Answer:

You are correct it's the earth!

Explanation:

The reason why is because, the term "elliptical orbit" is used in astrophysics and astronomy to describe an oval-shaped path of a celestial body. The Earth, as well as all the other planets in the Solar System, follow this type of orbit around the Sun. The shape is created by the varying pull of forces, such as gravity, on two objects, such as the Sun and a planet.

Hope this helps! :)

Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.

Answer: Closed

Explanation:

At  resting membrane potential( RMP) sodium channels remained shut, this is because , previously  in depolarisation,the  voltage  gated sodium  channels  were opened for sodium to diffuse  into the Axon. However   these channels closed  after reaching their refractory period,s.

Therefore a  change  in the extracellular concentration of sodium will not  open them
