A grocer stacks oranges in a four-sided pyramid that is 6 layers high. Solve for the number of oranges in the pile.
Vlada [557]
Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25 
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
                                                               = 91 oranges

Len [333]

Answer:

A. It decreases the activation energy needed to start the reaction

Explanation:

Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place

When this occurs the minimum amount of  energy of  reaction to  activate or stimulate  the the atoms and molecules of the substrate to undergo chemical reaction is  lowered.This energy of reaction is celled activation energy.

Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation  energy.

All right.
Differences with the Historical Model:

<span>2. Aristotle believed in a geocentric (Earth centered) solar system, while it actually is heliocentric Sun centered). </span>
<span>3. That model didn't show all the planets we know today, such as Neptune, Uranus, etc. </span>
<span>4. A lot of that model was based on religious beliefs. 
</span>Differences with Modern Model:
1. Our model shows the orbits as ellipses. 
<span>2. Our model shows a heliocentric solar system. </span>
<span>3. Our model shows all the planets we know today. </span>
<span>4. Our model has nothing to do with religion. 
</span>Similarities Between Both Models:
1. They both are based on the same solar system. 
<span>2. They both show the inner planets, the Moon, the Sun, Jupiter, and Saturn. </span>
<span>3. The both were made by many observations of the sky.
