Answer AND Explanation:
A variety of organic and inorganic compounds serve very important roles in living things. The various organic compounds constitute the structures of the body and regulate the chemical processes going on inside it.
Carbohydrates are essential for life since they are oxidised during respiration to release energy. Glucose is the most common respiratory substrate. They are also building blocks of polysaccharides such as starch and cellulose in plants and glycogen in animals.
Lipids are important because they can be oxidized during respiration to release energy. They provide twice the amount of energy for the same weight of carbohydrates. They also act as insulators, source of metabolic water and are major components of cell membranes.
Proteins are important structural components of the cytoplasm and various supportive tissues in the body, transport substances, make up hormones and are used as a source of energy through respiration.
Answer:
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscope

Gravity causes the raindrop to accelerate to the ground at a rate of 10m/s². However, air friction acts against this gravitational acceleration by reducing the rate of acceleration of the raindrops. The higher the friction surface of the raindrops the lower the terminal velocity.
Gases, too much carbon dioxide being lifted in the air. Factories, waste and waste in water. Hope this helps.
Answer:
C. Diabetics will have ample supplies of insulin that are produced by bacteria.
Explanation:
The technology of recombinant DNA has allowed scientists to introduce the human insulin gene into E.coli bacteria. E. coli are thus turned into "biological factories" that produce large quantities of human insulin, which can be easily purified and used as medicine for diabetics.
There are many more examples of DNA recombinant technology in human medicine, such as the production of recombinant human growth hormone (hGH) also in E. coli that is injected in individuals who don't produce enough hGH naturally, or even the production of vaccines by inserting antigen-coding DNA into a cell, purifying it and later injecting it into individuals to stimulate immunization.
