Answer:
A. True
Explanation:
The result indicates that taking calcium has no effect on the development of osteomalacia in the women. This is because, of the over 120 women placed on the calcium supplements, it happens to be minimal number of people ( less than 20 people) that develop the osteomalacia disease of the bone.

Answer:
C. Prohase 1
Explanation:
It is during prophase 1 of meiosis that crossing over occurs before tetrads or homologues pair of chromosomes are alligned across the equator of metaphase 1. In Meiosis 11, only the sister chromatics will be left or remain and the homologues pair of chromosomes would be moved to separate cells.
The right answer is 34.78%
The interphase is the period of the cell cycle that the cell transcribes its genes and the chromosomes are duplicated. It can be subdivided into several phases:
* phase G1
* phase S: during which the chromosomal material is doubled by DNA replication. This is called chromosome duplication.
* phase G2.
Phase G1 is the longest phase of the interphase (its duration depends on the type of cell), followed by phase S, then phase G2.
To calculate the proportion of phase S in the interphase simply make the division:
phase duration S / interphase duration = 8/23 = 0.3478 (in percentage that is 34.78% (0.3478*100)).
