the build up that living in fresh water can cause.

In the stable form of protein, the ________ is generally oriented to the interior of the protein molecule.

dimulka [17.4K]

Answer:

Hydrophobic part

Explanation:

A protein is made up of amino acids. Some amino acids such as serine and threonine are polar and hydrophilic in nature as they have polar side chains. The other amino acids such as alanine and proline are non-polar as they have nonpolar side chains.

The polar amino acids of a polypeptide chain are folded towards the inside of the protein to avoid any interaction with the surrounding watery medium. On the other hand, the polar and charged amino acids are oriented towards the surface of a folded protein. This arrangement makes the proteins stable.

Which of these sentences describe sources and preservation of genetic variation? Select all that apply.

saul85 [17]

Genetic variation can be defined as the difference in the DNA sequences between the individuals in the population

<u>Explanation:</u>

Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics,this sentence describes the source and preservation of genetic variation.
The Mutation is one of the genetic variation or disorder, and probably bacteria choose mutation to become repellent to antibiotics
In some of the cases of spontaneous bacteria have been obtained from other sets of bacteria through the process and make the bacteria repellent to an antibiotic.
They survive antibiotic treatment and increase in numbers by natural selection.
Natural selection can be stated as the process in which organism survive and reproduce adapting to the environment
