It moves along straight lines in air and changes direction when it enters water. This is because of phenomenon of refraction which a ray of light experience when it moves from one medium to another medium. The light ray bends away from the normal to the surface if it travels from denser to rarer medium.

Name the four things that can happen to move carbon from a plant and return it to the atmosphere
kvv77 [185]

1. Respiration-process by which plants release CO, while they break down the sugar

2. Animals eat plants- They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.

3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground

4. Root respiration- respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass ).

Imagine that beak color in a finch species is controlled by a single gene. You mate a finch homozygous for orange (pigmented) be
AURORKA [14]

Answer:

A) incomplete dominance.

Explanation:

It is a clear case of incomplete dominance. This kind of inheritance shows deviation from Mendel's popular law of genetics which is known as "Law of Dominance". This law states that when two pure breeding parents i.e. homozygous dominant and homozygous recessive are mated then all their off-springs are genotypically heterozygous but phenotypically they all show dominant trait. But in incomplete dominance, <u>the dominant allele is unable to mask the expression of recessive allele completely</u> which leads to a phenotype which is a blend of both the traits.

In the example, orange beak is unable to mask the expression of ivory beak completely as a result of which all the off-springs have an intermediate trait which is pale, ivory-orange beak.
