B, do you have a tutoring option on your account?
The answer is B. Invasive species are successful in novel environments due to lack of a natural predator or competition. Therefore if the non-native share a niche with other fish in the lake ecosysem, there will definitely be competition for resources. This could lead to competitive exclusion of one species or resource partitioning between the species. Consequently, the non-native fish species will not invade the new environment unchecked.
The answer is C) Dripstone produced by a buildup of minerals precipitated fro. groundwater.
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: glycogen is insoluble in water
Explanation:
Glycogen is a better storage of glucose because Glycogen is insoluble in water thus, because of the glycosidic linkages. Storing glucose as glycogen will not upset the osmotic pressure rather than glucose which is soluble in water and if it is stored as glucose it will disturb the osmotic pressure making the solution hypertonic that will cause the cell to lyse.
The glucose from glycogen is readily mobilized and is therefore a good source of energy when needed rather than free floating glucose
