Answer:
a. Fluid intelligence
Explanation:
Cattell-Horn's theory of fluid and crystallized intelligence suggests that intelligence is composed of a series of different skills that interact and work together to produce general individual intelligence.
<u>
Fluid intelligence</u> implies being able to think and reason abstractly and solve problems. This ability is considered independent of learning, experience and education. It is basically configured by primary skills such as induction, deduction, relationships and figurative classifications, breadth of associative memory and intellectual speed, among others. It reaches its maximum splendor in the early twenties and tends to decrease in parallel to the aging and deterioration of neurons. This ability can be measured from tests that measure the biological potential of the individual to learn or acquire knowledge.
Explanation:
Fossil fuels are important energy sources for our every day activities.
Formation of fossil fuels
Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.
How are they obtained
First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.
For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.
For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.
How are they used
Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.
Natural gas is used as a domestic fuel for cooking and so also coal.
When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

Answer:
Trees will compete with shrubs for light and space so by adapting for increased flammability, chaparral scrubs promote natural wildfires to eliminate their competitors. While these fires destroy the trees, the shrubs are still able to germinate afterwards.
Explanation:
Thy decompose dead organisms, and it turns into better soil.
