Answer:

False

Explanation:

Action potential will only be fired when the memebrane potential is above the threshold level.

This follows the all-none -principle.

No matter the strenght of stimulus if the magnitride is not upto the threshold level,No action potential will.be generated.

An example is the flushing of water closet or lavoratory.No mater one tried to flush,if the water in the closet does not fill up to the threshold for flushing,,to propel flushing. not flushing will take place.

Which human body systems interact to perform temperature regulation along with the nervous and endocrine systems?
Ede4ka [16]

Answer:

Hypothalamus of human body system interact to perform temperature regulation along with nervous system and endocrine system.

Explanation:

Hypothamus is an important part of our lower brain that play a significant role in regulation of body temperature.

   Hypothalamus works with nervous system along with the other parts of our body such as blood vessels,skin and sweat gland to maintain temperature homeostasis of human body.

  When our body temperature rises at that time hypothalamus slows down the rate of metabolism of our body to restrict further increase in our body temperature and also dilates the blood vessels present beneath the skin so that body can liberate heat to the environment.

 on the other hand when the body temperature decreases at that time hypothalamus increases the metabolic rate of our body to increase the body temperature and also the constrict the blood vessels present under the skin.

Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.

Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.

Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".
