Answer:
B. hydrogen bond
Explanation:
The double helix is held together by hydrogen bonds between the bases
The type of bonds that are involved in these transient protein - DNA interactions include: IONIC BOND, VANDER WAAL FORCES AND HYDROGEN BOND.
Protein - DNA interaction occur when a protein bind to DNA molecule; this reaction usually occur in order to regulate the function of DNA, especially that of expression of genes. Protein interaction with DNA may be specific or non specific.
Answer:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

Answer:
The correct answer is -
A: Prophase (top left)
B: Cytokinesis (top middle)
C :Interphase (top right)
D :Telophase (bottom left)
E: Metaphase (bottom middle)
F: Anaphase (bottom right)
Explanation:
A. prophse - the first stage of mitosis, in this pahse the chromatin which is DNA and proteins, condenses in nucleus.
B. Cytokinesis - It is the physical sepration or dividion of cytoplasm of the parental cell.
C. Interphase - This phase have no change in cell except its size as it grows and enlarges itself.
D. Telophase - formation of a nuclear membrane around chromosome set to separate the genetic material from the cytoplasm.
E. Metaphase - visible chromosomes, removal of nucleus and chromosomes present in cytoplasm.
F. Anaphase - replicated chromosomes are separated and move towards opposite poles.
