Answer:
C. Two oxygen atoms
General Formulas and Concepts:
<u>Types of Bonds</u>
- Covalent Bonds - forms between 2 non-metals
- Ionic Bonds - forms between a non-metal and a metal
- Metallic Bonds - forms between 2 metals
Explanation:
Any metal forming a compound with an non-metal is an ionic bond. Therefore, A and D are incorrect.
- Fe (Iron) is a Transition Metal forming an ionic bond with O (Oxygen), a non-metal.
- Na (Sodium) is a Alkali Metal forming an ionic bond with Cl (Chlorine), a non-metal.
Any 2 metals forming bonds with each other is a metallic bond. Therefore, B is incorrect.
- Na forms a metallic bond with Na.
Any 2 non-metals forming bonds with each other is a covalent bond. There are 2 types of covalent bonds: non-polar and polar.
- O forms a covalent bond with O.
Therefore, our answer is C.
The answer for this question is C ✨
Answer:
The first two are more closely related to each other than they are to the third.
Explanation:
The question tells us that the first two organisms share many common characteristics with each other, this tells us that the first two are related. We can cross out answer choice a. The question also tells us that the first two have very few characteristics in common with the third organism. With this much info given, the answer choices left are:
- Relatedness of the three organisms depends on the characteristics the first two share.
- The first two are more closely related to each other than they are to the third.
- The first two are equally related to the third.
First choice doesn't make any sense, there is no correlation between the common characteristics of the first two with the 3 organisms as a group.
Second choice makes sense and logical.
Third choice is wrong since the question does not give us enough information to know the first two is equally related to the third.
The first two are more closely related to each other than they are to the third. Is the right answer.
They are all acids and acids have the property of giving up a proton (hydrogen ion) in a buffer system for example.
Fatty acids only
Acetyl coenzyme A is a biological molecule that is used in biochemical reactions. These biochemical reactions include the breakdown or hydrolysis of protein, carbohydrates and lipid molecules. The hydrolysis of these molecules in the presence of acetyl CoA produces energy and its primary function is fatty acid metabolism.
