What is the process of double pump?
seropon [69]

Answer:

Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. ... The second pump delivers oxygen-rich blood to every part of your body. Blood needing more oxygen is sent back to the heart to begin the cycle again.

Which would be an adaptation in a very cold place but not in a rainforest?
dmitriy555 [2]

Answer: The adaptations like paddy feet and fur on the outer body is an adaptation for very cold place but not for the rain forest.

Explanation: If the outer body of the organism is made of fur then it will protect the inside body from cold and will provide warmth.

But if the body will have adaptation like fur in the rain forest then it will make the organism wet so there will be no use of fur on the outer surface of the organism.

The adaptation like camouflage will help the organism in the rainforest so that it can hide themselves from predators in the forest.

Lunar Tides: the moon's gravitational pull on the Earth is strongest at this time, because it is closest, causing especially high and low tides.

Solar Tides: the sun's gravitational pull on the Earth is strongest at this time, causing especially high and low tides (although it's not as powerful as lunar tides).

Spring Tides: named for when the tides "spring" forward during New and Full Moon's, because of how strong/weak the moon's gravitational pull is.

Neap Tides: the tides are especially mediocre at this time, because the sun and moon are at a right angle and pulling in opposite directions.

Spring and Neap Tides occur twice every moon cycle, which lasts 28 days, so every two weeks.
