The correct answer is c. smoke stacks.

Smoke stacks are chimneys or funnel shaped structures which emit smoke from a factory, vehicles and industrial set ups. Smoke stacks mostly discharge carbon dioxide and water vapor and oxides of nitrogen into the atmosphere. The exhaust released from smoke stacks cause air pollution. Air pollution can cause ailments like asthma and cancer. Thus, smoke stacks are not a source of water pollution.

How do seismic waves help scientists understand Earth's layers? Select the two correct answers. (1 point)
qaws [65]

Seismic waves help scientists understand Earth's layers by:

  • Scientists can observe how seismic waves change speeds when passing through different layers.
  • Scientists can observe which seismic waves cannot pass through certain layers.

<h3>What are Seismic waves?</h3>

These are waves which are generated as a result of the movement of

materials in the earth. They change speed as a result of the collision with

materials in the earth and know the types of material present as a result of

some types not being able to pass through certain medium.

The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to incre
spayn [35]

Answer:

The best answer to the question: The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to increased:___ would be, D: All of the answers are correct.

Explanation:

There is still a lot of debate among scientists as to the exact way in which phospholipids are distributed between the two leaflets of a cell´s plasma membrane, but what they do know is that there are four kinds, and that phosphatidylinositol (a sterol) and phosphatidylethanolamine appear most commonly on the cytosolic, or cytoplasmic side of the membrane. They also believe that it is this particular arrangement which allows the cytoplasmic side of the membrane to be slightly negatively charged and this role will play a major part in a membrane´s ability to generate an action potential. Also, it is known that these negatively charged ends of the bilayer will allow certain proteins, positively charged ones, to be inserted, and connected to it, to become transporters, or mediators in action potentials and normal activities of cells. Finally, since fatty acids and cholesterol are associated with phospholipids, but have a tendency to be attracted to these particular two types, they tend to give the overall structure fluidity, but also permit  the inner leaflet to assume its particular circular shape around the cytoplasm. This is why the answer is D.
