Some peeled pieces of apple were placed in distilled water and some in very salty water. The cells in the apple pieces will

Answers

I think that they will gain water in the distilled water and lose water in salty water. I think water will be lost because salt is used as an drying agent, it is why when it snow they will put salt on ice to keep the ice from being slippery because it dries things up. Distill just means to purify something.

. In fruit flies, normal wings are dominant and short wings are recessive. Construct a Punnett square wherein both parents are heterozygous for normal wings. Which of the following is the correct genotypic ratio for the F1 generation of this cross?25% of the offspring are homozygous for normal wings. 50% of the offspring are heterozygous for normal wings. 25% of the offspring are homozygous recessive for short wings.
75% of the offspring have normal wings, and 25% of the offspring have short wings.
50% of the offspring are heterozygous for normal wings. 50% of the offspring are homozygous recessive for short wings.
75% of the offspring are heterozygous for normal wings. 25% of the offspring are homozygous recessive for short wings.

Answers

Answer:

25% of the offspring are homozygous for normal wings. 50% of the offspring are heterozygous for normal wings. 25% of the offspring are homozygous recessive for short wings.

Explanation:

Let dominant allele be A and recessive allele be a

Parent 1: heterozygous normal wings = Aa

Parent 2: heterozygous normal wings = Aa

Parent 1 X Parent 2 :

A a

A AA Aa

a Aa aa

Genotype of progeny will be as follows:

1/4 or 25% = AA = homozygous dominant for normal wings

1/2 or 50% = Aa = heterozygous normal wings

1/4 or 25% = aa = homozygous recessive for short wings

Normal wings = WW
Short wings = ww

The Parents = Ww x Ww

A. 25% are homozygous dominate, 50% are heterozygous, 25% are homozygous recessive.

Which of these proteins in mammals show only primary and secondary structures?Oxytocin
Keratin
Hemoglobin

Answers

The correct answer is keratin. Proteins like keratin are made up of multiple peptide chains (polypeptide); these are group of amino acids joined by peptide bonds. The sequence of amino acids in a protein is the primary structure while the specific shape in which it is folded (alpha or beta) is called the secondary structure.
