I'm pretty sure it's lactate on lactic acid.
Breathing(CO2) of plants for making food that is eaten by animals.and expelling the carbon from animal's body by breathing or defecation
The correct answer is the third one
It protects the organs of the body. Think about this..... Your bones are arranged so that each organ is protected. Each bone is like a border so that your organs are not exposed. If you didn't have bone then, if you got hurt then your vital organs could get hurt. It doesn't eliminate wastes from the body because that's the excretory system. It doesn't produce facial expressions since that is the nervous system ( heat is also controlled by the nervous system).
Acid-fast and Gram is used to visualize the structures in a membrane.
It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>
Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.
They stain poorly with Gram stain procedure, and appears as weak Gram-positive.
Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids, and
<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>
To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.
