Let assume one of option is - decreasing adhesive forces in between the water molecules and the glass due to mineral solution.

Explanation:

Adhesive force is the attraction of two different types of atoms or the molecules of unlike substances. Water and glass molecules are not similar as water is not having charged molecules like the glass molecules. Water molecules are attracted to glass molecules that are charged due to adhesive force.

Treating the glass with mineral solution decreases the adhesive force which leads to forming drops instead of the puddle.

Thus, the correct answer is -decreasing adhesive forces in between the water molecules and the glass due to mineral solution.

It is caused by changes in the sun’s position in the solar system. It is because the days in winter are shorter which has a change a change in the position from the sun.

The answer is D.

Explanation:

Apart from the signals that cells receive from the DNA for division timing, another factor that determines when cells divide is their size. As the cell grows, it's circumference increases accoring to the formula $2\pi r$ but it's volume follows the area formula mathematically which is $\pi r^{2}$ and this leads to surface area of the cell to increase faster than its volume, leading to problems such as feeding, transportation of materials within the cell etc. So the answer to the example given in the question is D.

C. Is a Factual Statement

This one is tricky, because scientific law can explain an observation, or be used to make a prediction, but I believe that C. is the most correct of the 4 answers.

Female mammals undergo X-chromosome inactivation during early embryogenesis, thereby females are mosaic for the expression of X-linked genes

Explanation:

In mammals, males receive only one copy of the X chromosome and one Y chromosome, while females receive two copies of the X chromosome. The X chromosome contains approximately 1,000 key genes involved in development. In human female embryos, one of these two copies of the X chromosome is inactivated to prevent the imbalance caused by a double dose of X-linked genes, a phenomenon known as X-chromosome inactivation. The inactivation of one X-chromosome is a random process, thereby female cells are mosaics for all heterozygous X-linked alleles, where some embryonic cells have an inactive maternal X chromosome, while other cells have an inactive paternal X chromosome.

The question is incomplete as it does not have the options which are:

1) Several sperm fertilized the egg, so the fertilized  egg contained more genes from their father.

(2) More genes are inherited from the sperm

cell of their father than from the egg cell of their mother, so most traits will be like those of their father.

(3) More genes from their father are expressed  in traits that can be seen, and more genes from their mother are expressed in traits that cannot be seen, such as blood type or  enzyme function.

(4) Genes from their father are stronger than genes from their mother, so the genes from  their mother are not expressed.

(3) More genes from their father are expressed  in traits that can be seen, and more genes from their mother are expressed in traits that cannot be seen, such as blood type or  enzyme function.

Explanation:

In the given question, the traits of a father are expressed in older age as compared to a younger age.

This could be explained by the fact that the genes from the father are expressed in the trait which is observed during older age but the genes of the mother are expressed in the traits which are not observed during the older age.

This is not true that the genes of a father are more dominant then the mother and the genes of the only mother are transferred.

Thus, the selected option is correct.

D. Sediments are carried from place to place.

Weathering is the process of breakdown of rock or soil particles into sediments by the effect of wind, water or chemical agent. Erosion is the process of removal or displacement of finely grained surface or sub-surface soil by the effect of wind, water or any other agent. In both weathering and  erosion, the sediments are displaced to the location other than the one where their parent rock originated. Therefore, sediments are carried from place to place. Hence, the composition of sediments will be different from the composition of the underlying bedrock.

C. Visible light does not produce transitions between electronic energy levels in the N₂ molecule but does produce transitions in the I₂ molecule.

Explanation:

Abortion of light by molecules will produce electronic transitions from a ground level to a higher level equal to the energy of absorbed light.

In the case of nitrogen (N₂) the allowed electronic transitions are between electronic energy levels with a energy difference equal to the energy of photons of the ultraviolet light. Nitrogen will not absorb from the visible range so it is colorless.

Now iodine (I₂) have the allowed electronic transitions between electronic energy levels with a energy difference equal to the energy of photons of the visible light. As a consequence Iodine vapors have a violet color.
