Answer:
The offsprings of this punnet square will be Dd, Dd, dd and dd in a ratio 1Dd : 1dd

Explanation:
This question involves a cross involving a single gene with alleles D and d where allele D is dominant over allele d i.e. D will mask the phenotypic expression of d in a heterozygous state.
This cross is between a heterozygous parent (Dd) and a homozygous recessive parent (dd). Parent Dd will produce gametes D and d while parent dd will produce gametes d and d.
Using these gametes in a punnet square, four possible offsprings with two distinct genotypes will be produced. The genotypes are: Dd and dd in a ratio 1:1
Hence, the possibility of having a heterozygous dominant offspring is 1/2 while the possibility of having a homozygous recessive offspring is also 1/2.
Well usually the source for all three (organs to a certain extent; 1 Kidneys, portions of liver, 1 Lung, Skin and or hair) can be taken from a live donor. This usually preferred.
However certain organs such as the heart, or any organ in particular can be gotten from a donor who has experienced brain death to the point where they are clinically dead
Answer: Didn't quite understand but if you mean plant biology then, ' Plant biology is the lab science area of plant study although they may spend some time in the field collection samples and taking records of plants in their natural habitats. It requires not only an understanding of a plant's biology but also its chemistry. This will include its genetic coding.'
Answer:
The correct answer is option d. "begins the production of a new glycogen molecule with the reactions of glycogenin".
Explanation:
As the name implies, glycogenesis is the process at which glycogen is synthesized. This process takes place by binding and addition of multiple glucose molecules. Glycogenesis begins the production of a new glycogen molecule with the reactions of glycogenin, an enzyme that acts as a primer and catalyzes the polymerization of the first few glucose molecules.
Answer: The answer to the question is D
Explanation:
The skeletal systems composed of the bones and network of tendors, ligaments and cartilages that connects and fasten the bones together. The skeletal systems are grouped or divided into two, namely the Axial and the appendicular, The system provides the stroctural supports for the human body and also safe guard the various organ fron damage. The system serves other vital functions.
