Answer:
Prophase I
Explanation:
Meiosis is the cellular division that produces the gametes and results in 4 haploid cells. Since these cells will go on to become the offspring, it's important for genetic variation.
Crossing-over is one contribution of genetic variation because it is where the homologous chromosomes exchange parts of their genes. In meiosis, it occurs in Prophase I.
Hope this helps!
Answer:
The correct representation is attached with the explanation.
Explanation:
In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
