The head of a phospholipid interacts with water because it is

Biology

Delvig [45]3 years ago

Hydrophilic

A phospholipid is comprised of a phosphate hydrophilic head, which means that it is "water-loving," and a fatty acid hydrophobic tail, which is "water-hating." The head and the tail are joined together by a glycerol molecule. 

The phosphate head is attracted to water because it is charged (i.e. negatively). Water is a polar molecule, which means that there is an uneven distribution of charges within its molecular structure with the oxygen side being "more negative" than the rest of the atom (which is "more positive" near the hydrogen). Thus, the negatively-charged nature of the phosphate head and the parts of the water molecule which are positively charged enable the two to form an "attraction" towards one another. 

On the other hand, the hydrophobic tail is nonpolar, which means that it does not have a "more positive" or "more negative" side or part in its molecular structure. These differences in structure with water make the hydrophobic tail unattracted to water molecules and more attracted to other uncharged, nonpolar molecules (such as fats and oils).

All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.

The false spider mite, Brevipalpus phoenicis, has only two chromosomes. Which of the following pieces of evidence would allow yo
Reptile [31]

Answer:

The correct answer is - a. If these two mite chromosomes have different genes at different loci.

Explanation:

If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.
