The correct response is a. Resting membrane potential (RMP). RMP describes the electrical potential difference across a cell membrane when the cell is not active. This difference arises due to the uneven distribution of ions such as Na⁺, K⁺, Cl⁻, and Ca²⁺ across the plasma membrane. It is influenced by the concentration gradients and the permeability of the membrane to these ions. The RMP value can vary by cell type; for example, a neuron's RMP is around -70 mV, whereas in skeletal muscle, it is about -90 mV. A negative value indicates a higher concentration of negative charges inside the cell compared to the outside.

Explanation:
For approximately 250 years, or two and a half centuries, there has been a rapid consumption of fossil fuels to satisfy human demands. These fossil fuels release significant quantities of carbon dioxide when combusted. As a result of burning these resources in factories, power plants, vehicles, and more, carbon is emitted into the atmosphere. Carbon dioxide acts as a greenhouse gas, which leads to the trapping of heat and an increase in global temperatures.
It's projected that nearly 5.5 billion tons of carbon dioxide are emitted annually due to fossil fuel combustion. This vast quantity is overwhelming for plants to convert into oxygen through photosynthesis, causing an imbalance in the carbon cycle. Consequently, more carbon dioxide is produced than can be absorbed, ultimately contributing to a rise in the planet's temperature as the excess carbon dioxide captures additional sunlight.
Water is primarily moved in and out of cells through osmosis. This process significantly helps in sustaining the turgor pressure, which is determined by the osmotic balance between the cell's interior and its comparatively less concentrated surroundings.

Explanation:
The concept of spontaneous generation proposed that life could arise from 'nothing.' This idea remained accepted until it was challenged by Francesco Redi and Luis Pasteur through experiments. Redi conducted an experiment where he placed cooked meat on two plates—one was covered with a glass bowl, while the other was left exposed. The covered plate did not develop maggots, but the open one did, indicating that maggots resulted from eggs laid by flies. Thus, life originates from pre-existing life.
