Answer:
Cystic fibrosis mutation is recessive to normal allele because only one functional or normal allele is enough to produce a functional protein. So, if mutation is present in one allele then also, a normal protein can be made from normal allele. The presence of normal protein prevents the expression of disease.
In addition, mutated allele only results in the loss of function of protein which can be compensated by the expression of normal allele. It does not add any toxic effect to the protein. Consequently, the disease is inherited in autosomal recessive fashion.
In contrast, Huntington mutation not only alters the structure of the functional protein but also adds toxicity to it. The altered protein is enable to interact with 100s of other proteins and inhibit or decrease their function. So, if only one allele is present then also, the mutated protein will be produced and it will result in the phenotype. Consequently, it is inherited as autosomal dominant fashion.

Answer: (1) Providing an optimized orientation of the substrate.
(2) Decreasing the ∆G in reaction.
(3) Excluding excess water.
Explanation: The active sites of enzymes increase the rate of reaction because they decrease the activation energy of the reaction,and the physical microenvironment provides an optimal orientation of the substrate relative to reactive functional groups while excluding excess solvent,such as water.
Although some active sites may have amino acids that form salt bridges with the amino acids from a substrate,not all do, so this is not a generic strategy of active site microenvironments

Answer:
Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. ... The second pump delivers oxygen-rich blood to every part of your body. Blood needing more oxygen is sent back to the heart to begin the cycle again.

Answer:
The dominant allele will be expressed.
Explanation:
When both alleles are present in the genotype, the dominant allele "masks" the recessive allele so that only the dominant trait is expressed.
