1. Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.
2. The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you.
Answer: Some of the intestinal symptoms elicited by pathogens such as salmonella, shigella, and Escherichia are due to the presence of lipopolysaccharides.
Pathogen associated molecular patterns binds to toll like receptors to elicit a response include lipopolysaccharide or LPS. The bacterial component interaction with the host involves LPS and other components of cell wall causing a septic shock. The triggering of any event of septic shock is directly related to the release of LPS or other bacterial toxins into circulation. Pathogen associated molecular patterns are the molecules which are made by the pathogen and needed for their survival or pathogenic character includes LPS.
Answer:
Restriction enzymes
Explanation:
Restriction enzymes are also called 'molecular scissors' as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.
Answer: No. You would not withdraw CSF if the needle is in the epidural space.
Explanation: There are 3 spaces that cover the spinal cord, which are epidural, subdural and subarachnoid spaces. The epidural space is the outer most space while the subarachnoid space is the inner most space. CSF flows from the brain where it is produced to the spinal cord. In the spinal cord it flows only in the subarachnoid space. Thus you would not be able to withdraw CSF if the needle is in the epidural space.
Plasma membrane allows some material to pass through it while on the same time it blocks other material from entering through it.
