English Translation:
V: Virus, is a very small organism, which does not have the capacity to reproduce itself. This particular virus reproduces only by invading human cells, it does not affect animals. HIV is a fragile virus that cannot survive outside the body.
I: Immunodeficiency, because the effect of this virus is to create a deficiency in the proper functioning of the body's immune system. It infects and destroys immune cells, called T4, to grow and reproduce. It causes the organism to be defenseless, this situation is used by various infections and cancers to attack the organism and cause its death. These diseases are called "opportunists," because they take advantage of the weakness of the immune system to attack. Over time the virus weakens the person's defenses against the disease, leaving him vulnerable to many infections and forms of cancer that would not develop in healthy people.
H: Human, because the virus can only be contracted by humans. In the animal kingdom there are viruses with similar characteristics in apes and felines. It is believed to come from a specific type of African monkey.
HIV belongs to retroviruses. HIV can only replicate inside the cells, ordering the reproduction to the machinery of the cell. It belongs to the family of retroviruses, which means that it is able to reverse the direction of the information that normally flows from DNA to RNA, but in this case it does it in the opposite direction thanks to the reverse transcriptase, thus introducing its genetic code and through the integrase it "integrates" the code of the infected CD4 cell, which allows it instead of multiplying, what it does is produce new viruses, called virions.
HIV is a lentivirus. HIV belongs to a subset of retroviruses called lentiviruses, or "slow" viruses. The course of infection by these viruses is characterized by a prolonged period between the initial infection and the appearance of severe symptoms. It is known that from the moment of the initial infection it reproduces constantly, mainly in the lymphatic system.
Typhoid fever is a bacterial infection that affects the intestine and occasionally the bloodstream. The germ that causes typhoid is a variety of salmonella, called Salmonella typhi. The disease can be contracted by anyone, but the greatest risk is that of people who visit countries where the disease is common.
Answer: Bacteria

Answer:
Sulfur trioxide is a covalent compound. Which is the chemical formula for sulfur trioxide? A. SO3 B. (SO)3 C. S3O D. S3O3
Explanation:
Sulfur trioxide = SO3, is a chemical class that, however, is composed of sulfur and oxygen atoms.
The answer is: A. SO3.
B.Plankton dying due to pollution
C.Fish moving to cleaner water
D.Birds migrating to a warmer climate
The outcome of a seasonal change meaning a change that happens over and over at a certain time of year is Birds migrating to a warmer climate.
The earth's rotate at its axis is tilted with regards to its orbital plane which leads is to different seasons.
When the earth's axis is towards the sun, it's summer in that hemisphere. When the earth's axis points away, vice versa.
Thus, option "D" is correct, Birds migrating to a warmer climate.
