Two unlinked loci affect mouse fur color. nn or nn mice are agouti. mice with genotype nn are albino because all pigment production is blocked, regardless of the phenotype at the second locus. at the second locus, the a allele (agouti coat) is dominant to the a allele (black coat). what would be the result of a cross between two agouti mice of genotype nnaa?
The result of a cross between two agouti mice of genotype nnaa are albino offspring because mice with genotype nn are albino (pigment production is blocked by epistasis).
What is epistasis?Epistasis is a genetic phenomenon where the presence of a gene variant alters a phenotype influenced by other genes.
A gene is epistatic when a variant (allele) can alter the expression of another gene in the same signaling pathway.
Epistatic interactions are very common in nature and many traits are influenced by this type of interaction.

What is one possible result of a mutation within a start codon? A stop codon?
The result of a mutation within a start codon is the non-start of the protein translation, whereas a mutation in the stop codon will long the length of the protein.
What are transcription and translation?Transcription refers to the process by which a fragment of DNA is used as a template to create an RNA molecule, usually a messenger RNA.
Subsequently, this mRNA sequence can be used to create a protein by a process called translation.
The triplets of nucleotides (codons) in the mRNA are read by the ribosomes during translation, thereby a mutation in the start codon would produce a nonfunctional mRNA.
Moreover, a mutation in the stop codon will long the length of the resulting protein sequence.

Answer:
Blue crab is an important resource in my region. It is harvested in Chesapeake Bay. People in my region have been eating blue crabs for hundreds of years. Blue crabs are usually harvested in traps called crab pots. Most crabs are harvested commercially, but recreational crabbing is also important. Crab harvesting in Chesapeake Bay is regulated by the states of Maryland and Virginia, and special licenses are required. Limits are placed on the number of crab pots and the sizes of crabs that can be kept. Even though regulations are in place to protect the crabs, their numbers are declining due to deteriorating water quality in Chesapeake Bay. The crabs require additional protection, but too many restrictions could put people out of work because blue crabs are a popular, traditional food in the region, and thousands of people make a living from crab fishing. The natural resources management of the crabs is inadequate because the crabs continue to be harvested in an unsustainable way.

What are 'prokaryotic organisms'? What are some examples?
Explanation:
Prokaryotic organisms are type of cells that are clearly different from eukaryotic cells (human or plant cells), since they lack nucleus and other type of organelles and differ with size. ( some of them have flagella which helps these cells to move)
Example: Any type of bacteria can be considered as a Prokaryotic cell
Prokaryotic organisms are organisms that lack a true nucleus or in other words that have a primitive nucleus. This includes bacteria, E-coli, etc.
What is the difference between prokaryotes and eukaryotes?Eukaryotes are the organisms that have a well developed nucleus. They also have membrane bound cell organelles. These are generally multicellular.
Prokaryotes have a primitive nucleus, and the organelles are also not membrane-bound. These are unicellular.
Prokaryotes are divided into bacteria and archaebacteria. Most of them are small, single-celled and relatively simple. Example cyanobacteria, bacteria, E-coli, etc.
Thus, the organisms like bacteria, which lack a true nucleus are called prokaryotes.

Explanation:
The cerebellum is at the back of the brain, below the cerebrum. It's a lot smaller than the cerebrum. But it's a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together).
Muscle control and body coordination are controlled by the cerebellum.
The cerebellum is a highly specialized region of the brain located at the back of the skull, beneath the cerebrum. It is usually referred to as the "little brain" due to its appearance and position. Although it constitutes only about 10% of the brain's total volume, the cerebellum contains an enormous number of neurons.

Since forces cause a change in motion or state of a body, friction is a force which opposes motion of an object over another.
What is frictional force?Frictional force or friction is the force that opposes the relative motion of one object over another at their surface of contact.
The two types of friction are:
static friction andkinetic frictionRough surfaces experience the greatest friction while smooty surfaces experience the least friction.
Hence, friction can be reduced by lubrication or polishing.
Based on the property of forces and friction:
Force is defined as a push or pull that starts, stops or changes the direction of a moving object.Friction is a force that opposes motion between two surfaces sticking or touching together.A sandy floor has the greatest frictional force among these surface.Friction is a force that opposes motion. It acts in the opposite direction of a moving object. Friction is a force that occurs when surfaces touch each other.
