The discovery of multipotent cells is valuable because multipotent cells have the ability to specialize and heal greatly damaged tissues. Multipotent cells are stem cells that have the capacity to self-renew by dividing and to develop into multiple specialized cell types present in a specific tissue or organ.

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

Which of the following is a main difference in cell structure between an onion cell and a human cheek cell? A. An onion cell con
USPshnik [31]
The correct answer is "C".

Onion cell is a plant cell and human cheek cell is an animal cell. Hence, onion cell has a cell wall<span> but not in human cheek cells because animal cells do not have cell wall. Both cells have single nucleus. Since, human cheek cell is an animal cell, chloroplasts are cannot be seen in the human cheek cells.</span>

Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then,
Sveta_85 [38]

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.
