Answer: A. They absorb radiation given off by the earth.

Explanation: Green house gases are gases that have the capability of trapping the heat energy from the sun in our environment. These special attribute of these gases is what keeps our environment warm and sustain life as we know it. Example of Green House Gases include: carbon dioxide, water vapour and methane.

Answer:

A. THEY ABSORBS RADIATION GIVEN OFF BY THE EARTH.

Explanation:

Greenhouse gases are gases capable of absorbing and emitting infrared  radiations in different wavelength range emitted by the earth. These gases include water vapor, carbon iv oxide, methane, ozone, chlorofluorocarbons, nitric oxide, hydrofluorocarbons. These gases contribute to the greenhouse effects and there actions are dependence on their respective characteristics, abundance in the atmosphere and the indirect effects it causes. Earth surfaces absorbs radiant energy from the sun and these radiations are reflected as light or reflected back to space as hear. Greenhouse gases are involved in absorbing and emitting these incoming energies in order to create a balance between the incoming and outgoing energies. This determines the temperature on the earth surface. The earth can be warm or cold depending on the direction the difference in this balance shifts. Without the greenhouse gases the average temperature of the earth will be lower than the expected temperature.

Write the answer in scientific notation when you multiply 2 x 104 by 3 x 104.
emmasim [6.3K]

Answer:

6× 10⁸

Explanation:

We need to find the multiplication of 2 x 10⁴ by 3 x 10⁴.

2 x 10⁴ × 3 x 10⁴

= (3 × 2) x 10⁴ x 10⁴

= 6 x 10⁴ x 10⁴

= 6 × 10⁴⁺⁴

= 6× 10⁸

Hence, the required answer is 6× 10⁸.

What does your data indicate about the optimum ph level for this enzyme-catalyzed reaction?
mestny [16]
At an optimum pH of 7.0, there are more molecules per minute in all amounts of substrate thus this pH is ideal for maximum growth. 5. Enzymes function most efficiently at the temperature of a typical cell, which is 37 degrees Celsius. Increases or decreases in temperature can significantly lower the reaction rate.

How is electromagnetic energy fromthe microwave transformed into heat energy
zysi [14]

Answer:


First, the microwaves transmit kinetic energy to the water molecules of the food, heating the water molecules. Only, those that are not very deep into the food.


Second, the hot water molecules transmit heat by conduction to the other parts of the food.


Explanation:


1) Microwaves are a form of electromagnetic radiation. The same as any wave, they carry energy.


2) The wave length of microwaves are in the range of 0.001 mm to 1 m (shorter than radio waves and longer than infrared)


3) The microwaves of an oven, used to heat food, have a wave length aroun 12 cm.


4) The microwaves transmit energy to the water molecules in the food, by increasing the kinetic energy of water molecules. As result, the water molecules get hotter. Microwaves only penetrate about 1 cm inside the food (a potato for example) and from that the heat is transferred by conduction to the inner parts of the food.
