Biology is the study of life! It basically includes the relationships, ecosystems & life cycles of all organisms!
They are typically a carnivore. Scavenger's clean a dead body, decomposers eat the bones and the rest, and producers are always plants! Hope this helps!

Answer:
DNA is a type of macromolecule
.
Answer:
A) one intermediate band
Explanation:
Meselson & Stahl experiment on the E.coli bacteria to identify the mechanism of replication in bacteria.
For this, they grew bacteria in a heavy isotope of the nitrogen ¹⁵N which allowed the bacteria to take ¹⁵N in their DNA. They then grew the bacteria into ¹⁴N which allowed the bacteria now to take ¹⁴N in their DNA.
When they allowed the bacterial population to replicate their genome for one generation they found that their genome contained both types of isotopes of nitrogen in their DNA through centrifugation.
Since after the centrifugation only one band was observed which contains both the form of the nitrogen, therefore, the band was called intermediate band with intermediate density.
Thus, Option-A is the correct answer.
movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition.
