Answer:

Prophase I

Explanation:

In prophase I, each pair of homologous chromosomes (one chromosome from each parent) lines up side by side. This aligning of homologous chromosomes is called synapsis. At synapsis, the homologous chromosomes are held tightly together

along their lengths. While they are lined up, segments of the chromosomes may be exchanged. This process of exchange of genetic information is an important mechanism for providing genetic diversity, and is discussed later in this section. As prophase I continues, the centrosomes move to the poles of the cell and the spindle apparatus forms.

Where is the moon when you are in a location experiencing a low tide?

Citrus2011 [14]

Answer:

Explanation:

The gravity of the sun and moon pull on the water of the oceans of the earth hence causing a bulge of these waters at the point on earth where the moon is above. The region where the moon is above, and the opposite side on the earth, will therefore experience high tides while the places at right angles (on the surface of the earth in relation to the moon position) will experience low tides.
