Explain how living organisms gain and use mass through the process of photosynthesis

Biology

irinina [24]3 years ago

<span>Answer: Using energy from sunlight, photosynthesizers manufacture food (carbohydrates) from air (carbon dioxide) and water, and dump the waste product (oxygen) back into the air. So they gain mass (energy) which is utilized in many ways (e.g., food storage, procreation, structural support, protection, and much more).</span>

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
Katyanochek1 [597]

Answer:

Both boxes have the same amount of empty space

Explanation:

Given

Cube Box

Length = 10cm

Robert:

1 glass marble

Diameter = 10cm

Susan:

1000 glass marble

Diameter = 1cm

Required

Whose box has more empty space?

First, we need to calculate the volume of the cubic box.

Volume = Length^3

Substitute 10cm for Length

Volume = 10^3

Volume = 1000cm^3

Next, calculate the volume of Robert's glass

Volume is calculated as:

Volume = \frac{4}{3}\pi r^3 ---- Volume of a sphere

Where

r = radius

r = \frac{1}{2} * Diameter

Diameter = 10cm --- Given

Substitute 10 for diameter

r = \frac{1}{2} * 10cm

r = 5cm

So:

Volume = \frac{4}{3}\pi r^3

Volume = \frac{4}{3} * \frac{22}{7} * 5^3

Volume = \frac{4}{3} * \frac{22}{7} * 125

Volume = 523.8cm^3

Next, we determine the volume of Susan's 1000 glasses

Volume is calculated as:

Volume = \frac{4}{3}\pi r^3 ---- Volume of a sphere

Where

r = radius

r = \frac{1}{2} * Diameter

Diameter = 1cm --- Given

Substitute 1cm for diameter

r = \frac{1}{2} * 1cm

r = 0.5cm

Substitute 0.5cm for radius in Volume = \frac{4}{3}\pi r^3

Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3

Volume = \frac{4}{3} * \frac{22}{7} * 0.125

Volume = 0.5238

But there are 1000 glasses.

So, the volume of 1000 glasses is:

Volume = 0.5238 * 1000

Volume = 523.8cm^3

--------------------------------------------------------------------------------------------------------------

For Robert:

Volume = 523.8cm^3

For Susan:

Volume = 523.8cm^3

Since, they have the same volume.

Both boxes have the same amount of empty space
