The cell cycle represents the coordinated sequence of events in the life of a cell from its formation to its division into two d
Fofino [41]

Answer:

<h2>Interphase : divided into three phases, i) G1 phase, ii) S phase and iii) G2 phase.</h2><h2>Mitotic phase: i) prophase, ii) metaphase, iii) anaphase and v) telophase.</h2>

Explanation:

interphase : divided into three phases, i) G1 phase, ii) S phase and iii) G2 phase.

G1 phase: cell decide whether to divide or not and prepare itself for replication of DNA and arrange replication machinery.  otherwise it goes to G 0 phase.

S phase: DNA replication occurs in this phase.

G2 phase: cell duplicates all their contents and prepares for mitotic phase.

Mitotic phase:

i) prophase- chromosome condensation occurs,

ii) metaphase - chromosome arranges in meta-plate and spindle binds to each chromosomes  at centromere.

iii) anaphase- chromosome separates from sister chromatids.

iv) telophase- chromosome moves to each ends and formation of nuclear membrane begins.

cytokinesis:  there is division of cytoplasm and forming two daughter cells.

Chen draws a diagram to show water changing from a liquid to water vapor. Complete the sentences. _______All the water molecules
romanna [79]

kinetic energy is needed by the molecules in order to escape from the surface.

All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.

Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

What factors drive the movements of global air masses
maksim [4K]

Answer:

The 4 types of air masses are polar, tropical, continental and maritime. Their classification depends on their location where they are formed.

Explanation:

One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. The jet stream wind is often referred to as a steering wind. The troughs and ridges of the jet stream will help transport cold air toward lower latitudes and warm air toward high latitudes.
