Ans.

Vestigial organs or structures are those structures that are no longer functional in current organisms, but were functional in their ancestral organisms. Examples of vestigial organs include appendix, hairs, and tailbone in humans.

-Tailbone in humans is a vestigial structure as humans do not have tails. Tailbones are functional in monkeys as they have long tails, which they used for balancing. Hence, 'tailbone in humans' correctly matches with 'balancing in monkeys.'

-Eyeballs in cavefish are vestigial organs as eyeballs are non-functional in cavefish. Cavefishes cannot see as they lost their sights during evolution as it is not necessary since they live in dark caves. Eyeballs are functional in whales as they provide eyesight to them. Hence, 'eyeballs in cavefish' correctly matches with 'sight in whales.'

-Pelvis bones in whales are vestigial structures as there is no role of these bones in whales. Pelvic bones are functional in frogs, as their limbs are attached to the body with the help of pelvic bones. Hence, 'pelvic bones in whales' correctly matches with 'attachment point for limbs in frogs.'

I believe it should match as the following...

sight in whales -----> eyeballs in cavefish

balance in monkeys -----> tailbone in humans

attachment point for limbs in frogs -----> pelvis bone in whales

If the population of Shanghai increases to 30 billion people, how much land would its people need if the population density is 3
nadezda [96]

784109 People per sq. mi land would its people need if the population density is 3,826 people/km2.

<h3>What is population density?</h3>

The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.

The population density equation below can be used to calculate the population density of a piece of land:

        Population Density = Population/ Area

The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.
