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:
Polaris is most popularly known as the North star. It is also famous by the name of "Pole Star". It is the closet to the north celestial pole. At present it is the northern pole star currently.
It is found in the constellation of Ursa Minor. It is the one of the brightest star seen in the night sky. It is considered the star of the second magnitude which is situated close to the heaven's north pole.
The altitude of the Pole star or the Polaris when an observer is at the Tropic of Cancer is measured at 23.5 degree. While if the observer sees the Pole star at its zenith, the observer is located at the North Pole. i.e. 90 degree.
And the spot from where the observer views the Polaris at 45 degree altitude is Massena, New York.
Answer:
The statement that best describes the benefit of studying biology is the ability to intelligently debate issues such as cloning.
Explanation:
Biology encompasses the study of all known forms of life, including their anatomy, organization, functioning and interactions.
One of the advantages of the knowledge acquired through biology is to be able to participate in works and discussions involving subjects related to living beings, including cloning.
The other options are not correct because:
<em> a and c. The </em><u><em>ability to experiment on animals or preserve animals that are extinct</em></u><em> is reserved for scientists with a deep knowledge of biology and its fields.
</em>
<em> d. Understanding the </em><u><em>causes of wheather change</em></u><em> does not correspond to knowledge in biology</em>
<span>The human tympanic membrane or eardrum is a thin, concave membrane stretched across the inner end of the external auditory canal much like the skin covering the top of a drum. The eardrum marks the border between the outer ear and middle ear. ... The middle ear transmits sound from the outer ear to the inner ear.
Answer would be </span>
