c. Factors 1 and 2 may be influenced by both nature and human factors
Explanation:
The sea level rising and the change in the atmospheric gases are both processes that are influenced by the nature, as well as by the human activities. Naturally, the earth has its own cycles, known as Milankovich cycles, through which the Earth warms up, or cools down, resulting in change of the atmospheric gases, and in accordance to that, change in the sea levels depending on the global climate. The humans to have become a big factor in the past few hundred years. The reason for that is that the humans with their activity started to release lot of greenhouse gases into the atmosphere, especially CO2 and methane. That has been changing the composition of the atmosphere, and the temperatures have been rising. The higher the temperatures, the more ice is melting around the poles and on the high mountains, resulting in an increase in the sea levels.

Covalent bonds are formed when two atoms are able to <em>share</em> electrons.
Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.
<u>Covalent bonds:</u>
- Have a definite shape.
- Have a low melting point.
- At room temperature they are in a liquid or gas.
- They occur between two non-metals.
<u>Ionic bonds:</u>
- Have no definite shape.
- Have a high melting point.
- At room temperature they are solid.
- They occur between a metal and a nonmetal.
The correct sequence of nerves that exit the spinal cord, going from superior to inferior; cervical, thoracic, lumbar, and sacral. The spinal cord is divide into four different regions; the cervical, thoracic, lumbar and sacral regions. The different cord regions can be visually distinguished from one another. There are 31 segments, defined by 31 pairs of nerves exiting the cord. These nerves are divided into 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerve.
