Which description explains why there are two high and two low tides in a day? (4 points)
SCORPION-xisa [38]

Answer:

Earth rotates in and out of a tidal bulge twice a day.

Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.

The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Hope it helped!

The stages of mitosis were originally defined by cellular features observable through a light microscope.
Brrunno [24]

Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
