I think it'd be B.. I might be wrong tho..
Answer:
1. The parents genotypes could have been BO and AO
2. wire-hair
Explanation:
There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:
Blood type possible genotypes
Type A AA, AO
Type B BB, BO
Type AB AB
Type O OO
Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO for them to be able to produce a child with OO. a cross between these two could give rise to OO.
Question 2
Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).
thus, in a cross between homozygous wire haired and smooth haired, we will have:
homozygous wire haired homozygous smooth haired
P gen SS x ss
F1 gen. Ss
phenotype: wire haired
Plant #1 would locate in a damp and probably contain no undergrowth. Example forest.
Plant #2 would locate in a dry area such as a desert example cactus, as the waxy coating keeps water and the spines suck up water and protect the plany
Answer:
The correct answer is (a) to ensure that natural resources are available for future generations.
Sustainable development means optimized use of natural resources to meet the demand of people in the present and future scenario. The main aim of sustainable development is to balance our economic, environmental and social needs which allows the prosperity for now and future generations. Sustainability can only be maintained when the resources are used in a way that it meets the need of people, not the greed of people.This is done to ensure that natural resources are available for future generations.
