Answer:
Simple squamous epithelium,stratified squamous epithelium,pseudostratified columnar epithelium
Explanation:
The respiratory system is made up of many different types of tissues and they differ according to their locations in the respiratory system.
1.Simple squamous epithelium: It is found within the alveoles of the lungs. These cells are single layer,flat (squamous) cells. It controls the permeability of blood vessels in the lungs. When you inhale it allows more oxygen to be absorbed in the blood flows.
2.stratified squamous epithelium: It is found at mouth surface primarily tongue and throat . These cells are stratified that is they are many layered because everyday whatever we put in our mouth and throat it protects from wear and tear. It gives physical protection from pathogens as well.
3.pseudostratified columnar epithelium: It is a lining of the nasal cavity trachea and bronchi. This layer is ciliary to trap patheogen on entering into the lungs.

For lactic acid fermentation, the correct options are:
- pyruvate
- hydrogen
- NADH
- lactic acid
- Lactic acid
- pyruvate
- mitochondria
For ethanol fermentation, the correct options are:
- pyruvate
- CO₂
- acetyl CoA
- acetyl CoA
- acetaldehyde
- Acetaldehyde
- hydrogen
- NADH
- ethanol
<h3>What is a anaerobic respiration?</h3>
Anaerobic respiration is respiration which occurs in the absence of oxygen.
Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.
Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.
In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.
On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.
After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.
In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.

Answer: "diffusion" .

-20 is the answer it’s pretty simple
From the right atrium, the deoxygenated blood drains into the right ventricle through the right atrioventricular (AV) valve, which is so named because it is between the atrium and the ventricle. This valve is also referred to as the tricuspid valve because it has three flaps in its structure. When the ventricles contract, the AV valve closes off the opening between the ventricle and the atrium so that blood does not flow back up into the atrium.As the right ventricle contracts, it forces the deoxygenated blood through the pulmonary semilunar valve and into the pulmonary artery. Semilunar means half-moon and refers to the shape of the valve. Note that this is the only artery in the body that contains deoxygenated blood; all other arteries contain oxygenated blood. The semilunar valve keeps blood from flowing back into the right ventricle once it is in the pulmonary artery.The pulmonary artery carries the blood that is very low in oxygen to the lungs, where it becomes oxygenated. i hope this helps you
