The cerebral cortex plays a major role in all of the following except d. circadian rhythm
The cerebrum is split into the left and right hemispheres, while the cerebral cortex makes up the outer layer of the brain and is comprised of gray matter. Gray matter is made up of unmyelinated neurons.
The cerebral cortex is described as having motor, sensory and association areas, and is involved in thought, memory, perception, awareness, and language. Overall, it is associated with voluntary movement, thus the circadian rhythm, involved in homeostasis and the autonomic nervous system, is unrelated to its function.

Answer:
B (active transport using ATP)
Explanation:
Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.
In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).
An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.
Answer:
1. primary cause of human-created carbon emissions = burning fossil fuels
2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation
3. emits methane from decomposing matter = waste disposal in landfills
Explanation:
1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>
2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.
3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.
1) is right option. The fossils are an extinct specie of elephants, and they're related to present day elephants.
