<span> The hypothesis is an idea that suggests how things work in nature.
The main way the hypothesis is going to help you is by testing it,
scientists can (most of the time) set up tests to verify is the
hypothesis is possible or not, still that doesn't mean that the
hypothesis is true. If the hypothesis is possible(likely to be right)
and is the more likely to happen, it is said to be an accepted
hypothesis. Hope this helps!!</span>
You can test the different between using less eggshells and more eggshells and record the data to see which one works better
Answer:
The correct answer is A) DNA passed from the heat-killed strain to the living strain.
Explanation:
Griffith's in 1928 showed that a virulent strain of heat-killed bacteria when mix with a non-virulent strain of bacteria then the non-virulent bacteria transforms into virulent bacteria. Later it was proved that DNA was the material that transfers from virulent strain to non-virulent strain and transform it into virulent strain.
So as DNA is the genetic material that passes from one generation to another and one bacteria to another not protein therefore after mixing a heat-killed phosphorescent strain of bacteria with non-phosphorescent living strain, DNA must be passed to living strain from heat-killed strain to gain phosphorescent ability.
Therefore the right is A) DNA passed from the heat-killed strain to the living strain.
Answer:
A .Viruses cannot evolve but can infect living cells.
