What holds the two strands of DNA molecules to each other. Hydrogen Bonds
The biggest reason for that her work is a success is because new ideas often develop from unsuccessful experimentation.
The scientific process not only relies on proper experimental methods and determination, but it also is dependent on the failures of the experiments of scientists. When experiments fail, other scientists obtain a guideline of what to do and what not do. This improves their own experiments and helps them move forward.
Answer:
The correct labels are :
Label A prophase
Label B metaphase
Label C anaphase
label D telophase
Explanation:
Mitosis, a method of cell division which complete in four different phases. These phases are prophase, metaphase, anaphase and telophase. In the given question the correct labels are: A-prophase; B-metaphase; C-anaphase and D-telophase. Mitotic division is begins with prophase in which chromatin threads condense and called chromosomes. During metaphase all the chromosomes get arranged in the central plane. In the anaphase, the sister chromatids of each chromosome gets separated and move to the opposite pole. In the telophase the spindle breaks from the chromatids and begins to disappear. The nuclear membrane starts to form around each of the daughter chromosomes.
Answer:
The commercial application of ethylene gas are as follows:
The ethylene gas are important for the early ripening of fruits.
The elongation of shoot can be done by ethylene gas.
The flower stimulation and swelling of stem can be achieved by the use of ethylene gas.
The leaf abscission of ornamental plants can be done by the use of ethylene hormone.
