How did Koch test his hypothesis about the cause of anthrax?
Koch tested his hypothesis by isolating bacteria from the blood of animals that died from anthrax, then injecting the bacteria into healthy animals to see if they developed anthrax. He also purified the bacteria and showed that it caused anthrax when injected into animals, fulfilling Koch's postulates to demonstrate that the bacteria was the cause of anthrax.

Plants depend on animals for what substance?
Plants depend on animals for pollination, which is the transfer of pollen from the male reproductive organ of a plant to the female reproductive organ. This process is crucial for fertilization and the production of seeds, allowing plants to reproduce and propagate. Additionally, animals may also play a role in dispersing seeds, helping plants colonize new areas and increase genetic diversity.
Which substances in plants and animals cold be examined for radioactivity?
It is said that radioactivity in plants and animals, or food items, may have caused the 1986 nuclear accident in Chernobyl. In order to determine the radioactivity of these items, one could examine the DNA, carbohydrate content, H2O and other biochemical pathways that are found in all plant and animal species.

What doeshypothesis mean in sicence?
A hypothesis is an idea suggested in order to explain data (information). It's essentially the same as a theory. For example, evolution is a hypothesis that explains why different groups of plants and animals have different similarities. Once a hypothesis has been suggested, you go and collect more data that will either support the hypothesis or contradict it. In the case of evolution, DNA patterns and protein similarities support the hypothesis.
