How do plants use nitrogen?

antoniya [11.8K]

Answer:

Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

Andrew snacks on high-carbohydrate and high-fat foods during his afternoons on Mondays through Thursdays. In fact, when he total

yulyashka [42]

Answer:

Andrew is consuming extra 200 kilocalories every day. These calories are not required by the body so it will store them for further use.

Most of the extra carbohydrate will enter glycogenesis pathway to form glycogen which will be stored in liver and skeletal muscles.

Remaining carbohydrate and fat will enter the lipogenesis pathway will get converted into triglycerides which will be stored as fat in adipose tissue.

Excess storage of calories can make Andrew overweight in future.

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
