Functional group responsible for the cross link in a protein structure

Sulfhydryl Group (-SH)

100

What is the type of bond that occurs between  hydrogen and oxygen elements, in two separate water molecules?

Hydrogen bond

100

What solution in the "Chemical Analysis of Food" allowed for the viewer to see the presence of simple carbohydrates?

Benedict's Solution

100

An example of this process is the ability for trees to retain water against the effects of gravity?

Cohesion

200

Explain why reductionism is important for classifying all life on Earth?

Reductionism is the process of reducing complex systems to more simple manageable systems, which affects how life is characterized because life is based upon the hierarchical organization of all organisms.

200

What is the functional group found in all proteins?

Carboxyl Group

200

What type of bond occurs between Carbon(2.55 electronegativity) and Potassium(.90 electronegativity)?

Ionic bond

200

The water in the Iodine solution test was what type of experimental group used in research?

Negative control

200

An example of this property of water would be a dogs ability to cool off by panting?

Evaporative cooling

300

Why is variation important for a species?

Variation increases the chance of survival, which results in a species being around longer.

300

What is the functional group that acts as a base for some chemicals?

Amino group

300

Name the bond that joins the two elements below?

Oxygen and Flourine

Non-polar covalent bond

300

How does a hypothesis differ from your prediction when experimenting?

A hypothesis is a statement used to further test on and elaborate, while a prediction claims what will happen in the experiment by assuming your hypothesis was correct.

300

An example of this property of water is provided by the cool moderate temperature present in coastal cities like San Diego?

Temperature modification


by the way if you can, visit San Diego it is very lovely :)

400

How many covalent bonds does CO2 have?

4

400

What is the functional group that contributes to the molecules ability to react with water, in which the reaction would release large amounts of energy?

Phosphate group

400

What is the type of bond that occurs between Carbon and Hydrogen, that in result aids in the process of the synthesis of simple sugars like sucrose?

Polar covalent bond

400

What was the name of the factor affecting the population of stickleback communities in both Frog and Bear Paw Lakes?

Environmental factor

400

As pH increases in a solution, what happens to the hydroxide ions?

Hydroxide ions steadily increase

500

Name this functional group:

CH4

Methanol Group

500

What is the functional group that has the same elements needed to form a simple sugar?

Carboxyl group

500

What type of bond occurs in the compound of NH3?

non-polar covalent bond

500

Why was vegetable oil when testing for lipids an important inclusion when using the Sudan IV in the "Chemical Analysis of Food" lab?

The inclusion of the vegetable oil provides the experiment with a positive control. This was important because it provided a source to look back on in order to determine the validity of the experiment. It provides the experiment with the correct expected result.

Explain why fatty acids are not soluble in H2O, while including the reasoning of H2O's capabilities to bond with certain compounds?

Fatty acids and water cannot bond because water forms through polar covalent bonds, and fatty acids form through non-polar bonds, so there would not be a correct amount of valence electrons in order to exchange.
