C) The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.
Explanation:
The increase in greenhouse gas emission cannot be likened to placing an extra log on the fire to produce more heat.
In essence, the earth is not receiving more heat than usual from the sun. It is not getting more heated.
- Greenhouse gases prevents heat from being lost from the earth surface as long wave radiation.
- This in turn will warm and heat the earth surface.
- The more the greenhouse gases, the more heat that is trapped within the earth.
- The greenhouse gases is the cover that prevents heat from being lost.
- Global warming is what results.
- An increase in heating might not cause warming of the house if the house is open.
- So also, if the earth receives more energy from the sun, the temperature might not increase if no greenhouse cover is available.
Other analogies shows heating(global warming) and cover(greenhouse gases) except of C.

Heavy rain fall in a region means that the river will expand in size to accommodate the xtra h20. it reshapes the shore line. moving h20 over time can change the land features.
- The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
- The schematic representation in the diagram helps in the understanding of the setup for the experiments.
- The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
- A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.
<h3>What are the four foremost factors of a managed test?</h3>
When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
- In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.
The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
- The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.
- The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.
- The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.
- The flow chart for the increase in pressure affecting the evaporation is given in the image attached.

<span>The centromeres split. The two chromatids separate, and each chromatid becomes a new chromosome. The new chromosomes move to opposite ends of the cell. The cell stretches out as the opposite ends are pushed apart.
Hope this helps! :)</span>
