Explanation:
The Theory of evolution suggests that the organism has evolved from a common ancestor that is "Descent with modification".
In the given question, the new fossil was found and the anatomical structures were compared with that of Horses and the Sloth.
The similarities in these three species show that they were evolved from the common ancestor but the differences in the number of teeth and bones in toes with the sloth show that the fossil and the sloth are not closely related.
The new fossil is more closely related to the horses because the three anatomical traits are more similar to the anatomical traits of the horses. This could show that the species are more closely related.
Answer:
1796
Explanation:
Proclaimed Inventor: A country doctor by the name of Edward Jenner, living in Gloucestershire, England, performed the first vaccination in 1796. These vaccinations by Edward Jenner were made to prevent cowpox and smallpox.
Short note on vaccination: Vaccines work like this: Vaccines contain antigens that our body produces antibodies to attack. Basically, the vaccine contains a variation of the same stuff the virus you're wanting to prevent is made up of so that when the real antigens try to enter your body and wreck havoc, the body will have obtained a mechanism to fight it off.
How can we prevent airborne and waterborne diseases?: Well, you can't necessarily prevent the spread of an airborne or waterborne disease, but if you'd like to avoid it, consider avoiding contact with others, staying home when sick, wearing a face mask in public, and covering your mouth when you cough and sneeze. As for waterborne diseases, the best a human can do is to practice good personal hygiene and drink properly filtered (purified) water.
So, airborne=limited contact, and waterborne=proper care of self and water.
