Answer;
-Association areas
The association areas of the cerebral cortex are not involved in primary motor or sensory functions; rather, they are involved in learning, remembering, thinking, and speaking.
Explanation;
-The cerebral cortex is divided into sensory, motor and association areas. Sensory areas receive and interpret impulses from sensory receptors , motor areas control movement of muscles (initiate impulses to skeletal muscles). Association areas are involved with more complex functions such as learning, decision making and complex movements such as writing.
-Association cortex is the cerebral cortex outside the primary areas, The majority of the cortex is composed of this area. It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation.
Answer:
B. Early Eukaryotic cells engulfed mitochondria and chloroplasts
Explanation:
Mitochondria and Chloroplast are organelle that are found in cells of higher animals. Chloroplast are found almost exclusively in plants and mitochondria is found in animal cells. The function of these organelles are to produce energy to the cells, and by extension, the organism that they live in.
Unique features of these organelles show that they have their own DNA and divide and multiply on their own. This strongly suggest that they were once free living prokaryotes and were engulfed by larger cells and a symbiotic relationship began.
As time progressed, these prokaryotes did not require all of their genetic information and this was removed from their system. They kept essential genes and regulatory bodies separate that they needed for their maintenance and function that they provide.
<span>All of the answer choices relate a source of pollution with its effect; however, all of them except one is correct. <u>The answer is B.</u>
Option A states that the use of aerosol sprays increases ozone; however, the effect is the opposite. Moreover, the depletion does not result in acid rain. In option C, although fossil fuels do cause air pollution, they do not do so by reducing the water vapor content. Instead, they actually increase water vapor content. Their effect is of increasing the content of carbon dioxide, sulfur dioxide and nitrogen dioxide. Finally, CFCs cause ozone depletion, they do not seep into the ground.</span>
