Answer:

Rapid acceleration requires a cheetah to have high oxygen intake adaptations including enlarged nostrils and extensive, air-filled sinuses. While running, a cheetah's specially adapted respiratory system allows it to go from a normal rate of 60 breaths per minute to 150 breaths per minute. The spine is highly flexible — another adaptation for an animal that makes sudden, long, and rapid strides.

The basic idea is that black stripes would absorb heat in the morning and warm up zebras, whereas white stripes reflect light more and could thus help cool zebras as they graze for hours in the blazing sun. Zebras camouflage helps  to confuse big predators, and gives an identity signal to other zebras and a kind of wearable air conditioner. Now most scientists agree that the function of a zebra's stripes is to ward off biting flies that can carry deadly diseases.

Which factor when doubled would produce the greatest change in the centripetal force?
yaroslaw [1]
Let us consider the centripetal force equation,  
centripetal force F = mv² / r  
 f= force
 v= velocity
 m= mass
 r= radius.
 
 in all the factors only velocity has the power of 2. so when you double the velocity then it will become square of that. 
 if v= 2v , F = m4v² / r 
 so velocity is doubled it would produce the greatest change in the centripetal force.

Which statement best describes the orbit of Earth?
ruslelena [56]

Answer:

B. Earth rotates on its own axis and revolves around the Sun.

Explanation:

The earth moves not only in one way but in two ways. It revolves around its axis and revolves around the Sun.

We do not notice it because we are on Earth and we turn together with it.

When the Earth revolves around its (imagined) axis, we call such a movement a rotation, and when it revolves around the Sun - a revolution.
