The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".

Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.

A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozy

Fantom [35]

Answer:

Explanation:

A woman with type A blood (whose father was type O) meaning her genotype is AO mates with

Man that has type O blood (OO genotype)

Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.

Cross

A O M N H h

O AO OO M MM MN H HH Hh

O AO OO N MN NN h Hh hh

Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4

Type A with M antigen:

1/2*1/4*3/4 = 3/32

Type A with M and N antigens:

1/2*1/2*3/4 = 3/16

Type A with N antigen:

1/2*1/4*3/4 = 3/32

Type O with M antigen:

1/2*1/4*3/4= 3/32

Type O with M and N antigens:

1/2*1/2*3/4 = 3/16

Type O with N antigen:

1/2*1/4*3/4 = 3/32.

The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).

Consider the arteriolar end of a capillary bed. During capillary exchange, the process of __________ is favored at the arteriola

krok68 [10]

Answer:

Consider the arteriolar end of a capillary bed. During capillary exchange, the process of filtration is favored at the arteriolar end due to the higher hydrostatic pressure.

Explanation:

The net filtration pressure at the arteriolar end of the capillary bed is more than 10mmHg. That is why the fluid exits capillary since capillary hydrostatic pressure is 35mmHg that is greater than blood colloidal osmotic pressure which is 25mmHg.

Hence during capillary exchange, the process of filtration is favored at the arteriolar end due to the higher hydrostatic pressure.
