Answer:
An astronaut's footprint can last a million years on the surface of the moon.
Explanation:
It may have been decades since we last set foot on the moon, but its surface is still marked with the historic footprints of the 12 astronauts who stomped across it. That's because the moon has no atmosphere.
The correct answer is option B. According to Newton’s third law of motion, the balloon is pushed forward as the air is forced out.
Newton's third law of motion states that to every action there is an equal and opposite reaction. The same law will apply on the balloon. As the air is forced out of the balloon it will exert an opposite force on the balloon which will cause the balloon to be pushed forward. If the air would not have caused an opposite force on the balloon causing it to be pushed forward it would have remained static. But, reaction of the outgoing air pressure made the balloon to move forward.

Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
- a video that shows a large river that has penguin populations on both sides
- a video that shows penguin species that have different mating dances
- a video that shows a penguin that is laying eggs
- a video that shows penguins in a tidal pool and an open ocean
Answer:
a video that shows penguin species that have different mating dances
<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>
<em><u /></em>
<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>
<em><u /></em>
<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>
<em><u /></em>
<em><u>Thus, the selected option is correct.</u></em>
