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.

Explanation: Renewable resources are resources that we can keep using without depleting the earths natural resources. Turbines and the waterfall are endless, not using up anything.
Answer:Dna template- 5' ACTCCTGAA 3'
3' TGAGGACTT 5' complementary base
Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base.
Replication occurs in 5' to 3' direction.
For complementary base in DNA Adenine complement thyamine
Cytosine complement Guanine
i.e A-T
C-G
Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'
