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.
Answer:
C. Burying dead/religious beliefs
Answer:
The correct answer is ''dislocating bones.''
Explanation:
When the bone " pops out" or dislodges from its place (joint), a dislocation occurs. An ankle dislocation, like any other joint, occurs when the 2 articular surfaces of the ankle separate, in this case when the talus ( together with the rest of the foot) " pops out of place" and is no longer in contact with the surface of the tibia-fibula. This leads to the complete breakdown of the ligaments that hold the joint in place, causing the bones to " pops out." Producing significant deformities in the affected joint.
