Mrrafil [7]

Answer:

interphase

Explanation:

Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.

There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include  cell grows, DNA replicates and prepare itself for mitosis.

Hence, the answer is "interphase".

A frog with a mass of 0.29kg hops up in the air. At the highest point in the hop, the frog has a gravitational potential energy
PtichkaEL [24]

Answer:

0.27m

Explanation:

To get the energy

Potential energy= Mgh

M is Mass

G is acceleration due to gravity

H is height..

M= 0.29kg, h= ?

P=0.759. g=9.8m/s

Therefore,

0.759=0.29×9.8×h

H= 0.759÷2.842

H= 0.27m

ad-work [718]

Mitotic division in onion root cells:

  1. Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
  2. Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
  3. Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
  4. Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
