Answer:
The gametophyte is green and nutritionally independent in mosses, liverworts, and fern.
Explanation:
The gametophyte is the sexual stage of growth in plants and algae.
During this stage, there is production of reproductive organs which produce sex cells.
During this stage, the gametophyte is independent since it relies fully on itself for food production.
The presence of chlorophyll enables this independence.
The gametophyte produces its own food through photosynthesis.
Explanation:
Fossil fuels are important energy sources for our every day activities.
Formation of fossil fuels
Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.
How are they obtained
First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.
For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.
For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.
How are they used
Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.
Natural gas is used as a domestic fuel for cooking and so also coal.
When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

ANSWER FOR QUESTION 1:
The most common type of E. coli infection that causes illness in people is called E. coli O157, which produces a toxin known as Shiga-toxin. Shiga-toxin producing E. coli is abbreviated as STEC. Symptoms of infection with this germ include watery or bloody diarrhea, fever, abdominal cramps, nausea, and vomiting.
ANSWER FOR QUESTION 2:
Some other germs don’t cause as many illnesses, but when they do, the illnesses are more likely to lead to hospitalization. Those germs include: Anyone can get sick from eating contaminated food. Follow four simple food safety steps —clean, separate, cook, and chill—to lower your chance of food poisoning and to protect yourself and your loved ones.
