zalisa [80]

Answer:

The correct answer is option B. "Raoul's practice is massed; Scarlett's is distributed".

Explanation:

A massed practice condition is defined as a task that its performed by an individual without taking a significant amount of rest. Since Raoul is only taking 5 seconds of rest between trials, his practice is massed. On the other hand, distributed practice conditions involve resting for longer periods of time. Scarlett is resting 40 seconds between trials, which represents a longer period of time that the trial itself (30 seconds), therefore her practice is distributed.

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.
