In ducks, the trait for normal feathers is dominant to the trait for silky feathers. If
vesna_86 [32]

Answer: The genotype ratio is 2Ff : 2ff

The phenotype ratio is two normal feathered birds to two silky feathered birds.

Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.

A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.

Which of the following is NOT a part of an ATP molecule? Select one: a. adenine b. ribose c. chlorophyll d. phosphate
Gnesinka [82]

Answer:

C (Chlorophyll)

Explanation:

Adenosine triphosphate (ATP) is an energy carrying molecule in all living cells. It is the usable form of energy by cells. Organisms are able to carry out cellular functions using the energy carried by ATP molecules. ATP like other molecules is made up of components that make up its chemical structure.

ATP is composed of three structural components; A five-carbon sugar called RIBOSE at the core of its structure, attached to a nitrogenous base called Adenine and phosphate group (three in ATP). The energy in ATP is released when it loses its phosphate component.

Chlorophyll is a pigment found in the Chloroplast of plant cells. It is another molecule that is made up of its own components e.g nitrogen, magnesium etc.
