Answer:
C
Explanation:
Because how would you know what the reaction rate is and how it is affected by the concentrations
The options to the question above are:
A-the population of cladophora will decrease, resulting in an increase in the trout population
B-there will be a larger decrease in the trout population, resulting in an increase in damselfy nymphs
C- increased stream volume will provide more area for the trout to reproduce, causing a large increase in the population of algae
D- the population of trout will decrease because the population of damselfly nymphs will decline
The most likely immediate effect of an increase in runoff containing cadmium on the trophic structure of the river community is that there will be a larger decrease in the trout population, resulting in an increase in damselfy nymphs
- Cadmium is known to increase in the food chain and also pile up in humans. It is often taken up in water by algae, insects, and then up the food chain to fish, where it is piled up it in their gills, liver and kidneys .
It is a very toxic heavy metal that comes into the environment through anthropogenic sources such as poor quality of surface water, marine water.
Conclusively we can therefore say that Option b is the right answer because trout is negatively affected by but not the case with damselfly.

The quality of being toxic or poisonous
Answer: The work done to lift the 2 N rock was 6 Joules.
Explanation:
Weight of the Rock = 2 Newtons
So, the force required to lift this rock will be equal to its weight or greater than its weight
Minimum force required to lift the Rock = 2 N
Displacement of the Rock when force was applied = 3 m,
Work Done: It is defined as product of force applied to the object into displacement of the object.
The work done to lift the 2 N rock was 6 Joules.
