<h2>
Answer: They are extra-high tides and extra-low tides.</h2>
Explanation:
Tides are periodic movements of the great masses of water on our planet as part of the gravitational attraction exerted by the moon and the sun on Earth.
In this sense, there are two very special cases: The Spring and Neap tides.
<u>Spring tides </u>
Occur when there is a full moon or new moon, which makes the <u>tides higher.</u> During these lunar phases, the Moon, the Earth and the Sun are aligned and the gravitational attraction power is greater.
<u>Neap tides </u>
Occur when the moon, the earth and the sun form a right angle (
), being the gravity attraction on the masses of water the minimum. This happens in the crescent and wanning phases.
Answer:
a) calculating the concentration at which 50% of the test organisms of a particular species die
Explanation:
Bioassays -
<u>Bioassays is an analytical method to assess the effect of marine pollutant on the organism by estimating the concentration at which 50% of the test organisms die after exposing the test organisms for a specified time.</u>
It can be done by quantitative or by qualitative experiment , or direct or indirect .
It is used to detect the biological hazards or give the quality assessment of the mixture .
It is also used for the monitoring the quality of water .
Well, Ecuador is a country filled with rainforests, which occur where it rains a lot, the western side of mountain ranges, where storms build up and stall, and it could be during el nino, which means a large abnormal amount of storms in pacific tropical areas.
