Assume that a single layer of phospholipids coat the water in a beaker. which part of the phospholipid molecule will face the ai
r? a.the phosphate groups
b.the hydrocarbon tails
c.the phospholipids would dissolve and not form a membrane coat
d.both heads and tails as the molecules are amphipathic and will lie sideways
A phospholipid molecule comprises of a head group (that contains polar phosphate molecule) that is hydrophilic ( water attracting groups due to formation of hydrogen bonding or ionic bonds with water molecules) and two tails of fatty acid ( which are hydrophobic that is water repelling groups).
In this question, a single layer of phospholipid coats the water in a beaker. This means that head group of this layer is in contact of water ( present in the beaker) and the two fatty acid tails of hydrocarbon ( that are water repelling) are facing air.
The part of the phospholipid molecule that will face the water, as it is labelled to be hydrophilic would be the polar phosphate group. The correct response would be A.
Notice that many amino acids are represented in the table by more than one codon. For instance, there are six different ways to "write" leucine in the language of mRNA (see if you can find all six).An important point about the genetic code is that it's universal. That is, with minor exceptions, virtually all species (from bacteria to you!) use the genetic code shown above for protein synthesis.
Explanation: it has one recessive allele so whether it reproduces with another heterozygous or h mzygous the offspring could end up with that recessive allele
if the question was a recessive phenotype they would need to find another heterozygous individual to put together the 2 recessive alleles to show the recessive trait
