Multicellular colonies of plant cells adhere to each other primarily by ________, whereas multicellular colonies of animal cells
Marysya12 [62]

Multi cellular colonies of plant cells adhere to each other primarily by cell walls, whereas multi cellular colonies of animal cells are typically held together by proteins

<h3><u>Explanation:</u></h3>

The organisms that contains more than single single are called as multi cellular organisms. They are just opposite to the uni cellular organisms. When many identical organisms groups to form together it is called as colonies.

It will be difficult in removing any organisms that forms colonies with the multi cellular organisms.The multi cellular organism of the cells in the plants are bonded to each other with the help of the cells walls. In animal cells these are bounded together with the help of the proteins.

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
