Which of the following is NOT an example of lentic ecosystem?

Which of the following is NOT part of the respiratory membrane of the lungs

Bumek [7]

That which is NOT part of the respiratory membrane of the lungs is:

A thin layer of ciliated epithelial cells

<h3>What is the respiratory membrane?</h3>

The respiratory membrane is the surface of the lungs where there is an exchange of gases. There are many parts that make up the respiratory membrane of the lungs.

Some of these are; the respiratory mucosa, the adventitia, and the submucosa. The thin layer of ciliated epithelial cells is not a part of the respiratory membrane but is a hair-like structure that helps to remove unwanted substances from the body.

So the correct answer is: a thin layer of ciliated epithelial cells.

What mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C?.

bogdanovich [222]

The mass of glucose solute dissolved in the solution is 6.739 Kg.

Recall that;

ΔT = K m i

ΔT = Freezing point depression

K =Freezing point depression constant = 1.86°C/mol

m = molality of the solution

i = Van't Hoff factor = 1 (molecular solution)

We have to find the freezing point depression from;

Freezing point depression = Freezing point of pure solvent - Freezing point of solution

Freezing point of pure water = 0°C

Freezing point of solution = -5. 8 ∘C

Freezing point depression = 0°C - (-5. 8 ∘C) = 5. 8 ∘C

Now;

m = ΔT/K i

m = 5. 8 ∘C/ 1.86°C/mol × 1

m = 3.12 m

But molality = number of moles of solute/mass of solvent in Kg

Molar mass of solute = 180 g/mol

Let the mass of solute be m

3.12 = m/180/12

3.12 = m/180 × 12

m = 3.12 × 180 × 12

m = 6739 g or 6.739 Kg

Briefly explain one way the address in the excerpt provides information about the broader international context within which it

Citrus2011 [14]

Based on the excerpt, President Jimmy Carter made reference to the meeting he had with various leaders on the energy crisis.

<h3>What is a state crisis?</h3>

A state crisis can be defined as any form of event that has the potential of causing an unstable and dangerous situation across a country, thereby, adversely affecting the people that are living within it.

In this scenario, the United States of America had an energy crisis while Jimmy Carter was the president. Thus, President Jimmy Carter gave a speech on the 15th of July, 1979 to address the citizens of the United States of America on their energy crisis through a live TV broadcast.

Can a puddle of water erode soil yes or no ASAP.

Radda [10]

Answer:

Puddles of water seen after a rainstorm that are clouded with sediment suggest erosion is occurring whereas puddles of clear water are a sign of minimal erosion. Lighter colored soil seen overtime is also a sign of erosion but can be more difficult to identify.
