Hope this helps :D
Answer 2
Answer: To write 299,792,458 in scientific notation:
1) Move the decimal point to the left to where the number is between 1-10. This new number will then be multiplied by a power with 10 as the base. 
The new number is 
2.99792458, since it's between 1 and 10.

2) Count how many times the decimal point was shifted to the left. That will be the exponent for the 10.
The decimal point was moved 8 times to the left. That means the power is 
10^8

3) Take the new number to 4 significant figures. All numbers other than 0 are considered significant figures, so we don't have to worry about the rules relating to 0! Take the first four numbers and round using the fifth.
2.99792458 > 2.9979
2.9979 rounds to 2.998

4) Multiply the number rounded to 4 significant figures, 2.998 (part 3) by the power, 10^8 (part 2), to get the proper scientific notation:
2.998 * 10^8

------

Answer:
2.998 * 10^8

Answer:

The correct option is A) Photosynthesis rates will likely increase.

Explanation:

Photosynthesis can be described as a process in which carbon dioxide and water are converted into oxygen and glucose in the presence of sunlight. It is a process by which plants tend to make their own food by using carbon dioxide, water and light energy from the Sun. Hence, the higher the amount of carbon dioxide in the atmosphere, higher will be the amount of photosynthesis to occur.
