Despite the relative ease of designing quadrat studies, it is possible to introduce errors into a project. Quadrats that are too large, too small or spaced inappropriately often result in errors. For example, larger species require larger plots. Randomly spaced quadrats that are too small might miss too many individuals, resulting in under-representative estimates of population size.

gravity

explanation:

mass and volume are the answers you are looking for

answer: a. same unit

explanation:

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
