The answer is a symbiotic relationship.
Symbiosis is an interaction between two different species. Termites live feed on dead plant materials and cellulose. But their body cannot produce enzymes responsible for cellulose degradation. Therefore, they <span>established symbiotic interactions with gut bacteria which are able to digest the fiber in the wood. Gut bacteria break down carbohydrates to the smaller units</span><span>, which are then absorbed and oxidized by the termites</span>
Hello, I figured your question was missing its options so I went online to find them. Here they are:
The process of phagocytosis involves all of the following EXCEPT
:
a. adhesion.
b. secretion of cytotoxins.
c. elimination.
d. vesicle fusion.
e. chemotaxis.
Answer:
The correct answer is: b) secretion of cytotoxins.
Explanation:
Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.
Phagocytosis consists of many steps:
- activation
- the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
- chemotaxis - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
- adhesion - the phagocyte attaches to the pathogen.
- ingestion
/vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
- elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.
<u>The</u><u> secretion of cytotoxins</u><u> is not a part of the phagocytosis, and is a process exclusive to </u><u>T cells</u><u> (leukocytes that lack the ability to phagocyte).</u>
Answer:
Open-cast mining
Explanation:
The aftermath of open cast mining are pits (called quarries) on the surface of the earth where the surface soil has been removed/ displaced to access the mineral deposits that are just close or at the surface of the earth. This type of mining results in environmental degradation because they disturb the biodiversity of the ecosystem in which the mining is taking place. Rehabilitation of the area is required after the mining has been exhausted to restore the initial environment.
Answer:
Prokaryotic cells include archaea and bacteria. They do not have membrane bound nucleus as well as most of the organelles
