<span>Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA. In DNA, however, uracil is readily produced by chemical degradation of cytosine, so having thymine as the normal base makes detection and repair of such incipient mutations more efficient.</span><span>

Gennadij [26K]
<h3><u>Answer;</u></h3>

In metaphase I, the chromosome tetrads align on metaphase plate while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.

<h3><u>Explanation;</u></h3>
  • Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes .
  • Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
  • During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.

Can small trees contribute oxygen?
il63 [147K]
Yes, because even though other trees produce more oxygen, the small trees will still produce some oxygen. On top of this there are more small trees than big trees, so even though they make less oxygen, in whole they end up making more when added together!
