The greenhouse effect plays a major role in the climate of a planet. Visit the Greenhouse Effect AstroTour, and use what you lea
Lesechka [4]

B. If there were no greenhouse effect, liquid water would not exist on the surface of the Earth

D. The Earth has reached thermal equilibrium, emitting the same amount of energy into space as it absorbs from the Sun.

E. The more carbon dioxide there is in an atmosphere, the stronger the greenhouse effect will be

Explanation:

The greenhouse effect plays major role in the climate of our planet in diverse ways:

  • it is responsible for the existence of liquid water on the surface of the earth.
  • it allows the earth to reach an equilibrium with space in exchange of thermal energy.
  • carbon dioxide concentration in the atmosphere has huge roles.

The greenhouse effects results from the abundance of greenhouse gases in the atmosphere. These gases are able to prevent long wave solar radiation from leaving the surface of the earth. When the gases interacts with the radiation, it produces heat that warms the earth surface. Examples of these gases are carbon dioxide, methane, water vapor e.t.c.

The warming of the surface helps to free freshwater trapped as ice and keeps it in the liquid form throughout.

In this exchange of energy, there is a balance between the amount of heat absorbed and radiated back into the atmosphere. As energy enters the earth, it is also radiated out into space. This helps to keep the earth temperature in balance.

Allow for the identification of many toxins in a small amount
lilavasa [31]

Answer:

O4) Screening tests

Explanation:

The screening test is used to make early detection of diseases in order to apply effective treatments. For example, a screening blood test enables the identification of toxins and/or drugs in the patient's system in a relatively low amount of time (generally 24 hours). This bioassay is used for the toxin determination of the effluent sample (i.e., a sample collected and analyzed to evaluate system performance) to the tested species. The screening test generally consists of applying two treatments (i.e., one effluent sample and one control).
