The immune system.
The immune system acts as a defense system of the body. It fights against bacteria, viruses and any other disease causing pathogens. Some chemicals can weaken the immune system and make them vulnerable.
Answer:
Neutrophils help fight infections because they ingest microorganisms and secrete enzymes that destroy them. A neutrophil is a type of white blood cell, a type of granulocyte and a type of phagocyte.
Explanation:
Neutrophils display adhesion glycoproteins on their surface to bind endothelial and subendothelial structures. They move randomly until they find a damaged site. Unless neutrophils are activated, endothelial cells do not tend to adhere. When inflammation mediators (IL-1, FNT) activate endothelial cells, they express P-selectin and E-selectin on the surface. The expression of glycoproteins and L-selectin cause the initial adhesion of the non-stimulated neutrophil to the activated endothelium, slowing it down by rolling it over the endothelium. Activated endothelial cells, opsonized particles, immune complexes, FEC-G, FEC-GM and chemoattractants produce factors that stimulate neutrophil activation. Expressing β2 integrin (endothelium adhesion molecule) Neutrophils expand and form pseudopods. Neutrophil activation also promotes degranulation, superoxide generation, and arachidonate metabolite production.
As we already know, organism mean's something that is living.
Well, at a habitat there is going to be some animal's or insect's because it's that animal's or insect's habitat. ( They live there.) Well <u>most</u> organism's are food.
( NOTICE I bloldfaced "most", this is because not all organism's are food) Okay, let's go over what we just said. Organism's are living thing's and habitat's are places where organism's live. Now we have to think about this, you stated, Describe how is an <u>organism's food</u> and habitat related. The one thing we have not talked about is, <u>organism's food</u>. Okay, Animal's live in habitat's and so do organism's.
( Remember, some <u>organism's eat other organism's</u>) This is how organism's food and habitat are related.
<u>Hope this help's!</u>
<u>Good luck on your </u>
<u>home work! (:</u>

Homeostasis is the process by which organisms keep internal conditions relatively constant<span> despite changes in external environments. Homeostasis in the body is maintained by feedback loops.
