Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
Answer: option C) cowpox and smallpox are caused by the same virus
Explanation:
Cowpox is a skin disease that affects cattle. It is caused by an Orthopoxvirus, with lesions occurring principally on the udder and teats of the animals.
Human infection may occur from touching infected cows, and thus giving immunity to smallpox (an acute infection caused by the same poxyvirus, in HUMANS)
So, Jenner's successful use was because cowpox and smallpox are caused by the same virus
Answer:
Convergent Evolution.
Explanation:
When two different species that are very distantly related but have similar traits its Convergent Evolution due to environmental pressures.
Kingdom is the largest division that a group of organisms can belong to, for example “animal” or “plant” is a kingdom. In order: kingdom, class, genus, species.
Example of:
Class- Mammals would be a class of the kingdom “animal”
Genus- Homo would be a genus of “mammal”
Species- Homo Sapiens
