The symptoms that shelly is experiencing result from the interactions between streptococus pyogenes (a prokaryote) and the cells
Arlecino [84]

Explanation:

While only eukaryotes contain nuclei, rough Endoplasmic reticulum, the golgi complex and mitochondria. Prokaryotes, are unique ad contain a characteristic capsule, while both may have plasma membranes, ribosomes, flagella and a cytoplasm.

Explanation:

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes.

Their structural components (i.e. their makeup) determine their function (what they do). Arranged in a phospholipid bilayer it is a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

These may increase metabolic reaction efficiency and separate proteins and molecules that may harm the cell by parceling them into membrane-bound organelles.

What is the difference between DNA, chromatin, and Chromosomes?
Serhud [2]
Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.

A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.

Under a microscope, chromatids look like little dots and chromosomes are lines.
