a man with blood group A marries a woman with blood group O and their daughter has blood group O. Is this information enough to
Nonamiya [84]
This information is not enough to tell which of the traits-blood group A or O is dominant.
It is known that blood groups A and B are codominant, which means both will express if found together in a heterozygote. However, blood group O is recessive. But from this information, you can conclude that blood group O is dominant. Why is that so?
Let's imagine that father's genotype is AA and mothers' genotype OO and cross them:
Parents:               AA    x    OO
Offspring:      AO    AO   AO    AO
Since we have information that daughter has blood group O, we can conclude that O is dominant over A and mask it. This is not true! In this case, the daughter will have blood group A.

Mother's genotype surely is OO (because O allele is recessive, so to express a recessive trait both alleles must be recessive). But, the father cannot be AA, because it must give O allele to the daughter so she can have genotype OO and blood group O. So, the father's genotype is AO.  Let's take a look at that crossing:
Parents:         AO   x    OO
Offspring:   AO   AO   OO   OO
Thus, in this case, daughter can have genotype OO and blood group O.

The greater the concentration of sulfur and nitrogen oxides, the higher the pH of precipitation. True False
OLEGan [10]

False

Nitrogen and sulfur dioxide are acidic oxides in nature. The burning of fossil fuels and other sources are responsible for addition of these oxides in the atmosphere of earth. These oxides mixed with water vapor causes acid rain. Being acidic in nature they will have low pH value. Therefore, greater the concentration of sulfur and nitrogen oxides, will lower the pH value of precipitation.

hope this helps:)sorry if it doesnt

Which two statements are true for the leading strand in DNA?
melomori [17]

Answer: The correct options are statement first and fourth that is -

It is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction.

Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA.

The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.
