It has been said that life could develop on Earth only because Earth is just the right distance from the sun. Any closer, and it
blondinia [14]

Answer:

The correct answer will be- the planets and moon also exhibit hydrothermal vents, volcanoes and rocks.

Explanation:

Scientists have always tried to understand and explain the origin of life on Earth and predicted that life on earth originated as a result of the conditions created by the distance of the Earth from the Sun.

Later discoveries found that life exists even in the harsh conditions on Earth-like hydrothermal vents and inside sub-surface of the rocks. This shows that life can exist in extreme conditions.

Since the planets other than Earth posses such hydrothermal vents, rocks and volcanoes, therefore scientists predict that life could be found on other planets.

IgorLugansk [536]

Isolation means that organisms of the same species are separated, and happens when there is something between the organisms that they can't cross.

What is an outcome variable? Give an example. (plz i need this)
daser333 [38]

Answer: An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

Explanation: Example: What is a good outcome variable for deciding whether cancer treatment in a country has been improving?

A first thought might be "number of deaths in the country from cancer in one year." But number of deaths might increase simply because the population is increasing. Or it might go down if cancer incidence is decreasing.  "Percent of the population that dies of cancer in one year" would take care of the first problem, but not the second.

This example makes the point that a rate is often a better measure than a count.
