Answer:
An allergic reaction
Explanation:
An allergic reaction occurs when our immune system misinterprets a harmless substance into a harmful antigen and initiate an over-expressed immune response against it. Some of these allergic substances are pollen, molds, insect stings, etc.
These allergens trigger the production of IgE antibodies in the body which interact with different cell and initiate the release of chemicals like histamine that cause symptoms of allergic reaction.
It can affect the nose, skin, lung, stomach lining, etc. Therefore the correct answer is an allergic reaction.
Hello!
Natural selection is the way that animals evolve.
The theory of natural selection is that the animals that do not have a specific trait to survive in their environment will die. The animals that do have the trait will survive. The animals that survive will then pass the trait down to their offspring, who will also likely survive because they have the trait. This is how species evolve and continue to survive in their environment.
The species evolve because only the fittest survive (this is known as "survival of the fittest"). The animals that do not have the needed traits will die and they cannot have offspring.
I hope this helps answer your question! Have a great day!
Answer:
True The human body contains 8-10 liters of blood.
I'm not sure if it's the "best" example but.
If your blood tempature is low, the hypothalamus will issues reflex commands that make your body shiver. If you are hot, you will sweat is the opposite of this.
Another example is, if your blood contains pyrokines then you might have an infection so you begin to run a fever as your body's way to kill the pathogen at the direction of the hypothalamus.
Hope these examples help!
