Ans.
Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the offspring.
Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.
However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.
Many different ways, primarily through bone and muscle loss. The lack of pressure on bones causes the body to reabsorb calcium from them, weakening them and potentially causing kidney stones.
Explanation:
Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is
pH = -log[H+].
...where pH is -base 10 log of the concentration of hydrogen ions within the solution.
Initial volume= 20 mL
Final volume= 600 mL
# of dilutions=
= 30
for a pH 2= [H+]= 
∴ [H+]= 
and pH is an antilog of [H+]= - log 
∴pH = 3.47

Answer:
Following are the responses to the given question:
Explanation:
Increased
gases in the water may hasten photosynthesis, enabling crops to develop and grow more quickly. Some
is absorbed and more oxygen is expelled as the frequency of rate of photosynthesis.
The higher plants grown means greater water filtration. Natural selection will run its course if the water is less polluted, as well as the fish may not need to pass mostly on full-body plate characteristics to their descendants.
