Explanation:
Lanark proposed a theory of evolution hinged on use and disuse of body parts. This is a theory that upholds the transfer of acquired traits to offsprings. Darwin's theory of evolution was rather based on natural selection or 'survival of the fittest'. Darwin's theory has more evidence backing it compared to Lamarck's theory. The field of genetics which appeared long after Darwin's death confirmed that inherited traits are indeed passed from parents to offsprings. These inherited traits are usually those that give organisms an edge over others in their environment.
Earthworms are brown and not green or beige because, the brown earthworms have the same colour as the soil and are better enabled to escape from predators. From Darwin's theory, the brown earthworms are the 'fittest' hence they survive in their environment. Lamarck's theory may approach the matter from the point that earthworms move with their bodies on the soil more frequently, hence they 'acquired' the brown colour and passed it on to their offspring.
From the activity, "Hiding in the Background", individual worms spent their entire life cycle in either green or beige colour. Their colour didn't change as a result of the environment where they lived, rather the green earthworms were more in number, not particularly because of any specific changes the earthworms themselves had undergone, but because most of their predators concentrated on eating the beige worms. As a result of this, there were many green worms when the next generation began compared to the number of beige worms. Hence, there were more green earthworms.
The 8-Step Problem Solving Process is vital to solving problems in an organized way and it's an extended form of OODA Loop. Therefore, it's logically true.
The 8-Step Problem Solving Process include the following:
- Defining the problem.
- Clarifying the problem.
- Defining the goals.
- Identification of the root cause of the problem.
- Development of an action plan.
- Executing action plan.
It should be noted that the 8-Step Problem Solving Process was developed as an intended expansion of the OODA Loop. Therefore, the statement is true.

Sand and salt are poured into a single beaker. the result is a mixture because they are not chemically combined. When water is added to the sand-salt mixture, salt dissolves in water, and sand does not. When the liquid is poured through a filter, salt water passes through the filter. The remaining salt water is heated until water is boiled off (evaporated) leaving salt behind.
The answer is C, Extinction.
If there was no diversity then a single sickness could wipe out a whole population, but if the population was more varied theres a higher chance someone is more resistant to the sickness and could carry on the species life
