Sympathetic nervous system is activated in this situation.

This branch of nervous system is activated when any individual encounters stressful or dangerous situation.This is responsible for 'fight or flight' response.

It takes place by activating adrenal gland which releases specific hormones adrenaline and nor adrenaline also called as catecholamines . These hormones are responsible for the appropriate physiological response to the situation.

Exercise
Goryan [66]

I just took the test this would be the correct answer.  

 

In the Precipitation Map of Washington, the dark orange section indicates low rainfall in the region. Using the Shaded Relief Map of Washington, you can tell that this area is flat, possibly a plain. These regions typically don't receive a lot of rain. The Precipitation Map of Washington has areas that are dark purple and dark green. This indicates that they both receive a lot of rainfall every year. If you look at these areas on the Shaded Relief Map of Washington, you can tell that these areas with a lot of rainfall are mountainous.  

On the Precipitation Map of Washington, purple/blue means more rain, and orange/red means less rain. The Shaded Relief Map of Washington shows mountains (brown), valleys, plateaus, and canyons. Areas that are flat are smooth on the map. Areas with steep slopes and mountains look rougher.

Explanation: This was on my feedback from the test as possible answers.

What are the demerits of cell theory?
Luda [366]

Explanation:

1.Structure of virus- Schleiden and Schwann could not explain the structure and functioning of virus cell. They said that the function of body is coordinated function of cell which is not true in the case of virus because it only starts it's functioning when hosted by bacterial, plant or animal cell.

2.Prokaryotic cells- The cell theory do not holds true in the case of Pk cells because they do not have any well defined nucleus.

3.Multinucleate condition- The cell theory says that each cell have A NUCLEUS, but there are certain cells like tapetal cells that are coenocytic.

4.Cells without nucleus- Acc to cell theory there should be a nucleus in every cell, but human RBCs, sieve tubes of angiosperm are some of the cells lacking nucleus.

Aerobic respiration creates lactic acid as a by prodcut but prodcues far more atp than respiration.
Nonamiya [84]

False, aerobic respiration creates lactic acid as a by product but produces far more ATP than respiration. When lactic acid is ferment by certain bacteria which includes the bacteria in yogurt and also by human muscles cells when they are worked hard and fast.

In aerobic cell respiration which includes glycolysis + the kerbers cycle = respiratory electron transport that produce 36 ATP /glucose consumed. Aerobic respiration cell are 18 times more efficient than anaerobic cell respiration because in aerobic respiration more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water .

Now O2 acts as terminal electron accept in this electron transport chain and gets reduced to water.ATP are produced by oxidation phosphorylation in the electron transport chain.
