15 1. carbon has valence electrons allowing it to easily with other molecules. 2. is the ability of water to bond to itself. 3. is the ability of water to bond to other molecules.

1. four, bond
2. Cohesion
3. Adhesion is correct ... looked in my bio book sorry

1) Carbon has 4 valence electrons allowing it to covalently bond easily with with other molecules.
2) Cohesion is the ability of water to bond with other water molecules.
3) Adhesion is the ability of water to bond to other molecules.

** Both Cohesion and Adhesion are due to hydrogen bonding present because water is a polar molecule.

1. when the tempature rises,your sweat glands and then springs into action making perspiration. some sweat evaporates with your skin taling heat with it.2.some of the blood pumped by the heart travels by your lungs to get rid of carbon dioxide and pick up oxygen.3.saliva produces by, you drinking water which saliva is 98% of. when mucus builds up in your body it also creates saliva as well as, antibacterial compunds.4.when the core body tempature drops, the shivering reflex is triggered to maintain homeostasis. for example: when you get out the pool you start to shiver because it is cold.
