Answer:
Incorrect
Explanation:
In the bone modelling process, osteoblasts a responsible for bone formation and osteoclasts are responsible for bone resorption. In the young adult during growth, the formation of bone exceeds the resorption of bone to maintain bone mass. Therefore,
As we get older, bone formation decreases due to reduction in osteoblastic activity and numbers and bone resorption increases as a result of sex hormone deprivation, this will result in decreased bone mass (osteoporosis). Therefore, osteoclastic activity would have to exceed osteoblastic activity in order or osteoporosis to develop

<u>The offspring are genetically unique. </u>
Answer: Option C
<u>Explanation:</u>
Meiosis is a form of cell division that is concentrated towards the reproductive cells. In this cell division the diploid cells (two sets of chromosomes) undergo reduction to form a haploid cell (one set of chromosome). The haploid cell produces sperms and eggs.
Meiosis occurs in two levels Meiosis I and II. Chromosomal segregation happens during meiosis I and II to produce a genetic diversity. The important net result obtained by the meiosis is to produce a genetically unique offspring.
