nexus9112 [7]

Answer:

Answer:

The correct answer will be option-B.

Explanation:

The two main processes for the survival of living organisms is the photosynthesis and cellular respiration. These processes are served different functions to the organism but they are inter-related to each other.

The cellular respiration produces the by-products in the form of carbon dioxide and metabolic water which gets utilized during the photosynthesis. The water is utilized during the light-dependent reaction where water is broken down releasing oxygen utilized during respiration.

The carbon dioxide is utilized during the light-independent reaction in the synthesis of a glucose molecule.

Thus, Option-B is the correct answer.

Which of the following is an example of radiation?
drek231 [11]

Answer: D. Our atmosphere is constantly being heated by the sun.

Radiation is the transmission of energy in the form of waves or particles released by one source and absorbed by another source. Types of radiations includes electromagnetic radiation, particle radiation, acoustic radiations and gravitational radiations.

Our atmosphere is constantly being heated by the sun is the example of the radiation because the sun radiates energy in all directions in the form of heat, light and radiations. Solar energy in the form of radiation is either reflected back to the sun or it is absorbed by the earth atmosphere. Therefore, this causes heating up of the earth atmosphere.

Pretend that you are writing a letter to the president proposing ways that the US can reduce its contribution to climate change.
ahrayia [7]

Answer:

Dear Mr. President,

Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.

Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.

Sincerely,

hope this helps!
