The nucleus. It is basically the control center of the cell. It makes sure everything is running, just like our brain does. I hope this helps!
The change in internal energy of this gas sample is equal to: c. 715 J.
<u>Given the following data:</u>
- Quantity of heat = 874 J.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:
Where;
- is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;
Change in internal energy (ΔH) = 715 Joules.

Answer:
1. Liver
2. Pancreas
3. Lungs
4. Saliva
5. Small intestine
6. Large intestine
Explanation:
1. Liver is a large, infact the largest, organ found in the digestive system. It has variety of functions ranging from detoxification to digestion. The liver functions in digestion by secreting a substance called BILE which helps in the breakdown of fat in the small intestine.
2. Pancreas is another accessory digestive organ which serves as a endocrine organ which secretes enzymes that aid in the digestion of protein and carbohydrate molecules.
3. Lungs are respiratory organs whose function is key to the respiratory system. They are the organs that serve as a medium of the entry of oxygen and removal of carbon dioxide, a process called GAS EXCHANGE.
4. Saliva is a liquid substance secreted by the salivary gland in the mouth. Saliva contains certain enzymes; most notably is the AMYLASE that breaks down starch into sugar.
5. Small intestine is another organ in the digestive system composed of the ileum, jejenum and duodenum. The small intestine is the organ where the absorption of nutrients into the blood from the digested food takes place.
6. Large intestine is the extension of the small intestine whose function is to absorb extra water from undigested food and pass out the remaining as feaces.
<span>since water is a Liquid it can be in a beaker or test tube but you need a thermometer if a beaker you use a hot plate if test tube you use a Bunsen burner</span>
Food and water? If we don't eat or drink we die so therefore that is our energy source.
