In the circulatory system, nutrients such as amino acids and glucose are transported by the PLASMA.
The plasma is the liquid portion of the blood and one of its most important function is to transport materials such as glucose, amino acids, hormones, enzymes, water, etc.
Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
Answer is A. Archaebacteria
Archaebacteria are a type of single-cell organism. They are a group of most primitive prokaryotes which are believed to have evolved immediately after the evolution of the first life. Thermoacidophiles are the archaebacteria which can tolerate high temperature as well as high acidity. They often live in hot sulfur springs where the temperature may be as high as 80°C and pH as low as 2. Examples are Thermoplasma, Thermoproteus.
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.
