Answer:
In the given case, it is clear that the sympathetic part of the autonomic nervous system is on in Mr. T. It can be suggested due to the increase in heart rate and appearance of cold and pale skin in the patient's upper body. The sympathetic nervous system is the component of the ANS, which is an extensive network of neurons that monitor's the involuntary processes of the body.
Mainly, the sympathetic nervous system monitors the features of the body associated with the fight or flight response like increasing heart rate, mobilizing fat reserves, and discharging adrenaline. Apart from this, the increased heart rate and vasoconstriction will assist in elevating the patient's blood pressure.

Fossil fuels are commercially available as an energy source.
They are very easy to find. More and more extractions of fossil fuels is going on everyday. With advancement in science and technology, the refineries and extraction procedures have improved a lot. This makes their availability even better.
Fossil fuels are also easily combustible. Most combustion engines need to be powered with little amount of fuel to produce large amount of energy. Very large amounts of electricity can be generated from fossil fuels.
Answer:
The correct answer is chemical energy from broken bonds is transformed into mechanical energy.
Explanation:
Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.
The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.
Answer:
The bonds that are formed between nitrogenous bases are Hydrogen Bond.
Explanation:
When a hydrogen atom interract with an electronegative atom such oxygen,fluorine hydrogen bond forms,
A single hydrogen bond is weak noncovalent bond but collectively they exerts very strong interraction.
Hydrogen bonding occurs between complementary base pair .For exam An adenine base forms 2 hydrogen bonds with thymine base whereas guanine forms 3 hydrogen bonds with cytosine base.
The hydrogen bonding between complementary is very much important to stabilize the structure of DNA .
