The answer is <span>b. transport proteins.
</span>
Facilitated diffusion is the process of passive transport, which means without using of energy, of ions and molecules across a cell membrane. Although, this process does not require energy such as active transport, transport proteins are required. The role of transport proteins in facilitated diffusion is to provide a hydrophilic route within hydrophobic lipids of the membrane, and that way facilitate ions and molecules to cross the membrane.

An imaginary species of bears, fur color can be purple or gold. Gold is the dominant trait. How would the bear look if the gene
BARSIC [14]

Answer:

<h2>Gold</h2>

Assume Gold trait =P ,

Purple= p,

Given:

Gold (P) is dominant over purple(p), so P is dominant over p.

If the bear is homozygous pp ( recessive)  then bear will look purple,

If the bear is heterozygous Pp, then bear will look gold,

If the bear is homozygous DD( dominant), then the bear will look GOLD,

In holstein cattle, the allele for black hair color (b) is dominant over the allele for red hair color (b), and the allele for p
ELEN [110]

I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.

We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.

It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
