According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. The use for the water in the world is for household drinking water. The ocean stores about 97 percent of the Earth's water; the remaining three percent is stored in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is stored in the ocean.

If a plant just did photosynthesis then the plant would not have any food and just an abundant amount of ATP. they use cellular respiration to make food they can use to grow
Answer:
The correct answer would be "Can prevent genetic diseases".
Cloning refers to the process of making an identical copy of organism, cell or DNA fragments.
One of the applications of cloning is eradication or prevention of genetic diseases.
It is done by isolating the correct or functional gene and make copies of it in in-vitro conditions.
The gene or DNA fragment is then inserted back into the cell.
With advancement in cloning process and understanding of stem cells, cloning process also favors tissues and organ harvesting which also help in reducing diseases.
Answer:
Explanation:
The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.
These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.
WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:
==> If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.
==>build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.
==> absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.
==> Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.
