Answer:
C
Explanation:
Breaks are called faults, and the 2 tectonic plates at the fault move and they can squeeze together to form a mountain. They can also form earth quakes like that. Volcanoes can be formed by 2 tectonic plates that move apart
Solution:
The four main types of macromolecules found in living organisms, are as follows:
• Proteins.
• Carbohydrates.
• Lipids.
• Nucleic Acids.
Macromolecules are large, complex molecules. It is the product of many smaller molecular units. It is also known as Polymer
Thus the required answer is proteins, carbohydrate, lipids, and nuclear acids.

Then the correct answer would be C - parents who are heavily invested in their children may suffer from a decline in marital satisfaction after children have left home. This also makes sense; they've been parents and not husband and wife. For that reason, following the child's departure, they're not sure what to do with themselves.</span></span></span>
Answer:
Two back-to-back phospholipid layers with the polar heads facing out on both sides
Explanation:
Phospholipids are made up of a head and two tails. The head can be described as a phosphate molecule that is water loving (hydrophilic) whereas fatty acids make up the two tails. The fatty acids repel water and hence are hydrophobic. The assembling of the phospholipids for the the formation of cell membrane depends on these hydrophilic and hydrophobic properties. The assembling of the phospholipids is in two layers. The phosphate head face outwards on both sides to attract water and the tails tend to hide from the water molecules by being composed in the layers of the head. this assembling is termed as the "self-assembly".
