1 answer:

Air enters into the body through nose and proceeds to pharynx or windpipe afterwards it proceeds down and reaches to larynx the voice box and continue to proceed to trachea which is surrounded by rings so that by air pressure it cannot be collapse from there a divides into two side left and right bronchus then it conducted towards bronchioles which is the pathway to alveoli at last it reaches to its Final Destination (not that movie....hahah) which is alveoli where the exchange of gases takes place

Answer:The answer is spinal cord

Explanation:

The central nervous system consists of the brain and the spinal cord.

The brain is the most highly specialized organ, and is protected by the skull or cranium, while the spinal cord is made up of soft tissue which runs from the medulla oblongata to the tail region. It is protected by the bones of the vertebral column.

The spinal cord acts as a PATHWAY between spinal nerves and the brain.

Which of the following best describes the main purpose of the combined processes of glycolysis and cellular respiration?1 breaki

max2010maxim [7]

Answer:

4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work

Explanation:

Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.

The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.

Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.

Marina86 [1]

The treatment of serious psychological disorders with prescribed medications or medical procedures that directly influence the nervous system is called <u>biomedical therapy.
</u>It is a type of therapy where medicine is used to influence physiological issues in the body, so as to treat the psychological problems of the brain. There are various ways to do this, but the most "popular" ones are drug therapies, electroconvulsive (shock) treatment, as well as psychosurgery. <u>
