Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).

Griffith experiment
Griffith used two types of bacteria in his experiment
1. R-type: it was non-virulent and cause no disease in mice
2. S-type: It was virulent and cause disease in mice which lead to death.
However when heat killed S-type was applied no disease was occurred in mice. Then he mixed heat killed S-type and live R-type and injected it into mice. He was expecting that no disease will be caused in mice.
Results
However, mice was died.
Conclusion
He was confused from this experiment. But later it was confirmed by other scientists that DNA from heat killed S-type was shifted to R-type. the progeny which formed from this transfer of DNA were virulent and cause the death of mice.
significance
It was concluded from this experiment that DNA is a hereditary material which transfer characters from parents to offspring.
Answer:
The sceintific law explains the behavior of natural phenomena.
Explanation:
There are thousands of bacterial species and they are not identical towards one another, therefore there forms are quite unique. so its just there characteristics that make up how bacteria look like.
Hope this answers your question.
