Pioneer species are hardy species which are the first to colonize previously biodiverse steady-state ecosystems. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.
The answer is A.
Glucose in the sealed tube will be used up by the obligate anaerobe bacterium. This is because it is the only environment that satisfies the condition of having no air or oxygen for the organism to survive. The unsealed tube will obviously have air entering and exiting inside and therefore will not be a suitable environment for the organism. The control tube will have no change in color since it is uninoculated or in other words, no organism was put inside of it.
Natural Selection is the process by which the most adapted, or fittest, species survive and the least adapted, or unfit, species do not survive. An example of Natural Selection is if there are two species of birds that eat the same thing, but one of the species has a beak that makes it harder to eat the food, naturally the species that has the beak fit to eat that food will survive. The species that is not fit to eat that food will either adapt or will be unable to survive. Evolution is a species adapting to the enviornment over a period of time. There is microevolution and macroevolution.
A reverse fault occurs when compression acts on a normal fault is referred to as a true statement and is denoted as option B.
<h3>What is Reverse fault?</h3>
Thus is referred to as the reverse type of a normal fault which occurs as a result of compressional forces on rocks and other materials in the earth crust.
This type of fault usually occurs when one side of the land moves upwards while the other side stays still as a result if the forces involved and a re commonly found in convergent plate boundaries. This is therefore the reason why true was chosen as the most appropriate choice.
