Answer:
The correct answer will be option-A.
Explanation:
During anaphase, the spindle microtubules help the segregation of the chromosomes from the center of the cell at the metaphase plate.
These microtubules get attached to the chromosomes at kinetochore which helps in pulling of the chromosomes to opposite poles. The microtubules pull apart the sister chromatids when cohesin proteins degenerate.
The chromosomes do not show jiggling movement at the metaphase plate and thus, option-A is the correct answer.
Flat bones have two thin layers of compact bone which is surrounded by a layer of spongy bone.
Females have two x chromosomes while males have one x and one y chromosome hope this helps

Answer:
The correct answer would be A. nitrate and glucose.
Auxin or Indole-3-acetic acid is a plant hormone which regulates the growth of the plants.
The biosynthesis of the auxin uses tryptophan as the precursor. Tryptophan is first converted to IPA (another amino acid) which is then converted to IAA (Indole-3-acetic acid).
Similarly, the biosynthesis of tryptophan is started from shikimic acid (cyclohexane) or anthranilate (aromatic acid).
Thus, ultimately it requires glucose and nitrogen form the production of auxin.
In addition, the given picture shows that auxin is composed of carbon, hydrogen, nitrogen, and oxygen. All the molecules required for the production of auxin can be provided by glucose and nitrate.
