The three stages of Action Potential are:
1. depolarization- Na+ channels open up inside of the membrane and becomes more positive than the RMP.
2. repolarization- The Na+ channels inactivating and K+ channels opening AP spike stops rising to which the membrane returns to RMP.
3. hyperpolarization- A few of the <span>K+ channels remain open and the Na+ channels reset inside of membrane becomes more negative than RMP.
Hope this helps!

<span>the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation. The fluid then flows through the nasolacrimal duct and into the nasopharynx. This drainage results in what is commonly referred to a runny nose during excessive crying or tear production. Injury or fracture of the lacrimal bone can result in posttraumatic obstruction of the lacrimal pathways</span>
Answer:
Option B , synthesizes ATP.
Explanation:
When the inner mitochondrial membrane is intact, ATP is synthesized. ATP is synthesized from ADP and Pi by electrons from NADH or FADH2 to O2. This process is known as oxidative phosphorylation which is driven by an electrochemical proton gradient across the inner membrane with three processes occurring simultaneously
a) electron transport,
b) proton pumping, and
c) ATP formation
Hence, option B is correct
If more forests were cut down, then the amount of CO2 in the atmosphere would increase
Hypothalamus is a part of the brain that links the nervous system to the endocrine system via the pituitary gland. It helps maintain the internal environment constant by regulating major processes in the body such as the heart rate and the body temperature. It is therefore, both a neural and endocrine organ.
