True millions of different species live on coral reefs
Explanation:
Each step in a food chain or web is called a trophic level
The choices can be found elsewhere and as follows:
A. mature leaves
B. shoot apical meristem
C. cell elongation zone
<span>D. axillary buds
</span>
I think the correct answers are option B and D. It would be at the shoot apical meristem and the axillary buds that <span> a vascular plant would you expect to find totipotent cells. Hope this answers the question.</span>
The Hershey–Chase experiment was based on a bacteriophage T2 (a virus), to that DNA is the genetic material. Bacteriophage T2 attacks bacterium and makes its copies. Based on the experiment, Hershey and Chase deduced that it is the DNA of virus enters bacteria to make virus copies. To trace viral DNA, Hershey and Chase label DNA with ³²P (radioisotope of phosphorus) because phosphorus is not present in most of the proteins.
