Answer:one disadvantage is that if you do not live in a windy area you will have a hard time. if you live in a windy area then that will be of great help
Explanation:
Answer is (E) : Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Let me explain you why. Hershey and Chase conducted their experiment to show what is the genetic material that passes from one generation to another generation. Is it protein or DNA? For explaining this, they allowed the virus to grow in the presence of two different radio active elements.
In one set they grew viruses in the presence of P-32 radio-active element
In another set they grew viruses in the presence of S-35 radio active element.
The reason why they choose these two radio-active element was, phosphorus is present in DNA but not in proteins and similarly sulphur is found in proteins but not DNA.
These viruses were allowed to infect bacteria and the later was observed to be radio-actively labelled with P-32 but not S-35. This clearly showed that DNA is the genetic material which was passed from virus to bacteria.
Now if you choose Nitrogen for labeling, it won't help you in getting any conclusion since nitrogen is present in both proteins and DNA.
The correct answer of the given question above would be option C. The best option that defines sustainable fishing practices is that, harvesting practices that do not reduce the potential for future harvests. Sustainable fishing guarantees that the population of the ocean and freshwater wildlife is still present over time. Hope this answer helps.
Answer:
1. Asexual Reproduction (If there is only one organism reproducing)
2. Selective Breeding
Explanation:
1. If there is only one parent organism that means the offspring it is a carbon copy of its parent.
2. Selective breeding is breeding to bring out more desirable traits out of the species, like how dog breeders breed for better sense of smell or hearing.
Hydrogen would be the answer to this.
