Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of
the decomposition are hydrogen (H2) and oxygen (O2). Which of these changes to the cell would cause the greatest reduction in the activity of catalase?
A)
a decrease in the concentration of hydrogen and oxygen
B)
an increase in the concentration of hydrogen peroxide
C)
an increase or decrease in pH beyond normal range
Sexual reproduction happens when there is the involvement of two parents to give rise to the offsprings.
For the production of offsprings, each of the parents produces a haploid gamete and it is by the fusion of these two haploid gametes that a diploid organism is produced.
In the given situation, there are 19 chromosomes present in the haploid gametes this means that a diploid individual will have 2X19 = 38 chromosomes.
Now the underground stem cells are not gametes but somatic cells and the somatic cells are diploid and hence, they will have 38 chromosomes.
