Marrrta [24]3 years ago

Answer:

False.

Explanation:

Cell membrane is made of the lipids and proteins with the attached moieties of carbohydrates. The plasma membrane is the selectively permeable membrane that allows the diffusion of some selected particles only.

The transport along the cell membrane depends on the size and the hydrophobicity of the molecule. The size of oxygen is although higher than magnesium but to its highly hydrophobic nature it can easily pass through the plasma membrane as compared with the magnesium. The oxygen diffuses out faster than magnesium.

Thus, the answer is false.

Lana71 [14]

Answer:

The correct answer is -

Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats

Explanation:

It is given that long hair is a dominant represented by H, over the short hair represented by h. In the cross of a heterozygous cat for long hair with a cat with short hair, would produce H, h and h, h gametes respectively.

Cross: Hh × hh

    H    h

h    Hh   hh

h   Hh   hh

In this Punnett, there are two heterozygous long hair offspring produced and two short-hair cats.

So, Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats
