Answer:
d. all of the above
Explanation:
The bats are the only mammals that have managed to perfect flight. They have managed to develop wings, but have started to have a nocturnal life, so in order to be more effective, they have developed their senses like the smell and hearing better, and also developed something new, echolocation. Because the eyesight was not really needed, the bats became almost blind, having very bad eyesight. The echolocation replaced their eyesight though, and it has proven as a very effective adaptation. It is an adaptation that manages to locate objects, food source, be it insects or flowering plants, as well as caves for shelter from predators and cold weather.

Predators and prey can be Carnivores, Omnivores, and Herbivores because there are many animals that eat a certain way Ex: A raccoon is a predator, but it also has the ability to digest and eat meat as it would usually eat fruits like grapes.

Koch's postulates are:
- Microorganism is found in all the infected organisms, but should not be present in healthy organisms.
- Microorganism can be isolated from an infected organism and cultured in lab.
- Lab cultured organism should cause disease in healthy person when injected.
- Microorganism needs to be isolated from the infected organism in step 3, the infected organism and the isolated microorganism should be checked with the case in step 1 and 2.
Some individuals contain alternate versions of specific genes (alleles) that make them resistant to particular diseases. for example, people with certain globin alleles are resistant to malaria, and some people cannot be infected with HIV because, genetically, they lack the co-receptors that the virus needs to enter cells. This will lead to the failure of Koch's 3rd postulate.
