Explanation:

Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)

skelet666 [1.2K]

Answer:

Option C

Explanation:

Image for the question is attached here

Solution

It is given that the membrane is permeable to both salt and water.  

Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.  

As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.  

Thus water will move from side A to side B and Salt will move from side B to side A.

Hence, option C is correct

Protect the DNA’ basically means that the nucleotide sequence that makes up the gene has to be conserved because it is the ‘spec
kakasveta [241]

Answer:

True

Explanation:

A DNA molecule is composed of the nitrogenous bases stacked inside the two backbones made up of the phosphate and sugar molecules. The nitrogenous bases form the nucleotide which when read in the triplets called codons code for specific amino acid and then form proteins.

If we say that we have to protect the DNA than it means that we have to conserve the DNA molecule. Conserving the DNA molecule means that the sequence of nucleotide which codes for specific proteins must be conserved as it is the protein molecule that is essential for survival.

Thus, true is correct.
