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>

Answer:
Africa appears much bigger than the other landmasses on the Peters map projection.
Explanation:
There are numerous projection maps. All of them have some advantages and some disadvantages. One of those map projections in the Peters map projection or Gal-Peters map projection. This map projection's biggest problem is that it stretches certain parts of the world, some horizontally, some vertically.
On this map projection, Africa looks much bigger than it is, and it is comparable with the size of Asia even though Asia is much bigger in reality. The reason for this is that on the Peters map projection a vertical stretching occurrs around the Equator, and since the Equator passes around the middle of Africa the effect is the biggest at this landmass.
