A - The alveoli have a membrane that is only one cell thick to allow for a short diffusion time to capillaries.
Answer:
The higher up an object is the greater its gravitational potential energy. This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height
Explanation:
Answer:Aneuploidy: Extra or missing chromosomes. Changes in a cell's genetic material are called mutations. In one form of mutation, cells may end up with an extra or missing chromosome.
Explanation:
Gravitational potential energy is the energy an object has due to its position above Earth, energy due to its height. ... The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
