Im not sure but if there was a graph maybe
Answer: Option (a) is the correct answer.
Explanation:
A water molecule contains two hydrogen atoms and one oxygen atom. The chemical formula of water is
.
Here, hydrogen is electropositive whereas oxygen atom is electronegative in nature. Hence, oxygen atom pulls electrons from hydrogen atom and as a result partial positive charge develops on hydrogen and partial negative charge develops on oxygen atom.
Therefore, molecule of water becomes polar in nature.
Thus, water is considered a polar molecule because it has partial positive and negative charges at each end.
Answer:
By checking the proportion of those affected by the trait in relation to gender within the population of the offspring
Explanation:
If a trait is sex linked, such trait will be found more in the male sex compared to the female sex within the population.
The male has XY chromosome and as such only needs a copy of the affected allele in order to be affected for the trait. A female has XX chromosome and as such needs two copies of the affected alleles in order to be affected for the trait.
Hence, the proportion of affected male always outweigh the proportion of affected female in a population as far as sex-linked trait is concerned.
<em>Consequently, a scientist might be able to determine whether a trait is sex-linked by observing the proportion of male to female affected by the trait within the offspring's population.</em>
The last one is the correct answer I do believe
