Answer:
a. The corn borer must have or generate (by mutation) heritable variation in resistance to the toxic protein.
b. The resistant corn borers must survive better or reproduce more than nonresistant corn borers.
Explanation:
When there is a change in the surroundings of organisms, some genetic variations become beneficial to the organisms. Natural selection favors the organisms having these genetic variations.
The development of resistance in the corn borer population requires the presence of the gene for the resistance in the population. If there is no gene already present in the population, there should be a mutation to give rise to such gene/s. The corn borers having this gene should be able to survive better in the presence of the toxic protein and should leave more progeny in order to increase the frequency of the gene in the population over the generations.
Answer:
Hypernatremia
Hypernatremia is
a condition that infers too much salt and less water in the body, which could
result to dehydration where the person is thirsty for plain water after eating
a salty fish. There are sensors in the body that could detect saltiness of the
blood and this sends signals to the brain that the body needs water to dilute
the salt and balance the fluids in the cells. Therefore, making the person feel thirsty for water.
RNA has a ribose sugar instead of deoxyribose sugar like DNA. RNA neucleiotides have a uracil base instead of thymine.
Answer:
What Is Electromagnetic Energy? Electromagnetic energy is a form of energy that can be reflected or emitted from objects through electrical or magnetic waves traveling through space. Electromagnetic energy comes in many examples including gamma rays, X-rays, ultraviolet radiation, visible light, microwaves, radio waves and infrared radiation.
Explanation:
The energy-absorbing molecules for photosynthesis are located in the Thylakoids.
So your answer is A : Thylakoids.
