In sickle cell anemia, there is a replacement in the amino acid sequence of hemoglobin of glutamic acid by valine. what is the difference between glutamic acid and valine?

Valine is a hydrophobic amino acid used for biosynthesis of proteins.  It is essential in humans, meaning the body cannot synthesize it and it must be obtained from the diet.

Glutamic is a hydrophilic amino acid used by almost all living beings in the biosynthesis of proteins. It is non-essential in humans and the body can synthesize it.

they absorb it i think

not sure

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
