Answer:
A way to answer scientific questions
Explanation:
AP3X
is the step in science when you do an experiement
1. Make a question
2. background research
3. create a hypothesis
4. test/experiement
5. analyse
6. conclusion
7. share - because when you share it to others, others can repeat your experiment and prove is it true or false or is it really science
Whitecap and swell are the two types of waves which are generated by moving over of water.
Waves are normally generated by the wind moving over water surface. They indicate the speed of the wind in the area. Swell is the wave which usually with smooth tops and that have moved beyond the area where they were first generated.
Height of waves varies over time. The wave height is calculated statistically as the average height of the highest one-third of the waves that is experienced over time. Swell waves are the regular, longer period waves which are generated by distant weather systems. They may travel over thousands of kilometers distance. A whitecap is a wave formed when the narrow crests of a wave are blown off by the winds. This creates a mixture of air and water.

make inferences regarding changes in populations of species. Which of the following would be
an inference based on observations?
There must be some sort of battle for existence since more people are generated than can be sustained.
Darwin and Alfred Russel Wallace, one of his scientific contemporaries, claimed that natural selection, or evolution, is the result of this process.
According to the principle of natural selection, organisms breed younger than they can withstand in their surroundings. Those who are more physically capable of surviving, maturing, and reproducing. On the other hand, those that lack this fitness either do not live long enough to reproduce or have fewer children than their counterparts. Because the "fittest" organisms—those most adapted to their environment—are the ones that reproduce most effectively and are most likely to pass on their qualities to the next generation, natural selection is frequently summed up as "survival of the fittest."
This implies that if conditions change, qualities that help people survive in it will eventuallyadapt, or develop. Naturalselection was able to describe the evolution of life with such force that it was accepted as a scientifichypothesis. Since then, biologists have seen several instances of how natural selection affects evolution. It is now understood to be one of several ways via which life develops. For instance, the phenomena of genetic drift can potentially lead to the evolution of species. In cases of genetic drift, some species unexpectedly generate more offspring. Even if those creatures may not be the best of their species, the genes they contain are passed on to the following generation.
Therefore, the idea of the battle for existence was the thought put forth by Darwin.

Answer: Since more individuals are produced than can be supported, there must be some type of struggle for survival.
Explanation: Hope it helps :)
Answer:
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.
