This is kind of hard to show without the picture, but to make an ionic bond with Na and Fl you would have the sodium move an electron to the fluorine, so the answer is C! This is because of the fact that sodium has an outer shell valance electron (so it's unstable) and the fluorine would accept that because it is missing an electron in the outer shell. So this sharing would lead to the bond being created!
Answer - A. From a N.A code to an A.A code.
Reason - The DNA sent a instructions aka nucleic acid (code) to make amino acid which is important for our muscles.
The answer is <span>Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.</span>
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
<span>In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.</span>
The first statement describes the environmental factor that affected the skipper butterflies.
When the birds became involved in the skipper butterflies ecosystem, they became a biotic environmental factor. The other answer choices are not environmental factors, but they are adaptations and examples of survival of the fittest.
Hope this helps! Good luck! :)
En las arqueas, generalmente se encuentra en la forma L-isomérica, mientras que las bacterias y eucariotas tienen la forma D-isomérica. Una segunda diferencia es la presencia de un enlace éter en oposición a los lípidos enlazados a éster que se encuentran en eubacterias y eucariotas.
