The network of neurons which gets activated in the condition of stress that is fear or anger is known as Sympathetic nervous system.
During stress conditions, this system prepares the body physically and mentally either to fight or flight by controlling the production of hormones through activation of specific neuron network in the body. Mainly the adrenaline and norepinephrine which act and produces the response like increased heartbeat, sweating and other.

This is because the leaf would not have tiny oxygen bubbles spread across its base (because the base is where most stomata are) that would help it float on the water. The reason is that the oxygen produced in the process of photosynthesis would be consumed in respiration because the rates of the two biochemical processes are the same.
<u>Answer:</u>
Jena is reading about the elevation.
<u>Explanation:</u>
- Elevation is the altitude (height) above the sea level. The Florida being at the height of less than 100 feet is its elevation.
- The major factor that affects the climate of that region is its elevation.as the elevation increases i.e. the height of the place from sea level increases the temperature of that place lowers.
- For every 1 kilometer rise in elevation the temperature decreases by 6.5 degree Celsius. Hence, Jena is concerned about the elevation.
Answer:
The students with the purple shirts are moving through the gym doors most often.
Explanation:
- The students with the purple shirts represent potassium ions
- Potassium ions move freely across the membrane by passive transport and are important in maintaining membrane potentials
- The movement of sodium ions is through active transport therefore this is a process that requires energy (ATP) and thus these ions are less likely to move across the membrane often
