The difference in air pressure which is created by the molecules in air help to move kite up into the air.

Explanation:

When air moves faster, pressure of air becomes less. Air moves at a faster speed above the kite than below it and so its pressure is less on top of kite. The air pressure below kite is less. This difference in pressure results in uplifting of kite. Molecules of air with high pressure exerts more force on kite from bottom and thus pushing it up in air.

The greater is the difference between air pressure above kite and air pressure below kite, greater is the amount of force exerted on kite and hence, it reaches a greater height.

The molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of DNA se

Greeley [361]

Answer:

In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously.

Explanation:

Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.

This clock does not measure any time but the number of mutations, and other changes over certain time. Sometimes its useful property might be limited due to the highly diverged lineages.

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).

How does the four subsystem of the Earth connectwitheach other?

DiKsa [7]

The geosphere has four subsystems called the lithosphere, hydrosphere, cryosphere, and atmosphere. Because these subsystems interact with each other and the biosphere, they work together to influence the climate, trigger geological processes, and affect life all over the Earth.
