Answer:
2(h - 8) - h = h - 16 2. 4(x - 3) + 5 = 1 3. 70 = -7(-2 -2z) 4. -2x + 4 = 2(4x-3)-3(-8+4x
Explanation:
2(h - 8) - h = h - 16 2. 4(x - 3) + 5 = 1 3. 70 = -7(-2 -2z) 4. -2x + 4 = 2(4x-3)-3(-8+4x
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
Answer: The function of the coded instructions contained in the body cells of an organism is called the Genes

Answer:
A. Urethra
Explanation:
The part highlighted below is also known as the Urethra, or the tube in which the urine or semen travels in the male reproductive system! :)
Answer: Diffusion
Explanation:
Diffusion is the process or a spontaneous movement of particles from an area of higher concentration to an area of lower concentration.
Examples are;
1. perfume
2. A drop of ink in a cup of water.
From these two examples when it is dropped, especially ink, it diffused inside the entire space of the cup and fill all the space by penetrating the entire molecule of the water available.
