Coat color in rabbits is under the control of a single gene with

Mashcka [7]

Answer: a) Cch x Ccch

b) Ccch x Cc

c) Cch x cchch

d) cchc x chc

Explanation:

Data:

Coat color in rabbits is under the control of a single gene with

four alleles: C (full gray color); cch (chinchilla, light gray); ch

(Himalayan, white with black extremities); and c (albino, absence

of pigmentation).

The dominance hierarchy is represented as: C >cch > ch > c.

Possible genotypes:

For full gray color: CC (Gray), Ccch (Gray-2), Cch (Gray-1), Cc (Gray-3). The allele "C" dominates over the other three alleles, so in every combination where "C" is present, the animal will be fully grayed.

For light gray color/Chinchilla: cchcch (Chinchilla), cchch (Chinchilla-1), cchc (Chinchilla-2). The allele "cch" dominates over "ch" and "c", but not over "C". So if the allele "C" is combined with "cch", the animal will be fully grayed, but in any other combination with "cch", the animal will be light grayed.

For white with black extremities/Himalayan: chch (Hymalayan), chc (Hymalayan-1). The allele "ch" that determines the Himalayan color is only dominant over the allele "c". But in combination with any other allele, "ch" behaves as a recessive one.

For albino: cc. In the presence of any of the other alleles, the allele "c" always behaves as a recessive one. The only possibility of getting an albino animal is if "c" combines with another "c".

A murder occurred in a house. However, investigators search a suspect’s car. What are they searching?

Inga [223]

Answer:A secondary crime scene

Explanation:

The house where the murder occur is the primary crime scene. While the investigator are searching the suspect's car is because it could be the secondary crime scene. In a case where the suspect may have transported the victim to a dumping site, the car is therefore a secondary crime scene because there could be trace evidence in the car that is related to the murder at the primary crime scene. Evidence such as blood stains, victim wallet and others

N-linked glycans are attached to proteins through N-acetylglucosamine or N-acetyl galactosamine to the amide side chain of _____

taurus [48]

Answer:

Asparagine

Explanation:

Glycans are structures made up of chains of simple sugar molecules joined together by chemical bonds. N-linked glycosylation, is the attachment of an oligosaccharide, sometimes referred to as glycan, to the amide nitrogen the amino acid asparagine (Asn) residue of a protein, in a process called N-glycosylation. This linkage is most of the time important for the structure and function of the the protein they are linked to.

How do body systems work together to maintain homeostasis

Novosadov [1.4K]

Answer: By Hormonal action and Nervous coordination

Explanation:

Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.

Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.

For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.

Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc

So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
