Hello, I did this project in seventh grade, and I still have my notebook from it! Here's the answer I wrote:

<u>A cell is like a restaurant.</u>

The cell membrane controls what goes in and out of the cell. It is like a door because it get things in and out of the cell, much like a door gets people in and out of a restaurant.

The chloroplast makes food for the cell by photosynthesis. It is like the chef because it makes and provides food for the cell, much like a chef makes food for the customers.

The nucleus controls the activities of the cell. It is like the kitchen becuase it holds information in the cell, and the kitchen holds all of the recipes.

The endoplasmic reticulum transports materials around the cell. It is like a waiter because it transports things around the cell, like a waiter transports food around the restaurant.

The mitochondria give the cell energy by breaking down food. It is like a customer becuase it breaks down food and provides energy to the cell, much like how customers eat food that the chef makes and then pay for it, so the business does well.

The cytoplasm holds the organelles and is where chemical reactions take place. It is like the building because it holds all the organelles in the cell, and the building holds all of the restaurant activity.

The vacuole stores food, water, and waste. It is like the refrigerator because both store water and food.

The Golgi bodies pack, fold, and deliver proteins. They are like the take-out boxes in a restaurant because they hold proteins, and take-out boxes pack and hold food.

I really hopes this helps!

Describe THREE things you can do to help protect the ozone layer?

Klio2033 [76]

Answer:

Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process. Some of the most dangerous gases are chlorofluorocarbons, halogenated hydrocarbon, methyl bromide, and nitrous oxide.

Minimize the use of cars. The best transport options are urban, bicycle, or walking. If you use a car, try to carpool to decrease the use of cars. This prevents pollution.

Do not use cleaning products that are harmful to the environment. Many cleaning products contain substances that are corrosive. Replace these dangerous substances with non-toxic products such as vinegar or bicarbonate.

Buy local products. Not only do you get fresh products but you avoid consuming food that has traveled long distances. The more food is transported, the more nitrous oxide is produced due to the cars or trucks used to transport it.

Maintain air conditioners, as their malfunctions cause chemicals to escape into the atmosphere.

C. At what height would the pomegranate have the same potential energy as the melon? (1 point)

zvonat [6]

Answer:

Given a set of assumptions which are given below, the height at which the pomegranate will have the same potential energy as the melon is 39.19 meters.

Explanation:

Gravitational Potential Energy refers to the acquired innate energy of an object due to its elevation above the surface of the earth.

This energy is the result of gravitational pull or force acting on the object.

In other to determine at what height a pomegranate and a watermelon will have the same potential energy we need to know the other factors in play.

Gravitational Potential Energy (E<em>p</em>)= <em>mgh</em>

Where m = Mass (kg)

g = gravitational field strength (N/kg)

h = height (m)

E<em>p </em>= gravitational potential energy ( <em>j </em>)

Let us assume that the

An average pomegranate weighs about 0.255146Kg

An average melon weighs about 10Kg
g is always constant at 9.8 N/kg

Note that melons weight much more than pomegranates.

So, let's calculate for the E<em>p </em>of the melon at the height of 1 meter

E<em>p</em> = 10 x 9.8 X 1 = 98<em>j</em>

Using the above assumptions, we do a goal seek using Microsoft Excel. Please see the attached image.

Calculation shows that the Height (h/Meters) at which the E<em>p </em>of both veggies become equal is 39.19m

This can be verified by inserting the figure and multiplying it. It can also be calculated as follows:

That is

E<em>p = 98j</em>

<em>m = </em>0.255146kg

<em>g= 9.8kg</em>

<em>h= ?</em>

98= 0.255146 x 9.8 x <em>h</em>

98 = 2.5004308<em>h (we divide both sides by </em>2.5004308 to make h the subject matter<em>)</em>

<em>h = 98 / </em>2.5004308

<em>h = 39.1932462198</em>

Which is approximately 39.19
