From the Punnett square, the genotype of the offspring produced is:

1 h0moxygous Black,BB; 2 two heterozygous black = Bb, Bb; and 1 h0moxygous white, bb; guinea pigs

The phenotype of the offspring will be:

Three Black fur guinea pigs and one White fur guinea pig.

<h3>What are phenotypes and genotypes?</h3>

Genotypes are the sum total of all the genes that code for a particular trait present in an organism.

The genotype is the sum of all the alleles for a gene in an organism.

Phenotype refers to the physical features of an organism as a result of the genotype of that organism.

Considering the cross between two heterozygous black guinea pigs:

black fur is dominant over white fur in guinea pigs

Let the allele for black fur be B and the allele for white fur be b

The genotype of the heterozygous black guinea pigs = Bb

The cross between the parents is as follows:

Bb * Bb

Using a Punnett square, the genotype of the offspring produced will be:

BB, Bb, Bb, bb

The phenotype of the offspring will be in the ratio 3 Blacks to 1 White guinea pig

How does an r group determine if an amino acid is acidic basic or nonpolar?

Alinara [238K]

<span>R group (or side chain) is an organic component of amino acids that is unique to each amino acid. </span> <span>Three of the amino acids have basic side chains at neutral pH: arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base and their pKa's are high enough that they tend to bind protons, (positive charge). Aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu) are acidic amino acids because their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, (negatively charged). The non-polar amino acids contain uncharged functional groups<span> at physiological pH and are incapable of participating in hydrogen bonding. </span></span>

Answer the following questions:

Naddik [55]

Answer:

1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .

2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).

4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.

5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body
