Answer:
There are two types of errors: random and systematic. Random error occurs due to chance. ... Random error may be caused by slight fluctuations in an instrument, the environment, or the way a measurement is read, that do not cause the same error every time. In order to address random error, scientists utilized replication.

Answer:
Depolarized graded potential.
Explanation:
A depolarizing graded potential is a local change in the membrane potential that makes a small increase in the potential. The membrane potential is less negative because the graded potential caused the entrance of Ca²⁺ or Na⁺ ions to the inside of the cell decreasing the negative voltage in the inside of the cell.
According to climate change scientists, the burning of fossil fuels (coal, oil, and the like) results in the releasing of carbon dioxide atoms into the atmosphere, which can cloud the atmosphere, obscuring sunlight, as well as deplete the ozone layer, resulting in an increase in global temperature. This change could potentially cause some cooler temperature-loving species to either migrate in search of cooler locations or possibly die out if they are unable to move (biosphere). It could also cause water levels in some areas to decrease due to evaporation, or increase due to the releasing of water into the oceans resulting from the melting of our polar ice caps (hydrosphere).

The correct answer is - B) more; in total.
The urban areas use much more energy than the rural areas, by far. The reasons for that are numerous, with the two biggest being the number of people and the industry.
The number of people living in urban areas is higher than the number of people living in rural areas. Also, the people in the urban areas use much more energy because they rely on much more technology, technology that uses energy in order to work.
Most of the industry is also located in and around the urban places. The industry is a huge consumer of energy, thus increasing the usage of energy further more.
Both cells share one similar structure which is Ribosomes.
