Answer:
The correct answer is A. Fossil fuels are cheaper than alternative forms of energy
Explanation:
Fossil fuels are made from organic matter of dead animals and mainly plants who were buried in the soil over hundred and thousand of years. We use fossil fuels because they are the best source to provide energy in the current time.
Fossil fuels are easily available and are present in very large amount which is the main reason for it to be cheaper. Fossil fuels like coal, petroleum or natural gas are more cheaper and efficient than alternative forms of energy like solar or wind energy.
But in future these fossil fuel will not be there and alternative forms of energy will become the primary and cheaper source of fuel.
Answer: Nucleiod, Ribosomes, flagella, fimbriae, plasma membrane
Explanation: A typical bacteria cell possess these structures mentioned above. nucleiod is a chromosome , a nucleic acid which can be DNA or RNA, It is the genetic material of cell which every bacteria cell must have. Flagella ensures swimming movement of all bacterial cell. Ribosome of bacteria cells ensures protein synthesis. Since all bacteria cells meet, plasma membrane is permeability barrier, location of enzyme and transports solutes. Fimbriae enables bacterial cells attachment to surfaces
Cellular respiration<span> is </span>the process<span> of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the </span>cell<span>. </span>The process occur<span>s in two phases: glycolysis, the breakdown of glucose to pyruvic acid. </span>
Process of photosynthesis makes glucose. Excess glucose is stored as starch, or made into cellulose in cell walls.
