Answer:
involves accumulation of rhodopsin
Explanation:
This is because dark adaptation is the ability of the eye to react to low light sensitivity and all the rod pigments of the eye bleached out which is as a result to the bright light and this make the rods nonfunctional in the initial state . Once you are in the dark, rhodopsin regenerates and tthis lead to increase in retina sensitive continuously.
Answer:
- The blood group of the father must be B.
- The genotype of blood group would be .
- The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be or .
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is .
The blood group of the father must be B with genotype in order to produce offspring with blood group O and B.
The correct answer is letter C, crop rotation is not a form of re-shaping farmland in order to conserve soil. Crop rotation refers to planting different kinds of crops in certain rotations in order to prevent the occurrence of different kinds of pests.
