Answer:
Yes.
Explanation:
In this region we see that faulting has occurred. Because the rock strata are not lined up with one another across the entire region, it is clear that the land has faulted and the the two edge blocks have slipped downwards leaving the middle block uplifted or that the middle block has been pushed upwards.
These two types of faulting are called normal faulting and reverse faulting. They are the result of tension and compression stresses, respectively, that pull and compress the rocks creating fractures called faults. If the stress is sufficient, the outer blocks slide downward or the middle block is uplifted.
I think that the answer is c, ridges!
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 .
