If two parents do not have widow's peaks, what is the probability that their child will have a widow's peak?

The solution is 0%.

In order to the parents not to have a widow's peak, they would need homozygous recessive. This is the only allelic combination where they lacked one dominant form of allele. All children will not have widow's peak because neither parent has the possible allele.

Their child can not have a widow's peak, seeing as widow's peak is a dominant trait. They need two recessive alleles to have a straight hairline, meaning none can be inherited by the child.

Hope this helps.

How osmosis works in the three fluid compartments of the body
PtichkaEL [24]

Answer:

Explanation:

In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane.

During which stage of complete cellular respiration is most of the atp produced?
Valentin [98]
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respirationoccurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate.

Which molecules prevent cell membranes from dissolving in water?
sertanlavr [38]

Answer:

The "tail" of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water. Following the rule of "like dissolves like", the hydrophilic head of the phospholipid molecule dissolves readily in water.

Nonpolar Fatty Acids

Which force primarily acts on a natural or artificial satellite to keep it in orbit around a planet
rjkz [21]

Answer:

Gravity

Explanation:

When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.

By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.
