Answer: The liver

Explanation:

Gluconeogenesis is a process by which glucose molecules are produced de Novo (from non carbohydrates precursors such as lactate, glycogenic amino acids, and glycerol).

Only the liver can replenish blood glucose through glycogenolysis and gluconeogenesis.

During prolonged fasting or starvation the protein catabolism is speeded up to provide precursors (glucogenic amino acids) for gluconeogenesis.

Gluconeogenesis occurs mainly in the liver because one of the key enzyme glucose-6-phosphatase needed for glucose synthesis is only present in the liver.

Compare and contrast protozoan cysts fungal spores and bacterial endospores
docker41 [41]

Bacterial spores or endospores are not for reproduction. They do not improve the total number of bacterial cells. Whereas for fungal spores, they are formed from aerial hyphae. They can either be asexual spores which when germinated will be a new but genetically identical to the parent. Sexual spores result from the combination or mixture of nuclei from two opposite mating strains of the same species.

In a genetic cross between two flowering plants that are heterozygous for the color trait, red flowers (R) are dominant to white
deff fn [24]
Red flowers if homozygous dominant genes are prsent like RR and multiply with recesive gene which is ( rr) Rr × rr = (Rr Rr rr rr )half r red and half r white. If red flowers are homozygous dominant genes like RR × rr = (Rr Rr Rr Rr )all are red flowers

One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60
marta [7]

Complete question:

In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)

Answer:

Distance between genes → 12.5 MU = 12.5 cM.

You will find the complete explanation in the attached files due to technical problems.
