Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.
This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.
The human activities that could have endangered botana curus is:
Pollution: It lead to slow down the rate of growth of the plant.
Overexploitation: The over use of plant for its medicinal purpose.
Habitat: The natural habitat of the plant has been changed due to various human activities.
A downside to this mutant corn wohld be that it would give rise to a presticide-immune strain of the certain insect.
All the non-immune bugs would die, leaving the few immune ones to reproduce. That would result in a overpopulation of immune super-bug that would still be able to go ham on the large, GMO corn, like nothing happened, and still go on to affect native plant populations. That can become a huge problem.
Hope that helped!
The right answer is <span>A) semi-permeable membrane
<span>A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).
</span>The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).</span>
