Answer:
By performing a test cross i.e. a cross with a recessive trait
Explanation:
According to the question, hairlessness is a recessive trait, meaning that it will only be expressed in a homozygous condition i.e. when there are two recessive alleles in the genotype. Presence of hair is dominant, meaning that it will mask the phenotypic expression of hairlessness allele in a heterozygous state. Hence, a dominant phenotype can either be homozygous (same dominant allele) or heterozygous (combination of dominant and recessive alleles).
In order to determine which of these genotypes the dominant phenotype possess, we perform a test cross. A test cross is a cross performed to determine the genotype of the dominant organism by crossing it with a homozygous recessive genotype.
Ideally, the offsprings resulting from the cross will all be phenotypically dominant if the organism in question is homozygous dominant but if the organism is heterozygous dominant, the offsprings will occur in an equal ratio of dominant to recessive phenotypes.
So in this case, all of offsprings of this cross between the rat terriers will possess hair if the dominant rat terrier dog is homozygous, but if the dominant rat terrier dog is heterozygous, an hairless offspring will be produced.
Answer: carbohydrates is composed of amino acids
Explanation: carbohydrate functions as an energy giving food in the body. Examples are rice, casssava and maize. The molecular structure of carbohydrate is (CH20)n. Carbohydrate has three subtypes:
(1) Monosaccharides: They are simple sugar and consists of a number of carbons(C) which ranges from 3 to 7.
(2) Disaccharides: They are formed when two Monosaccharides undergo a dehydration reaction which is also known as condensation reaction. thanks
(3) Polysaccharides: They consist of a long chain of branched or unbranched
Monosaccharides Monosaccharides linked by covalent bonds.
Carbohydrates is not composed of amino acids but rather protein is composed of amino acids.

Answer:
The correct answer is C the extraction of high energy electrons remaining from glycolysis and citric acid cycle .
Explanation:
Electron transport chain(ETC) occur in mitocondria and is the last process of aerobic respiration.ETC deals with the transfer of electron from the reducing equivalent such as NADH,FADH2 thereby oxidising them to their oxidized form NAD+,FAD.
The liberated electron from these equivalents utilizes the proton motive force come from the transport of H+ ion cytosol to mitocondrial matrix and then result in the phosphorylation of ADP to form ATP along with H2O by the reduction O2.
