Answer:
1. False
2. True
3.True
Explanation:1. Polar molecules have two regions but the regions are with a partial +tive charge and a partial -tive charge
2. Water is a polar molecule because of the partial +tive and partial -tive charge hence it dissolves polar solute(solute with ions)
3.The more electronegative region bonds with an electrophile to form a weak bond(Hydrogen bond)
Answer:
Advantages: Wind turbines do not actively create green house gases, wind is an indirect solar energy (which means it never runs out), and it has a fairly high net energy
Disadvantages: NIMBY effect (not in my backyard, it means people support it, but they don't want to be near it), transportation and construction of materials cause greenhouse gases, and wind turbines can kill/harm birds and bats
Explanation:
Gathering, constructing and transporting materials to build wind turbines releases green house gases, because of vehicle's combustion and factory emissions. However, wind turbines rely on a renewable resource that a) never runs out, and b) is a clean source of energy. Compared to nonrenewable energy sources, wind is a good energy source.

Answer:
c) Gives a cell its distinctive characteristics
Explanation:
Carbohydrates perform two main functions in the cell's membrane: <em>they participate in cell recognition and adhesion</em> (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.
Most of the carbohydrates linked to the membrane are in the form of <em>glycoproteins oy glycolipids</em>, these are the molecules that share information and recognize host cells. <em>Glycocalyx </em>is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.
