Answer:
The cell structures which can be found in every cell are
DNA
Cytoplasm
The Cell Membrane
Ribosomes
Explanation:
The cell structures which are common to every cell whether prokaryotic or eukaryotic are
Deoxyribonucleic acid (DNA): DNA can be referred as the basic hereditary material for all organisms. In prokaryotes, DNA is not membrane bound whereas in eukaryotes the nucleus is membrane bound.
The Cell Membrane: The cell membrane comprises of phospholipid bi layers and other proteins. Cell membrane seperates the cell from the outer environment. It also acts as a barrier for imorting and exporting of materials inside and outside of cell.
Ribosomes: Ribosomes can easily be described as the protein synthesis factory.
Cytoplasm: The fluid material present inside the cell membrane which comprises of all the organelles.
IT is forced into your lungs by the contraction of your diaphragm because the hair you breath is from your lungs and it passes through the diaphragm which causes the contraction
Answer:
D. chemical digestion
Explanation:
In chemical digestion, large food molecules are broken down into smaller particles thanks to the action of enzymes present in the digestive juice, undergoing changes in their chemical composition.
Chemical digestion is a process that occurs with the action of enzymes. It starts in the mouth with the action of the enzyme amylase, which is present in saliva and digesting starch. In the stomach, there is the action of gastric juice, consisting of hydrochloric acid and the enzyme pepsin, which acts on protein digestion. In the small intestine, the food undergoes the action of substances produced by the pancreas (alkaline substance containing trypsin and chymotrypsin, enzymes that act on proteins) and by the liver (bile, which contains salts that act on the digestion of fat, is produced by liver but is stored and concentrated in the gallbladder).
Pathogenic microbes like shigella Flexner, which causes bacillary dysentery in healthy people, are called gram-negative bacteria or<u> gram-negative intracellular bacterial pathogens.</u>
The bacteria of the genus are known as the key representatives of bacillary dysentery.
First of all, this genus funds host cells and then spreads the infection by invading the targets cells,
After that, the cells of the rectal epithelium become inflamed and swollen.
In order to spread the disease through the body, an infective dose containing 10 - 100 organisms is enough for this purpose.
The disease spread by Shigella pathogens is called Shigellosis.
