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
Answer:
The yeast is no longer active, Climate conditions, too much liquid, Wrong type and amount of yeast, Not adding or using too little salt, Insufficient baking time and Wrong oven temperature.
Explanation:
The yeast is no longer active, Climate conditions, too much liquid, Wrong type and amount of yeast, Not adding or using too little salt, Insufficient baking time and Wrong oven temperature are the factors that could fail the process of dough rising. For rising of dough, the environmental conditions and materials that is used in dough must be present in optimum range or quantity.
During mitosis the chromosomes are being duplicated. which means the chromosomes that are formed during the mitosis is identical to its parents. during the mitosis, the cell udergoes 4 phases. prophase, metaphase, anaphase and lastly the telophase
In order to study the formation of cancer cells, you should study the life cycle of normal cells as cancer cells are abnormal cells.
Actually, Normal cells grow, divides and died after an interval of time. And when this process is break down, cancer cells begin to form. They are usually old cells which don't die after their life cycle.
Hope this helps!
