Why is the phospholipid bilayer arranged the way it is?

Biology
1 answer:
hram777 [196]4 years ago
3 0

Answer:

They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group. The two components are usually joined together by a glycerol molecule. The phosphate groups can be modified with simple organic molecules such as choline, ethanolamine or serine.Explanation:

In radishes, red and white are pure-breeding colors, while hybrids are purple. If a red radish is crossed with a white radish, w
zlopas [31]
The answer is 1 red radish, 2 purple radishes, and 1 white radish

Let R allele be dominant allele over r allele. The genotypes and phenotypes will be as following:
RR - red radish
rr - white radish
Rr - purple radish

Parental generation:       RR      x      rr
F1 generation:             Rr      Rr    Rr     Rr

Since the F1 generation self-pollinates, we have the situation:
F1 generation:             Rr    x    Rr
F2 generation:         RR   Rr    Rr    rr

Punnet square:
                          <u>       Rr     </u>       
                          <u>R      </u><span><u>|   r</u>
             <u>R   </u></span><u>|     RR    |   Rr</u><span>
Rr           <u>r   </u></span><u>|     Rr      </u><span><u>|  rr</u>

So, there will be 1 red radish (RR), 2 purple radishes (Rr), and 1 white radish (rr)</span>
