cell differentiation is the result of gene expression. genes can be regulated several ways. for example, small interference rna molecules (sirna), prevent gene expression by binding to the product of transcription. how do sirna molecules silence genes?
Small interfering RNA (siRNA), also known as short interfering RNA or silencing RNA, belongs to a class of double-stranded gene non-coding RNA molecules with an average length of 20–24 (normally 21) base pairs.
It functions within the RNA interference (RNAi) pathway. Because the effect is only temporary, particularly in cells that divide quickly, gene knockdown by transfection of siRNA is frequently disappointing. Making an expression vector for the siRNA could help to overcome this. A brief loop is added to the siRNA sequence between the two strands. Short hairpin RNA (shRNA), the resultant transcript, can be converted by Dicer into a useful siRNA in the manner it usually does.

A certain type of congenital deafness in humans is caused by a rare autosomal dominant gene. In a mating involving a deaf man and a deaf woman, could all the children have normal hearing
It is possible that all the children from a mating involving a deaf man and a deaf woman could have normal hearing, but it is not guaranteed.
Autosomal dominant genetic disorders are caused by a single copy of a mutant gene, inherited from one parent. In this case, both parents are deaf due to having inherited the mutant gene from one of their parents.
If both parents pass on the normal version of the gene, the child will have normal hearing. However, if either parent passes on the mutant gene, the child will also have the disorder. The probability of inheriting the normal version of the gene from both parents is 25%.
So, it is possible that all the children from a mating involving a deaf man and a deaf woman could have normal hearing, but there is a 75% chance that at least one of the children will also have the disorder.

Which of these would likely be the most immediate result if oxygen levels in the Bay decreased by 90%
If oxygen levels in the Bay dropped by 90%, the most obvious effect would probably be a decline in fish numbers.
All of the Chesapeake Bay's living things, including the fish, crabs, and worms that burrow into the muddy bottom, require oxygen to thrive just like people do. The majority of scientists concur that dissolved oxygen levels in the Bay must be at least 5.0 mg/L for organisms to survive and grow. However, an animal's oxygen requirements vary based on its size, complexity, and environment.
Worms and clams require dissolved oxygen concentrations of at least 1 mg/L to survive in the muddy bottom of the Bay, where oxygen levels are naturally low.
Dissolved oxygen requirements for bottom-dwelling fish, crabs, and oysters are 3 mg/L or higher.
Migratory fish that are spawning, along with their eggs and larvae, require up to 6 mg/L throughout these delicate life stages.
More oxygen can be held in water the colder it gets. The amount of oxygen that may dissolve in the water decreases as it gets warmer. Salinity plays a significant role in determining the volume of oxygen that a body of water can contain, with fresh water having a higher capacity.
When there are excessive amounts of bacteria or algae in the water, oxygen levels may also be diminished. Once the algae have completed their life cycle and have passed away, bacteria eat them. The bacteria also ingest the oxygen dissolved in the water during this process of decomposition. This can result in lower physiologically accessible oxygen levels, which, in some situations, can cause fish deaths and the demise of other aquatic species.

how does gene flow affect genotype and phenotype of a population?
Answer:
Gene flow is the movement of alleles and genes between populations, which can affect the genotype and phenotype of a population. Gene flow can occur through migration, which is the movement of individuals between populations, or through introgression, which is the movement of alleles from one population to another.
Gene flow can have a significant effect on a population's genotype and phenotype by introducing new alleles into the population, resulting in changes to the gene pool. For example, when new alleles are introduced, the frequencies of alleles in the population may change and new genetic variants may become more or less common. This can lead to changes in the population's phenotype, as the new alleles may be expressed differently than the existing alleles, leading to changes in the physical characteristics of the population. Additionally, gene flow can lead to a decrease in genetic diversity, as alleles may become fixed or lost over time.
