Answer:
The correct answer is - 6.8950.61 gm per mole
Explanation:
Given:
One form of hemoglobin is 0.324% Fe by mass
1 hemoglobin = 4 Fe
Solution:
Molar Mass of iron = 55.85
mass of 4 iron atom = 55.85 * 4 = 223.4 gms
0.324 % correspond to 223.4 gms
100 % correspond to = 223.4 *100/0.324 
= 68950.61 gm
MM of haemoglobin = 68950.61 gms = 6.8 E4 gms

Answer:
Prophase 1
Explanation:
Prophase I :It can be divided into five stages:
1)Leplotene: In this stage, chromosome becomes visible and shorten as a single structure. 
2)Zygotene: Homologous / sister chromosome pair up. This process is known as synapse. Synapse is the process of attachment of homologous /sister chromosome. One pair comes from the male parent while the other comes from the female parent. 
3)Pachytene: Bivalents shorten. 
4)Diplotene:Point of attachment of non-sister chromatids. The two chromosomes are seen to be joined at several points along their length. These points are known as Chiasmata.(Chiasmata, a cross). The paternal gene A, B, C may swap for the maternal gene a, b, c for instance, leading to a new gene combination in the resulting chromatids. This is referred to as *CROSSING OVER*. 
5)Diakenesis: Homologous centromere move apart. 
 So, crossing over occurs in *Prophase 1.
