Answer:

Nervous system:

The nervous system is comprised of two main systems, which are the Central nervous system,CNS(Brain and spinal cord) and the peripheral nervous system,(PNS).

Basic Unit:

The basic structural and functional unit of the nervous system is the neuron.

Explanation:

Frequency of the stimulus and number of receptors in the area:

As the reaction shown by the nervous system towards the change will be all based upon the number of receptors which receives the stimulus and also depends upon the frequency of the change occurred.

Cutaneous receptors:

Inside the human body there are number of pain receptors, along with which a limited number of neurons are there to receive the stimulus relating pressure,cold and warmth. As there are sensory neurons found inside the epidermis layer of the skin which are refereed to as the cutaneous receptors. They receive different stimuli, which are basically the change occurred inside or outside the organisms body.

Now, these receptors will detect any change and will direct the muscle spindle fiber either to contract or relax according to the frequency of the stimulus.

Predict what will happen to interest rates and output if a stock market crash causes autonomous consumer expenditure to fall

sineoko [7]

Answer:

Lower interest rates.

Explanation:

if a stock market crashes, the interest rates will also be lowered because they have a direct relationship between stock market and interest rates. When the stock market performs very good, the interest rates will be higher while on the other hand, if a stock market crashes, the interest rates will be lower so we can conclude that the interest rates will be lower if stock market crashes.

Describe how lymph nodes and organs help the immune system fight pathogens.

I am Lyosha [343]

The defense system of the human body is made up of entire organs and vessel systems like the lymph vessels, but also of individual cells and proteins. The inner and outer surfaces of the body are the first barriers against pathogens (germs). These surfaces include the skin and all mucous membranes, which form a kind of mechanical protective wall.

Several things support this protective wall:

- The body’s own antibacterial substances can disable different pathogens from the environment at an early stage. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.

- Many pathogens that are breathed in get stuck to mucus in the bronchi and are then moved out of the airways by hair-like structures called cilia.

- Most pathogens that enter the body together with food are usually stopped by stomach acid.

- Normal flora, harmless bacteria that reside on the skin and many mucous membranes in the body, also help to protect the body.

The cough and sneeze reflex can also help to remove pathogens.

Hope this helps (:
