From the outside, a whale's flippers appear to be flat, solid objects. However, when scientists observed the
bones within whale flippers they found bones like the
ones shown in the diagram.
Observing the bones made scientists ask more
questions about whale flippers. Scientists then used
the theory of evolution to understand how whales are
related to land mammals. They surmised that over
millions of years, the land mammals slowly adapted to
living near the sea and then living in the sea, where
solid flippers are more useful than fingers.
What part of the scientific cycle was used to
understand why whales have finger bones?

answer; i believe the correct answer to the above question is ( friction)

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
