The father's father donates only the Y chromosome, not the X chromosome. The father's mother gives him his X chromosome.

Therefore, the father's father does not pass on any of the genetics of his X chromosome

Answer:

Option). Father's father.

Explanation:

Humans are diploid organisms having 23 pairs of chromosomes (46 chromosomes). The 22 pairs of chromosomes are similar in both male and female, while the 23rd pair of chromosomes in male has one X and Y chromosomes and 23rd pair of  chromosomes in female has two XX chromosomes.

During reproduction, a man provides Y chromosome to his son and X chromosome to his daughter, while female provides X chromosomes to son and daughter.

Hence, the father's father of a woman would provide only Y chromosome to his son (woman's father), which could not be a source of any X chromosome's gene of that woman.

Thus, the correct answer is option). father's father.

Which element would you expect to have a full valence shell?
kipiarov [429]

Answer;

-Noble gases or Group 18 elements

Explanation;

A full valence shell is the most stable electron configuration. Group 18 elements or noble gases such as helium, neon, and argon, have a full outer, or valence, shell. Elements in other groups have partially-filled valence shells and gain or lose electrons to achieve a stable electron configuration.

They are extremely unreactive and do not form bonds with themselves. Solid helium is the the ultimate fine powder being monotomic.

kondaur [170]

Answer:

promote stomatal closure during drought stress.

Explanation:

Abscisic acid inhibits the growth and stomatal opening, specifically when the plants are exposed to some stress conditions. Abscisic acid also regulates the seed maturation and seed dormancy. ABA concentration in leaves increases multiple folds under drought conditions. Its accumulation in leaves promotes closure of stomata and prevents the water loss by transpiration. ABA is required to restore the turgor pressure under drought conditions by stimulation of stomatal closure.
