predict what might happen if the respiratory membrane were instead composed of two layers of stratified squamous epithelium

Biology

Ulleksa [173]3 years ago

The prediction is: if the simple squamous epithelium in lungs is replaced by stratified epithelium, The respiratory membrane will not be permeable to the exchange of oxygen and carbon dioxide.

The simple squamous epithelium covers the surfaces ensuring the passive transport (diffusion) of either gas (as in the lungs) or liquids (as in the walls of the blood capillaries).

Simple squamous epithelia also form the delicate lining of the pleural, pericardial and peritoneal cavities where it allows the passage of tissue fluid into and out of these cavities. Although these cells appear to be simple in shape, they have important and varied roles.

The stratified epithelium is not involved in significant uptake, in permeability of molecules, or in secretory activity, but merely provides a more robust coating than would be offered by a single epithelium.

If the respiratory membrane is composed of two layers of stratified squamous epithelium, it will mostly contain numerous cell layers because it is its composition of having to be a stratified squamous epithelium. Another thing, the tissue will most likely be a shield for this type of epithelium will serve as a protection against abrasion of which the respiratory membrane will be protected of.

The tempter was already cast out of heaven before the Fall of man. True False
Katena32 [7]

I would say "false" or the second option. Satan was still a angel he just tricks Adam and Eve into doing the one thing God asked them not too and then God cast Adam, and Eve out and Satan became Satan. Which means that the tempter caused the fall of man while he was still a angel.

Hope this helps.

Inhibitors of the electron transport chain exert their effects through a variety of mechanisms.
Vladimir [108]

Answer:

Azide and Carbon monoxide block electron transport and proton pumping via inhibition of Complex IV.

Rotenone blocks electron transport and proton pumping via inhibition of Complex I.

Atractyloside blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.

Explanation:

The mitochondrial electron transport chain is composed of different complexes integrated into the inner mitochondrial membrane, which function to generate an electrochemical proton (H+ ions) gradient that is then used to drive the synthesis of ATP, the energy coin of the cell. The mitochondrial complex I catalyzes the electron transfer from nicotinamide adenine dinucleotide (NADH) to ubiquinone and then transports H+ ions across the inner mitochondrial membrane. Moreover, the mitochondrial complex IV, also known as Cytochrome c oxidase, receives electrons via the cytochrome pathway in order to complete the reduction of oxygen (O2) into two molecules of water (H2O). Azide is a selective inhibitor of the complex IV which acts as an uncompetitive inhibitor with regards to O2, while carbon monoxide (CO) binds to the cytochrome c oxidase enzyme, thereby suppressing its activity and thus disturbing ATP synthesis. Rotenone is a potent inhibitor of the mitochondrial complex I that inhibits electron transfer from the iron-sulfur centers in the complex I to ubiquinone, thereby blocking ATP synthesis. Finally, atractyloside is a competitive inhibitor that inhibits the transport of ADP across the mitochondrial inner membrane by blocking the ADP/ATP translocator, thereby preventing ADP from entering mitochondria.

Dora loves dark chocolate. Recently she read the Nutrition Facts panel on the wrapper of her favorite chocolate bar. She was sho
Dmitry [639]

Answer:

The statement that should help Dora evaluate whether dark chocolate is a heart-healthy choice is a group of answer choices Chocolate contains stearic acid, which does not appear to increase LDL cholesterol levels. LETTER A.

Explanation:

<em>Because consuming dark chocolate  decreases oxidized LDL cholesterol in the heart and also increases HDL. The decrease of oxidized LDL means that the bad cholesterol has reacted with free radicals. The dark chocolate contain a powerful source of antioxidants that go into the bloodstream and protect lipoproteins against oxidative damage.</em>

<em>So it will improve several important risk factors for heart failure. That is the right choice for Dora.</em>

If a scientist turns a polymer into a monomers in the laboratory would the resulting material be larger or smaller than the star
Goshia [24]
If you are talking about the amount of material, it will be equivalent. But monomers are usually smaller than polymers.
