1. which of the following is a density-dependent limitation on population growth?
a. wildfire
b. competition
c. pollution
d. severe drought

2. human activities that increase carbon dioxide in the atmosphere are likely to cause which of the following environmental changes?
a. decreased plant growth
b. tsunamis
c. an ice age
d. a higher sea level

3. which of the following is the tendency of a water molecule to stick to other waste water molecules?
a. cohesion
b. density
c. adhesion
d. buoyancy
4. water has many unique properties that allow it to support life. identify three of these properties and explain how each is important to organisms.

1) B
    (I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition

2) D
    Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.

3) A

4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.

Swating at a bee and it stings

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
