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.
Answer:
Question 1 answer
Plate tectonic began in 1915 when Alfred Wegener proposed his theory which was continental drift. Usually scientists use waves to study the difference of the layers of earth. They use seismic waves. seismic waves are generated by earthquakes or nuclear-test explosions.
Those 3 pieces would be the fit of the continents, paleoclimate indicators, and geologic features. The rock formations of eastern North America, Northwestern Africa and Western Europe were found later to have a common origin. They were found to overlap.
Question 2 answer

I dont know the other ones sorry
Answer:
offsprings have identical genes. It's called asexual reproduction.
Limestone is the correct answer
Answer:
Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.
Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.
Explanation:
Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.
