The variation in beak type enables the different individuals in a population to feed on different food sources.
The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.
Answer:
Cone cells help detect colors.
Explanation:
Light travels into the eye to the retina located on the back of the eye. The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.
RNA and ribosomal proteins <span>are both made in the nucleus and move into the cytoplasm.</span>
The answer is <span>microorganisms have rapid cell cycle.
Microorganisms are much simpler and much smaller organisms than humans. Because of their size and complexity, they reproduce in extremely rapid pace. For example, E. coli population is able to double each 20 minutes. This is, of course, not the case with humans.
For the mutation to become established, there must pass a few generations. So, if a useful mutation establishes in E. coli cell, in 20 minutes it will be present in the next generation, in 40 minutes it will be present in the generation after that, and so on. In the humans, years (not minutes) are necessary for the mutation to be passed down to the first generation. It needs less time to establish a mutation in E. coli than in humans.</span>
