A control group is an essential part of an
experiment because it allows you to eliminate and isolate these variables.
Answer:
Chemists use beakers, flasks, burets and pipets to measure the volume of liquids.
Explanation:
Latent heat released during condensation offsets some of the cooling of a rising air parcel, causing the moist adiabatic lapse rate to have a smaller value.
Answer:
Complex media.
Explanation:
In a defined medium the exact composition of each component is known and it contains pure ingredients. In a complex medium, the exact composition of each component is unknown and it often contains extracts of animal or plant tissues (whose exact composition is unknown). In this case, media X contains beef extract, which is an undefined ingredient so it is a complex medium.
