Answer: All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Answer:
35g/l
Explanation:
Salinity is practically the saltiness of the water, in basic terms. It's basically the amount of salt dissolved in water. Ocean water has a salinity of around 35g/l (that's about 3.5% of which is dissolved salt in water!). However, Atlantic Ocean (the ocean with the saltiest water), can range up to 37g/l.

Answer:
- Lipids: used for long-term energy storage
- Nucleic acids: used for storing and transmitting genetic information
- Protein: used for tissue repair and growth
- Carbohydrates: used for energy
Explanation:
These terms simply have to be memorized, but understanding their structure can help you gain a better grasp of their functions. Lipids have fatty acid chains with lots of bonds, so they are high energy. Nucleic acids have pieces that can be rearranged into many combinations that can be read by certain structures. Proteins are composed of different building blocks with different properties. The sum of these properties is the function of the protein. Lastly, carbohydrates have compact monomers that are extremely easy to break apart into energy.
