Stimulus refers to events that produce a response in the body due to changes in the environment , therefore response to stimulus is essential for an organism to survive and adapt in its environment.

What is a stimuli?

A stimuli is any sensation or action that produces a response in a tissue or organ.

Stimulus is the plural noun of stimuli.

There are two types of stimulus:

external stimulus which comes from outside the body internal stimulus which comes from within the body.

The body responds to stimulus in order to adapt to changes in both its external and internal environment.

For example, when the envrionment is hot, the brain receives stimulus from heat receptors and then we start to sweat in order to cool down.

Stimulus are received by sense organs in the body

There are five sense organs in the body;

eye - for sightear - for hearing nose - for smellingskin - for feeling mouth - for tasting

Sensory receptors in sense organs receives stimulus and send it to the brain through the sensory neurons.

The brain processes the stimulus and send messages back through motors neurons to appropriate organs and tissues to act in response to the stimulus.

Therefore, response to stimulus is essential for an organism to survive and adapt in its environment.

how many grams will be produced??

Answers

Explanation:

b is correct. 30.6 g H2O is produced.

1. A student predicted the reaction between hydrogen and oxygen gas would yield 125
mL of water. However, after measuring the water formed in the reaction, the
student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?

Answers

Answer:

88%

Explanation:

percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.

110/125 = 0.88

0.88 x 100 = 88%

Which of these layers is found directly above the Earth's core?


Group of answer choices

Outer core

Mantle

Inner core

Crust

Answers

Answer: Mantle

Explanation:

there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.

Answer:

The answer depends on what you are taking about: the outer core or the inner core?

Answer: Mantle

Explanation:

If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer.  However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.  

I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.

1. Convert 1.5 moles to molecules 2. Convert 1.204x10^24 molecules to moles 3. Convert 1.5x10^20 molecules to moles 4.Convert 0.35 moles to molecules 5. Convert 15 moles H2O to atoms 6.Convert 0.75 moles CaSO4 to atoms

Answers

Answer:

Explanation:

1.5 moles to molecules

1 mole = 6.02 x 10²³ molecules

1.5 moles = 6.02 x 1.5 x 10²³ molecules

= 9.03 x 10²³ molecules

2 )

Convert 1.204x10²⁴ molecules to moles

6.02 x 10²³ molecules  = 1 mole

1.204x10²⁴ molecules = 1.204x10²⁴ / 6.02 x 10²³ moles

= 2 moles

3 ) Convert 1.5x10^20 molecules to moles

6.02 x 10²³ molecules  = 1 mole

1.5x10²⁰ molecules = 1.5x10²⁰ / 6.02 x 10²³ moles

= .25 x 10⁻³ moles

= 2.5 x 10⁻⁴ moles .

4 )

Convert 0.35 moles to molecules

1 moles = 6.02 x 10²³ molecules

.35 mole = 6.02 x .35 x 10²³ molecules

= 2.1 x 10²³ molecules.

5 )

Convert 15 moles H₂O to atoms

1 moles = 6.02 x 10²³ molecules

15 moles = 15 x 6.02 x 10²³ molecules

= 90.3 x 10²³ molecules of water

1 molecule of water has 3 atoms in total

90.3 x 10²³ molecules of water  = 90.3 x 3 x 10²³ atoms

= 270.9 x 10²³ atoms .

6 )

0.75 moles CaSO₄ to atoms

1 moles = 6.02 x 10²³ molecules

.75 moles = .75 x 6.02 x 10²³ molecules of CaSO₄

= 4.515 x 10²³ molecules of CaSO₄

1 molecule of CaSO₄ = 6 atoms

4.515 x 10²³ molecules of CaSO₄ = 6 x 4.515 x 10²³ atoms

= 27.09 x 10²³ atoms .
