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:
It absorbs.
Explanation:
The ocean absorbs carbon dioxide from the atmosphere wherever air meets water. Wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide. Fish and other animals in the ocean breathe oxygen and give off carbon dioxide (CO2), just like land animals.
Cells are usually what teachers teach as the “building blocks” of life.
hope that helps :)

Answer:</h2>
Generally, <u>D) non-metals are gases</u> which are at room temperature.
<h2>
Explanation:</h2>
Those metals which lack the property of the metal are called as non-metal. Usually they are characterized by the following features:
- Nonmetals don't conduct electricity through them.
- Nonmetals don't allow heat to pass through them.
- They don't show ductility and malleability.
- The nonmetals not only include gases but there are some solids which do not exhibit the above mentioned characters are also nonmetals. Some of the solid nonmetals includes graphite, carbon, wood, and so on.
Thus, from the above data, it can be inferred that option D which states that gases at room temperature is considered as most suitable answer for non-metals, as option A, B, and C are characteristic of metals.
