Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
There you go sir! Hope I helped
Answer: Natural selection is the driving force to explain the mechanisms of evolution.
Explanation:
◼In a given population Organisms usually produce more offspring than what the environment can support.
◼ VARIATION, is driving force for the manifestation of sustainable inheritable characteristics from parents in a given population.
◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.
◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.
◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.
This is survival of the fittest by natural selection
, this is the second conclusion of Darwin theory.
Answer:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
