How codominant inheritance patterns differ from dominant/recessive inheritance patterns

1 answer:

3 0

Its simple dominant and recessive inheritance patterns and organism would need two recessive alleles(rr) for the trait to be expressed but only one dominant allele for that trait to be expressed (RR or Rr) however in the case of co-dominant alleles the heterozygous state (Rr) would produce a third phenotype rather that the dominant phenotype.

Surface tension ____. a. is the inward force which tends to minimize the surface area of a liquid b. may be increased by deterge

laila [671]

Answer:

Surface tension ____. a. is the inward force which tends to minimize the surface area of a liquid b. may be increased by detergents c. is decreased by hydrogen bonding d.

Note: option d is missing

The correct answer to the question is "option A (is the inward force which tends to minimize the surface area of a liquid)"

Explanation:

Surface tension is the most important for small fluid bodies. The surface comes under tension from the imbalanced forces and is often expressed as an amount of force exerted in the surface perpendicular to a line of unit length and it is a direct measure of energy loss per unit area of a surface.

The resistance that a surface shows against extension is a proof that an internal surface tension is present in the surface. Formula for measuring surface tension is: gamma equals force divided by length. The SI unit is newton per meter, dyne per centimeter is also used.

Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. Surface tension of a liquid surface is that property of that liquid surface that makes it act like a stretched elastic sheet. Example of effect of surface tension on water is the flotation of objects denser than water, the separation of oil and water due to tension which arises in surface between dissimilar liquids. In the surface tension of liquid, the net force of attraction acting on the molecule is zero.

If a ball of radius 0.1 m is suspended in water, density = 997 kg/m^3, what is the volume of water displaced and the buoyant for

densk [106]

Answer:

Part A

The volume of water displaced is 4.1887902 × 10⁻³ m³

Part B

The buoyant force is approximately 40.93 N

Explanation:

From the question, we have;

The radius of the ball suspended (barely floating) in the water, r = 0.1 m

The density of the water, ρ = 997 kg/m³

Part A

The volume of the ball = The volume of a sphere = (4/3)·π·r³

∴ The volume of the ball = (4/3) × π × 0.1³ = 0.0041887902 m³ = 4.1887902 × 10⁻³ m³

Therefore;

The volume of water displaced, V = The volume of the ball = 4.1887902 × 10⁻³ m³

The volume of water displaced, V = 4.1887902 × 10⁻³ m³

Part B

The buoyant force = The weight of the water displaced = Mass of the water, m × The acceleration due to gravity, g

The buoyant force = m × g

Where;

g ≈ 9.8 m/s²

The mass of the water, m = ρ × V

∴ m = 997 kg/m³ × 4.1887902 × 10⁻³ m³ = 4.17622383 kg

The buoyant force = 4.17622383 kg × 9.8 m/s² ≈ 40.93 N.

What would happen if the amount of light reaching the Earth from the sun were cut in half? Predict what the climate and life wou

kicyunya [14]

A lot would happen depends on which perspective you look at it from. Less incoming solar radiation means that there is a greater possibility of the surface temperature of earth reducing. there would be a cooling effect. And it could be major cooling in certain part of the world depending on milankovitch cycles. We know that the amount of light or solar radiation that reaches the earth is unequal in different parts of the world because of the obliquity, eccentricity, and precession of the earth. But, in general you would most likely see a cooling trend around the world and in some parts it would be extreme. In Canada or in the North is general, winters would become even more cooler or colder... winters would become longer perhaps, And summers would 've cooler. on the contrary to what most believe, you would most likely see a decline in precipitation such as snow or rain because this is mostly caused or intensified by warming temperatures. Life would be probably very similar to that of the Pleistocene epoch. how would humans respond to this change... Well most likely they would try to use their tech to control weather because they already do to a smaller proportion.

hope that helps a bit! :)
