I think the correct answer from the choices listed above is option D. <span>Astronauts and scientists conduct research studies aboard the International Space Station in a satellite that was built by sixteen nations. Hope this answers the question. Have a nice day.</span>
        
                    
             
        
        
        
1. Distance from the Earth to the Sun
2. Hurt your hand from the reaction force (Newton's 3rd law is every action has an equal and opposite reaction)
3. The Earth to rotate slightly slower (I think)
Hope this helps :)
        
                    
             
        
        
        
Why is your question in Biology section, it should be in mathematics or in physics but that's OK
The answer of A is - 21.6666666666 or 21.7 
The answer of B is - 21.6666666666 or 21.7 
the answer of A and B are equal because speed and velocity is the same thing 
 
        
             
        
        
        
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
 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.
 in order to produce offspring with blood group O and B.
 
        
             
        
        
        
The external crystal form of a mineral Rounded: Any clast with smooth edges. Usually indicates abrasion by moving water or wind. Also the answer to this question is in magmas/ lavas many mineral grains are growing  simultaneously. These grains grow into one another and form an interlocking texture.
