Scientist: A greenhouse gas, for example, carbon dioxide, forms a transparent layer that traps solar heat beneath it in the eart

h's atmosphere. Atmospheric levels of carbon dioxide are currently increasing, causing the climate to warm-an effect that is predicted by at least one computer model of the greenhouse effect. But the warming that has occurred is a great deal less than what would be expected based on the model. Therefore, _______.
Which of the following most logically completes the scientist's argument?

A. better measurements of atmospheric levels of carbon dioxide are needed
B. the definition of "greenhouse gas" should probably be reconsidered
C. there are factors besides the increase in greenhouse-gas emissions contributing to the warming of the climate
D. the computer model of the greenhouse effect must be incorrect in some respect
E. the likely consequences of any warming of the climate are unlikely to be much less damaging than predicte

Answer:

D. the computer model of the greenhouse effect must be incorrect in some respect

Explanation:

According to the scientists, carbon dioxide is playing a major role in green house effect. Increasing carbon dioxide level in the atmosphere is also leading to an increase in global warming. To predict this situation, a computer model of greenhouse effect is also created. It aims at predicting the warming level based on some simulations.

However the model's prediction does not match with real life observations. It predicts the warming to be lot more than observed in reality. This error can be a result of some technical issue in the computer model. Also, real life observations are based on many factors and the given computer model is based just on the level of carbon dioxide in atmosphere. So it might have calculated incorrect warming level.

Can someone help me? The question is State two scenarios that demonstrate the process diffusion​
gtnhenbr [62]

Answer:

One could be in the cell. The cell respires, thus producing carbon dioxide in it. So the concentration builds up in the cell. Diffusion is the net movement of particles from a region of high concentration to a region of low concentration, and the carbon dioxide concentration outside the cell is less, therefore the carbon dioxide molecules moves outs of the cell.

Another scenario is when perfume is sprayed into the air. The perfume particles collides with the air particles (lower or no concentration of perfume). This process goes on and on. This is diffusion since the concentration perfume particles collides with the less concentrated particles of perfume.

Describe the process by which coral polyps and algae create a coral reef.
xenn [34]
Coral reefs are built by coral polyps as they secrete layers of calcium carbonate beneath their bodies.  And inside each coral poly lives single-celled algae called zooxanthellae. So basically in simplistic terms, coral polys create coral reefs and algae is in coral polys which also goes into coral reefs when they are made.
