Answer:

The correct answers would be natural selection and high genetic variation in the species.

Natural selection refers to the natural phenomenon by which organisms which are better adapted or have survival traits tend to survive and reproduce more in the environment.

It leads to an increase in the frequency of the trait in a population.

Genetic variation refers to the sum total of all the genetic characteristics present in a population. Higher genetic diversity higher are the chances of a population to survive.  

Similarly, different sizes of the beaks are the result of high genetic diversity out of which large size beak was favored by natural selection.  

Ultimately, the large beak size trait spreads through the population.

The bees wing are moving very fast the best wings are much smaller than it body ?
marishachu [46]

Explanation:

It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.

Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.
