So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).

So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function

The ABO blood group assorts independently of the Rhesus (Rh) blood group and the MN blood group. Three alleles, IA , IB , and i,

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN

Please help I’ll mark brainliest

nata0808 [166]

I think that it’s A, D, and F

-the particles do not have a charge
-movement across membrane doesn’t require additional energy
-the particles crossing could be oxygen or water
