Which of the following is specific to the central nervous system?
Integration
Which of the following systems includes all the others?
Peripheral nervous system
While sitting quietly watching television, you suddenly hear the sound of glass breaking. Which of the
following is responsible for your resulting rapid heartbeat?
Sympathetic division of the autonomous nervous system
What is the general distribution of grey vs white matter in the nervous system. What are the advantages of
white matter?
Grey matter is present in the edges of the brain and the internal part of the spinal cord, and white matter is
present in the interior of the brain and the external part of the spinal cord. White matter includes axons that
have insulation with myelin, and makes transmission of signals faster.
One of the functions of the __________ is monitoring breathing centers in the medulla.
Pons
What is the function of the corpus callosum?
The function of the corpus callosum is to connect the left and right hemisphere in the brain.
What is brain lateralization?
Cerebral lateralization refers to the distribution of functions between the right and the left side of the brain,
meaning that the right and left side of the brain perform different functions.
What is referred to as climate change? What are some of the drivers of climate change? Mention three
Climate change as the name suggests indicates that the climate is changing, however the current change is
due to anthropogenic activities. Additionally, the change is happening at a fast rate which makes it harder for
many species to adapt.
Some of the drivers include an increment in greenhouse gases such as methane and carbon dioxide, which
causes the temperature in the planet’s atmosphere increases. This increment also affects the ocean; thus, the
average temperature of the ocean has increased in the past decades.
Examples: increase in extinction rates, change in species distribution, sea level rise, more severe storms,
hotter temperatures, increase drought or intense rain, melting of glaciers, etc.
Which of the following is not an abiotic factor organisms could come into contact with?
bacteria
Which of the following is the most direct threat to biodiversity:
habitat destruction
Which of the following actions could help reduce the rate of global warming?
Reducing the use of fossil fuels
Which of the following best describes the viewpoint of the vast majority of scientific studies regarding climate
change?
) Climate change is occurring and it is primarily caused by anthropogenic (human) factors
The main reason polar regions are cooler than the equator is that _____
solar radiation strikes the poles at a lower angle and travels through more atmosphere
