Answer:
carbon dioxide and oxygen
Explanation:
Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.
The statement above is TRUE.
RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar phosphate backbone of RNA is broken, thus cleaving the RNA molecule.
This reaction is made possible in RNA because the ribose sugar in RNA has hydroxyl group at the two prime position.
Answer:
Isotonic
denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid.
Hypertonic
having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
Hypotonic
having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
Explanation:
Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.
