Microscope Notes

Answer:

The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power.

The amount of light transmitted to your eye is greatest at the low power. When you switch to a higher power, light (and therefore resolving power, or the ability to distinguish two nearby objects as separate) is reduced. Compensate with the light control (sometimes called the iris diaphragm

5. Which of the following statements best describes the response of finches to drought on the Galapagos Islands?
O A During drought, individual finches saw that large, hard seeds were the only available food. To crack these harder seeds, individual finches grew their beaks
larger, resulting in an increased average beak depth
OB During drought, finches struggled to open harder seeds All the scraping and pecking wore down their beaks, resulting in a reduced average beak depth
OC. During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-
beaked finches died, resulting in an increased average beak depth in the population
O D. During drought, finches with smaller beaks (and smaller bodies) had an advantage. With reduced food supplies, larger finches (with larger beaks) were
more likely to starve. The result was a decrease in average beak depth

How large beak finches survive drough condition?

During drought, finches with larger beaks survive because they were able to crack the hard seeds that were available in the drought situation while on the other hand, the smaller beaked finches died due to unavailability of food which result in an increased average beak length in the population.

So we can conclude that option A is the right answer.

Answer:

d. consumers, heterotrophs

Explanation:

Answer:

d. consumers, heterotrophs

Explanation:

Humans cannot be producers since we do not make photosynthesis (our own energy/food), we need to consume food in order to have energy. Therefore, we can't be autotrophs. We are also not decomposers because we don't eat dead animals like for example a vulture.
