Why do human practices depend upon and benefit from water?
Why is water important to our planet?
Answer:
Water us important to out planet because almost every animal and plant needs water to survive.
Explanation:
Water has been the most crucial molecule that supports life on earth. It is a most important solvent that makes up the majority of living organisms and is involved in cellular activities.
What is the importance of water?Water has been defined as the most crucial molecule that supports and benefits the living organism. They are the abiotic factors that all the biotic factors depend on for their growth and development.
All the activities involved with survival have been dependent on water to sustain all the living functions and reactions. It is important for the planet as it is involved in all spheres and biogeochemical cycles. It is the elixir that carries life forward.
Therefore, water is the most important for humans, other organisms, and the planet.

B>breakdown of glucose occurs in many small steps.
C>Low-temperature breakdown of glucose is done by enzymes that catalyze specific reactions.
What is the importance of glucose?Series of reactions that remove energy from glucose by splitting it into two or three carbon molecules (pyruvates) is known as Glycolysis.
Glucose is the main energy source for cellular metabolism. Human beings derive energy from three classes of fuel molecules, namely carbohydrates, lipids, and proteins. The potential chemical energy is transformed into other forms such as thermal or kinetic.
Glucose is absorbed by stomach and small intestines absorb and then released into the bloodstream. Once they reach the bloodstream, then glucose can be used immediately for energy or stored, to be used afterwards. Human bodies require insulin to use or store glucose for energy.

explain the steps that occur when precipitation is forming :)
Answer:
Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice.

how are fungi organized to stay alive?
Fungi are eukaryotes and have a complex cellular organization. As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum and Golgi apparatus
HOPE THIS HELPED <3
Answer/Explanation:
Somewhat like animals, Fungi need oxygen and eat dead organisms in order to survive. A fungus may look like a plant, however it gets energy from living of dead plants and sometimes other fungi. Fungi need a moist area to live with plenty of oxygen making rotted out trees a perfect place to grow.
Fungi are eukaryotes and have a complex cellular organization. As the fellow answerer above said, it has mitochondria and cell membranes that are artistically arranged. Unlike plants, they do not have chloroplasts nor chlorophyll.
