How might each of the following parts of the brain be active while we drive a car? Cerebellum

The correct answer is -  the cerebellum helps us to use our hands to turn right or left.

Explanation:

Different parts of the brain play or are active on different functions during complex work done by us. Their activity helps in proper functioning and smooth work. During driving different parts of the brain to become active to work specific functions. Some parts of the brain and their function are:

cerebellum  - helps to utilize hands to turn right or left

Medulla  for breathing and have a steady heart rate

pons  - alertness

reticular formation  - avoid drowsiness

thalamus  - respond to sound such as car horns  

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!
