Food provides energy to animal cells, whereas sunshine provides energy to plant cells. Chemicalenergy, which is the energy held in the bonds that connect the atoms of every molecule, is used by all cells. Cells must be able to release the chemical energy in the connections in order to continue to function.
The smallest unit in biology that can sustain life on its own and makes up all living things as well as the body's tissues.
After using a very early microscope to examine a piece of cork, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber."
It is also claimed that he believed the rectangular spaces resembled some monasticcells.
Animal cells get their energy from food, but plant cells get their energy from sunlight. All cells employ chemicalenergy, which is the energy stored in the bonds that bind the atoms of every molecule.
To keep working, cells need to be able to discharge the chemical energy stored in their connections.
Thus, this way, plants and animal cells obtain their energy.

Plant cells obtain their energy by making their own food through the process of photosynthesis. Photosynthesis is a process by which carbon dioxide , water and light energy are utilized by plants to make energy-rich carbohydrates such as glucose. Plants store up the glucose as starch in their tissues. When plant cells needs energy, they simply take glucose molecules from their store of starch and use it in cellular respiration to produce ATP, the form of energy that the cell uses to function.
Animals on the other hand do not make their own food but ingest ready made food and break it down into its simplest units through the process of digestion. Complex carbohydrates are broken down to glucose units. Glucose is directly taken in by the animal cells where it is used in cellular respiration to produce ATP ,which fuels the cell activities.
Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.
B. the building of dams.
C. a slow recharge rate.
D. infiltration by acidic water.
Answer: Option A) sinkhole formation.
Explanation:
A sinkhole refers to any dug-out or depressed area of land where human
or animal waste (excreta) are deposited.
Now, since these wastes contains water and are biodegradable by microorganisms, the fecal matter could be infected and in turns infect groundwater.
The contaminated-groundwater poses danger due to disease-causing organisms like
- vibrio cholerae, causing cholera
- Salmonella typhi, causing typhoid outbreak present, and also reduces volume of suitable drinking water in the community
Thus, the answer is sinkhole formation
