Guinea Pigs can either have black fur (B) or white fur (b) and rough textured coats (R) or smooth textured coats (r).

cricket20 [7]

Answer:

The answers are explained below:

Black rough fur - $\frac{1}{2}=\frac{8}{16}$ .
Black smooth fur - $\frac{1}{2}=\frac{8}{16}$ .
White rough fur - $\frac{0}{16}$ .
white smooth fur - $\frac{0}{16}$

Explanation:

The genotype of homozygous black fur and smooth texture: BBrr.
The gametes produced are : Br
The genotype of white and heterozygous for rough texture: bbRr
The gametes produced are : bR and br.
The cross,

bR br

Br BbRr Bbrr

(B/R) (B/S)

In the brackets (),

B - Black.
R - Rough.
S -Smooth.

The cross can develop two types of offspring, that is,

Black and Rough (BbRr) - 1.
Black and smooth (Bbrr)- 1.

The answers:

Black rough fur - $\frac{1}{2}=\frac{8}{16}$ .
Black smooth fur - $\frac{1}{2}=\frac{8}{16}$ .
White rough fur - $\frac{0}{16}$ .
white smooth fur - $\frac{0}{16}$

What causes the phospholipids to organize themselves the way they do

Anni [7]

All of the liquid molecules in cell membranes amphipathic (or amphiphilic) -that is, they have a hydrophilic ("water loving") or polar end and a hydrophobic ("water fearing") or nonpolar end. The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.

Hope that Helps :)
