if cells are placed in pure water, will water will move intothe cells faster than it will move out of the cells?

1 answer:

8 0

If the concentration inside the cells is the same as outside (water) than it should move at the same rate. Only if the cell's concentration in the inside is more than it is on the outside is when water would move faster going in.
Hope this helps(;

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

For most athletes, the period in their yearly training cycle during which it is recommended to begin calorie restriction so as to lose significant amounts of stored body fat is the off-season or early in the preseason. Restriction of energy intake late in the preseason when there is rigorous training or during season when there is competition may impede training, recovery, or performance.
