Answer:
Density (ρ) = 7 gram/cubic centimeter
Explanation:
Density is the mass of an object divided by its volume.
Density often has units of grams per cubic centimeter (g/cm3).
So, the block of iron would have a density of ( 420 g / 60 cm^3 =) 7 gram/cubic centimeter
Glucose is consumed, and carbon dioxide is produced.
C it is made up of specailized cells that form straw-like tubes
Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.
Explanation:
Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.
Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.
I hope that it is correct
