spores are light & small & encapsulated
The spores are very resistant to the the external environment since they are encapsulated structures , this type of dispersal helps past against natural calamities and promotes more living of the plant in further generations in extreme conditions . Since they are light weight and have small size they can be dispersed easily so helps in diversification of the plant in the area . These advantages are not well suited for sperms. Moreover, in mosses, the sperm requires water for the movement to meet the ova cells to make zygote.

Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
Answer:
The answer is - True
Explanation:
It is true that according to research the genes that affect energy balance in the body effectively promote energy intake and weight gain but are inefficient to promote energy expenditure and weight loss. This is because it is likely to be a polygenic condition such that there are numerous genes in interaction. Therefore the genes that promote energy intake and weight gain are insufficient to promote weight loss and energy expenditure which is the required energy to carry out physical activities such as breathing, exercising, etc.
