Answer:

D

Explanation:

It can't be A as nuclei must be positive.

It can't be B as nuclei must contain at least one proton, and no electrons.

Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.

In peas, tall plants (T) are completely dominant over short plants (t). You cross two heterozygous pea plants Use a Punnett squa
Nikitich [7]

Answers and Explanation:

Find enclosed the Punnet square.

T= dominant allele

t= recessive allele

Tt= heterozygous genotype

TT and tt= homozygous genotype

- The male pea plant's genotype is Tt (heterozygous)

- The female pea plant's genotype is Tt (heterozygous)

- Male gametes: T and t

- Female gametes: T and t

- The expected genotypic ratio of the offpring will be:

TT: Tt: tt ⇒ 1: 2: 1

1/4 of the offpring will be TT genotype (dominant homozygous), 1/2 of the offpring will be Tt (heterozygous) genotype and 1/4 of the offpring will be tt genotype (recessive homozygous).

- The expected phenotypic ratio of the offpring will be:

tall : short ⇒ 3 : 1

3/4 of the offpring will be tall (TT and Tt) and the restant 1/4 will be short (tt).

How is tonicity affected by solutes?
zloy xaker [14]

Unlike osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an effective osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always equilibrate with equal concentrations on both sides of the membrane without net solvent movement.
