They are sandwiched between two layers of heads. Recall that the heads are hydrophilic therefore they will always be on the outside and the tails are hydrophobi therefore they willl always be away from water, there fore sandwiched. I'm a bio major, hope I helped :)
Answer:
The water is likely to be dirty or not clear enough. I mean, if you through a key into the body of water, you can't see the key at the bottom of the water body because of impurities which make the water look dirty or not visible or transparent enough.

i guess there should be some options for this question ...
Answer:
2/3
Explanation:
This question involves a single gene coding for the possession or not of Cystic Fibrosis (CF). Since, the disorder is inherited as a recessive pattern, it means the C allele (no CF) is dominant over c allele (CF). This means that only an individual with (cc) genotype can be affected.
However, if a cross between two unaffected parents produced a child with CF, it means both parents are heterozygous or carriers of the trait i.e. Cc genotype. Thus, using a punnet square, a cross between them will give rise to four possible offsprings with CC, Cc, Cc and cc genotypes.
Two children were given birth to, with one having the disorder (cc) and one not having. The CC, Cc, and Cc genotypes will not be affected but Cc will be a carrier. Therefore, the probability of having the unaffected children be a carrier is 2 out of the normal 3 children i.e. 2/3.
