Describe the path of the earth around the sun.

The path that the Earth takes around the sun is called an orbit. A complete orbit occurs every year.

The path of Earth around the sun is called orbit. It is elliptical in shape. Due to the elliptical shape the the earth gets varied amount of sunlight during its revolution. It means when the earth is at 2 end of the elliptical path it gets less sunlight and when the Earth is closer path of sun it gets more sun light. This elliptical path is also responsible for season change in the Earth in addition with Earth's rotation around itself.

i believe the answer is a or 1

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
