Answer:
1) Binds soil particles into aggregates and improves the water holding capacity of soil.
2) When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
3) Carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming.
Without greenhouse gases in its atmosphere , the Earth would be much colder on average than it is now. Greenhouse gases: absorb energy transferred as infrared radiation from the Earth's surface. release infrared radiation in all directions, which keeps the Earth warm.

Answer:
Parasitism.
Explanation:
Parasitism is an association in which one organism, lives on another, the host, deriving benefit from it and causing harm to it.
The tapeworm here is a parasite and it lives inside the cat's(host) body where the tapeworm is specialized for its mode of life. It survive and reproduces very well without needing another specie because it is a hermaphrodite. It causes loss or poor development of unwanted organs such as the digestive, sense organs and muscles. Its long flattened body also provides a large surface area for absorption of nutrients too.

Explanation:
Answer:
The correct answer is "two examples of how radar installations might cause hazard to human health are: decreased ability to perform mental tasks and induction of eye cataracts".
Explanation:
According to the World Health Organization electromagnetic fields below 10 Gigahertz of power do not represent a threat to human health, which make most radar installations safe for operation. However, some studies performed in primates by the exposure of increasing levels of electromagnetic fields have shown that they can developed a decreased ability to perform mental tasks and induction of eye cataracts. This is explained by the exposure of electromagnetic fields that can increase the animals' body temperature by one centigrade.
Answer:
Ethnicity
Explanation:
<em>The correct answer would be </em><em>ethnicity</em><em>.</em>
<u>By definition, ethnicity refers to the variety of physical and behavioral characteristics that distinguishes one group of people from another group of people. </u>
Individuals or a group of people that shares the same culture and a sense of identity would belong to the same ethnic group while those with dissimilar culture and physical identity would be in different ethnic group.
