The use of the isotope 32P as a tracer element in the study of invasion and lysis of bacteria by viruses has shown that bacteriophage protein enters the bacteria.
Phosphorus-32 is a radioactive isotope of phosphorus, such that the nucleus of phosphorous-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorous, phosphorous-31.
As the individual body size of an organism increases, the population density for this organism in a given habitat tends to decrease.
<span>It has been shown that an inverse relationship between the size of an animal and its local abundance exist. Animals with larger body size have higher energetic requirements, resource exploitation, and susceptibility to predation and thus the competition is bigger. Yet, the density–body size relation depends on the physical complexity of the habitat and population of a species.</span>
Answer:
Phoebus Levene
Explanation:
Since he performed hydrolysis experiments on nucleic acid. He also discovered that DNA is composed as a series of monomers called nucleotide.
