### Subject: Psychology

What are the four major regions or lobes of the cerebral cortex, and what are each of their functions?

The 4 major lobes and their functions are as follows: Occipital Lobe: Believed to provide eye functions such as sight Temporal Lobe: Believed to provide ear functions such as hearing Frontal Lobe: Believed to function in higher level cognition and motor skills Parietal Lobe: Believed to be associated with tactile sensory information such as pain and pressure

What makes oxygen so important in the function of energy creation in cells.

Oxygen is important because it allows for the anaerobic respiration pathway to be utilized, whereas a lack of oxygen would result in the anaerobic respiration pathway taking place. aerobic respiration goes through a three step process, glycolysis followed by the Kreb's cycle, and finally the electron transport. The latter two processes require oxygen to happen, while glycolysis can happen without oxygen present. These processes allow for the production of approximately 32 atp, which is a unit of energy, with the krebs cycle and the electron transport creating approximately 28-30 atp out of that 32 total created. When anaerobic respiration takes place, only glycolysis can be performed. This process only creates 2 atp per cycle. So oxygen is important for our body's creation of energy because it allows for the krebs cycle and electron chain to happen, which creates far more atp than the glycolylis process that does not require oxygen to happen

y=6x+8 x=4y+10 Solve for each of the variables.

To solve for this equation you will plug one of the equations into the other. We see that x is equivalent to 4y+10. We can then plug that into the x in the first equation. This gives us: y=6(4y+10)+8. We then multiply both 4y and 20 by 6, since they are both included within the parentheses. We then get y=24y+60+8. We can go ahead and add the 120 and the 8 to get 128. So now we have y=24y+688. we then subtract 24y from both sides. You can think of this as 1y-24y if this makes it easier to visualize. And the result of 1y-24y is -23y. so now we have -23y=68. We can now divide each side by 23 to see what y is equal to. as a result we have y=68/-23. 68/-23 simplified is -2.9565, so y=-2.9565,. We now have figured out that any y we see in the equation is equal to -2.9565,. Now we can plug this value into the second equation to solve for the value of x so if we plug y=-2.9565, into x=4y+10 we get x=4(-2.9565,)+10. By simplifying this we find that x=-11.826+10. We simplify this to find that x=-1.826. Now we have solved for both variables, finding that y=-2.9565 and that x=-1.826.
