Answer: A. Cool
Explanation:
The diagram shows that moving from the left to the right indicates a lower temperature and the arrow is pointing to stars to the right which means that they are cool in comparison to those on the left.
Red stars like the one being pointed to are the cooler stars with temperatures of less than 6,000 Kelvin as opposed to blue stars which are very much hotter and go above 10,000 Kelvin.
The inside of your nose is called the nasal cavity. A mucous membrane lines your nasal cavity and it helps keep your nose moist. Little hairs inside your nasal cavity help filter the air you breathe in and block dirt and dust from getting into your lungs.

Answer:
Chemical weathering
Explanation:
Chemical weathering is the process when rain chemicals react with rocks and minerals. In this process, the rocks are weakened. This chemical happening provokes the chemical reaction in the rock or in the mineral.
Chemical weathering is a spontaneous process and it leads to a more stable state for natural materials under a given set of conditions.
The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material
Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.
