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

aughter cells. Most of the key events of the cell cycle are restricted to a specific time within the cycle.In this exercise, you will identify when various events occur during the cell cycle. Recall that interphase consists of the G1, S, and G2 subphases, and that the M phase consists of mitosis and cytokinesis.a. non-dividing cells exit cell cycleb. at this point, cell commits to go through the cyclec. DNA replicated. centrosome replicatese. mitotic spindle begins to formf. cell divides, forming two daughter cells

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.

False.

All sources of pollution do not come from human activities.

<h3>What are the causes of pollution?</h3>

There are some natural causes of pollution. When dangerous pollutants enter the air as gases, liquids, or solids, air pollution is formed. Although there are some natural processes that can produce air pollution, such as sulfur and chlorine gases from volcanic activity, smoke and ash from wildfires, dust storms, and biological degradation, manmade sources account for the majority of pollution in the atmosphere.

Burning fossil fuels for transportation, energy, and industry produces the majority of air pollution that is caused by humans. Carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and particulates are typical pollutants released by fossil fuel-burning engines. In addition to particles, carbon monoxide and carbon dioxide are produced by stoves, incinerators, and open burning.

What is cellular respiration
Oduvanchick [21]
Cellular respiration happens in all eukaryotic cells and it occurs in the mitochondria, the powerhouse of the cell. cell resp breaks up glucose in order to create more ATP for the cell. the products that go IN are GLUCOSE and OXYGEN. the products that come OUT are CARBON DIOXIDE, WATER, and of course, ENERGY.

stellarik [79]

Answer:

The correct answer is - speciation is sympatric.

Explanation:

Sympatric speciation is a process of speciation that takes place when there is reproductive isolation between two populations of a species without any geographical separation.

This speciation takes place in the population with come ancestors as given in the question both pods of dolphins lose their ability to interbreed due to the sympatric speciation without any geographical separation.

Thus, the correct answer is - speciation is sympatric.
