Q11. The answer is C. organism.
Atoms join in molecules, molecules form organelles. Organelles are parts of the cells which combine to form tissues, tissues make organ systems, and finally all of those combine to form organism.

Q12. The answer is B. nucleus.
Inside the cells, genetic information is organised inside the nucleus. It is known as the brain because it is responsible for most of the cell functions. Similarly to the human brain, which sends information to the other parts of an organism, the nucleus sends information and instructions to the other parts of the cell.

Q13. The answer is C. lysosomes.
Lysosomes are cell organelles which contain hydrolytic enzymes. These enzymes are capable of breaking down biomolecules, such as proteins, lipids, carbohydrates, nucleic acid.

Q14. The answer is A. endoplasmic reticulum.
Reticulum is a latin word meaning network. This means that endoplasmatic reticulum is a network (reticulum) inside the cell, in the cytoplasm (endoplasmatic).

Answer from: Quest

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
