Okay, stay with me here...
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
Yeah, you might have to reread that a few times, but DNA isn’t an easy topic. It is very complex. I hope this helps!

The preoperational stage is one of the many stages of a child's development. Piaget states that the most obvious change during the preoperational stage is the increase in a child's use language as a symbol or tool for communication. Though they can use language as symbols, they are still not able to form logic or transform ideas into understandable information.

➷ If the person is heterozygous, the alleles of the blue eyed person would also be Bb. The chance of brown eyed offspring is 3/4 and the chance of blue eyed offspring is 1/4. There can't actually be a heterozygous recessive allele. This is because for the recessive trait to come through there would need to be two alleles. It would be a homozygous blue eyed recessive trait.

<span>Phospholipids are the type of lipid that make-up the bilayer
of cell membranes. They have an amphiphilic characteristic which enables them
to form lipid bilayers of cell membranes. Phospholipid molecules are composed
of two hydrophobic fatty acid that serve as “tails” and glycerol molecules that
serve as hydrophilic “heads” of cell membranes. Lecithin was the first
phospholipid identified in 1847. It was found in the egg yolk of chickens by
Theodor Nicolas Gobley, a French chemist and pharmacist. Sterols are a common
type of lipid that is found in eukaryotic cells that provide the membrane
fluidity and mechanical strength. </span>
