The process in which green plants use sunlight to make their own food.
Photosynthesis is necessary for life on Earth.
Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
It is the number one source of oxygen in the atmosphere.
First, let calculate the volume of the rod shaped-bacteria:
S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3
Now, let's convert the moles into molecules (with Avogadro's law):
0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L
Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)
1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3
so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3
The answer is 2.22 10^ 12 molecules / µm3
Answer:
The correct option is;
7:32 AM
Explanation:
The information given are;
The time at 45 degrees W and 72 degrees N = 9:32 AM
The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location
Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted
The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM
The latitude of a place left out in the calculation of the relative time of a place.
