AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia

Which of the following does NOT characterize proteins?

8090 [49]

Answer:

The answer is C) They appear to be the molecular carriers of coded hereditary information.

Explanation:

Why NOT C) They appear to be the molecular carriers of coded hereditary information?

This is the job of the nucleic acids. It is composed of nucleotides which are the basic units of DNA and RNA. They carry genetic information about a certain organism.

<h3 /><h3>True of proteins:</h3>

A) They may be denatured or coagulated by heat or acidity.

Denaturation is the destruction of the protein's secondary and/or tertiary structures. The primary structure is not disrupted due to the tough peptide bonds and can only be broken down by acid. For heat denaturation, hydrogen bonds are destroyed, as in cooking of egg whites and medical equipment sterilization.

B) They have both functional and structural roles in the body.

There are many kinds of proteins that have functional and structural roles like hormones (FSH, LH), antibodies (IgA, IgM), enzymes (lipase, amylase), for storage/transport (hemoglobin, ferritin), and locomotion (actin, troponin).

D) Their function depends on their three-dimensional shape.

Just like hemoglobin, it's quaternary structure can carry 4 molecules of iron in one go. Enzymes are shaped accordingly to fit a specific substrate (lock-and-key model)

Controlled nuclear chain reactions ____.

inna [77]

Answer: a. take place in nuclear reactors

Controlled nuclear chain reactions are the reaction in nuclear reactors. The reaction is controlled to make its rate slower. This will make the reaction relatively safer, so the energy produced can be changed into electricity in power plant. When the reaction is not controlled, it could cause explosive like in nuclear bomb.
