Based on your understanding of the hydrologic cycle and oceans, pick the correct statement from the choices below.
IceJOKER [234]

Answer:

Neither A nor B is correct

Explanation:

Hydrologic cycle is the sequence of different conditions through which the water passes from oceans to clouds, precipitates as rains, comes to the rivers and finally reaches the ocean.

This first statement in the question said that water will end up in the river which is not true because water from the river ultimately ends in the oceans because all the rivers terminate in the oceans finally.

The second statement is also wrong because when water from one ocean vaporizes and becomes cloud, it can travel large distances as clouds in the effect of wind and thus may get precipitated in the form of rain in some other part of the world. So, it is not necessary that the water will end up in the same ocean.

What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chrom
Damm [24]

Answer:

Mitotic phase

Explanation:

Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:

  • G1 (gap 1 phase)-the cell grows and becomes larger
  • S phase- replication of DNA, duplication of centrosomes
  • G2 (gap 2 phase)-proteins and oranelles are made

Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:

  • prophase-condensation of chromatin into chromosomes,  the nuclear envelope breaks down, mitotic spindle formation
  • metaphase-the chromosmes line up (metaphase plate)
  • anaphase-the siste chromatides move toward opposite cell poles
  • telophase-the nuclear envelope forms again, cell division is almost complete
