Medicines that relieve pain are called B.analgesics.
Analgesics are used to achieve analgesia, which is relief from pain. So, analgesics are painkillers.
Antifungals are used to treat fungal infections,
Antivirals are used to treat viral infections, and
Anticellulars are used against specific types of cells, such as cancer cells.
Given that,
Density of the liquid, d = 3 g/ml
Volume, V = 20 mL
To find,
The mass of the liquid.
Solution,
The density of an object is given by its mass divided by volume such that,
d = m/V
m is mass
m = d×V
Put all the values,
m = 3 g/mL × 20 mL
= 60 grams
Hence, the mass of a liquid is 60 grams.

Photosynthetic organisms require light, in which the sun’s rays can only go so far

The energy flow pyramid goes from decomposers to producers, meaning that if producers are dying out due to lack of nutrients, there must be something wrong with the decomposer population
Bacteria in a unicellular organism that has an archaic structure but is very smart, specifically in antibiotic resistance.
Bacteria have several characteristic or "weapons" to fight antibiotics:
Bacteria has a cell wall which do not allow toxic substances to go in.
Bacteria has transporters which expulse the antibiotic molecules that enter into the cell.
Bacteria has enzymes that break the antibiotic molecules and make them inactive
Bacteria can mutate (change) itself so, and by the way the antibiotic sites, so the molecules cannot fix it. And that is the most problematic.
Bacteria can transmit it resistance mechanism to other bacteria, even if they are not from the same family.
