Could a man with type B blood and a woman with type AB produce a child with type O blood?
Luda [366]

Answer:

The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Therefore, the child could not possibly be of blood type O.

sineoko [7]

Answer:

The correct statements that you must check are:

  • The oxygen atom has a greater attraction for electrons than the hydrogen atom does (second statement).

  • The electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms (fourth statement).

Explanation:

Electronegativity is the relative ability of an atom to pull the electrons in a covalent bond.

Hydrogen has an electronegativity of 2.20 and oxygen has 3.44. That means that oxygen attracts the electrons more strongly than hydrogen does (second statement).

As consequence, the electrons in the covalent bond H - O of water are not shared equally (fourth statement): the electron density will  be higher around the O atoms.

Of course, this discards the statement telling that hydrogen atom attracts electrons much more strongly than the oxygen atom, and the statement telling that hydrogen and oxigen have same electronegativity.

Such difference in electron densities creates a dipole moment, so you discard the last statement (that the water dipole moment is equal to zero).

How many cubic feet of air at standard conditions 1.00 atm are required to inflate a bicycle tote of .50 cu. Ft. To a pressure o
Alexeev081 [22]
As I am reading the problem, I see they gave you two pressures, one volume and they are asking for another volume. this should give you a hint that you need to use the following formula. 

P1V1= P2V2

P1= 1.00 atm
V1= 0.50 ft³
P2= 3.00 atm
V2= ?

Now we plug the values

(1.00 x 0.50)= (3.00 x V2)

V2= 0.17 ft³
