Answer:
true
Explanation:
think of a box, if you push it on a smooth floor without friction it would glide pretty easy
but put it on say carpet, the friction from the carpet would not allow the box to move very far
that's also how brakes work, they apply friction to the wheels in order to get them to reduce motion
The answer to this obvious question is true
Melanin provides pigmentation to the skin and it also provides UV ray protection (which is its role in the epidermis).
Answer:
The correct answer is b glucose is broken down into two pyruvate molecules.
Explanation:
Krebs cycle is one of the most important step of aerobic respiraion.Krebs cycle occur within mitochondrial matrix.During krebs cycle the acetyl CoA generated from pyruvate reacts with oxalo acetate in a cyclic manner to regenerate 4 carbon compound oxaloacetate.
During krebs cycle pyruvate is broken down or oxidized to form 2 carbon compound known as acetyl CoA and carbon dioxide as byproduct.
But the breakdown of glucose into two pyruvate molecules occur during glycolysis.
