The answer would be B.

H2O is polar and forms hydrogen bonds with itself but O2 is nonpolar and can only form weak(van der waals) interactions.

Answer: Option B

Explanation:

The molecules that is described in the model is water H_{2}O and other molecule is O_{2} molecule.

Due to difference in electronegativity of hydrogen atom and oxygen atom there is partial positive charge on each hydrogen atom and partial negative charge on oxygen atom of O_{2} molecule.

Hence, water is a polar molecule.

Whereas in O_{2}, there is covalent bonding due to sharing of electrons. Hence, this molecule is covalend and hence, it is neutral in nature.

Therefore,  O_{2} is a non-polar molecule.

So, both the molecules are put together in the container then there will be no attraction in between them because water molecules contains charge but oxygen molecules does not contain any charge as they are neutral.

Thus, we can conclude that one molecule is polar and other is non polar so they do not attract each other.

Frameshift mutations ____________.
castortr0y [4]

Answer:

The correct answer is option b. "cause a change in the reading frame of mRNA codons".

Explanation:

Frameshift mutations are among the most drastic mutations because in most cases, result in the translation of a completely different protein. Frameshift mutations are the result of insertions or deletion of one or more nucleotides, resulting in a change in the reading frame of mRNA codons. In consequence, the ribosome translates a different amino acid sequence, based on the new reading frame of mRNA codons.

A population in which the frequency of alleles remains the same over generations is said to be in genetic equilibrium. Describe
DochEvi [55]

Answer:

Natural selection disrupts the genetic equilibrium by favoring the genes for the traits that impart survival advantage to individuals.

Explanation:

Natural selection refers to the unequal survival rate of individuals of a population due to the presence of some beneficial adaptive genetic trait. These individuals are able to survive more and leave more progeny. Over generations, the population has increased number of these individuals leading to evolution of a population with different allele frequencies.  

For example, the frequency of gene for antibiotic resistance in the bacterial population was increased once humans started using antibiotics to control the bacterial population. This led to the evolution of the bacterial population with antibiotic resistance.
