What are the two theories of evolution in a eukaryotic cell?
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.
What is the sequence of events that occurs from the end of one division to the end of the next division?
cell cycle
What is genome and state what major events must occur during cell division for the entire genome to be passed on to daughter cells?
A genome is the complete set of an organism's genetic material, including all of its genes. Major events during cell division that ensure the entire genome is passed on to daughter cells include DNA replication to create identical copies of the genome, alignment and separation of chromosomes during mitosis or meiosis, and distribution of chromosomes to daughter cells during cytokinesis. Any errors in these processes can lead to genetic mutations or chromosomal abnormalities.
4 types of events that take place in a eukaryotic organism such as a deer that require cell division?
Growth: Cell division is essential for an organism like a deer to increase in size as cells multiply and tissues grow. Development: Cell division is instrumental in the development of specialized cells and tissues that enable the deer to function properly. Wound healing: Cell division plays a vital role in the repair and regeneration of tissues in response to injuries or wounds sustained by the deer. Reproduction: Cell division is necessary for the production of gametes in the reproductive organs of the deer, ensuring reproduction and the continuation of the species.
What is the correct order of events in the cell cycle?
The Sequence events of the cell cycle isinterphaseprophasemetaphaseanaphasetelophase.
What supports the idea that eukaryotic cells evolved after prokaryotic cells?
In a basic sense, eukaryotic cells are more complex than prokaryotic cells in their shape, function, differentiation and speciation. One theory that strongly supports eukaryotic evolution from prokaryotic cells is in the mitochondria. Mitochondria actually has its own DNA that is passed from generation to generation, The structure of the mitochondria is very similar to a basic prokaryotic cell, and some research has even indicated that the mito-DNA is actually similar to old bacterial DNA. This supports that perhaps at one point, a eukaryotic cell injested a bacterial cell, and instead of digesting it, the bacterium just stayed inside the euklaryotic cell and the two became one (this is a gross oversimplification, but the general idea remains the same).

What events led the temporary division of Korea?
The division of North and South Korea was the 38th Parallel before the war, during the war, and after the war.
What prompts a prokaryotic cell to stop replication and undergo cell division?
Prokaryotic cells typically stop replication and undergo cell division in response to signals indicating that nutrient availability is adequate for growth and division. Once the cell has reached a certain size and key cellular components are duplicated, it triggers a series of events that lead to cell division. The presence of certain environmental cues or changes in the cell's internal condition can also influence the timing of cell division.
What is endosymbiosis effect on evolution?
Endosymbiosis is a process where one organism resides within another, forming a mutually beneficial relationship. This process is believed to have played a significant role in the evolution of eukaryotic cells by allowing for the incorporation of prokaryotic organisms to perform specialized functions. For example, mitochondria and chloroplasts are thought to have originated from endosymbiotic events.
What is the sequence of events that occurs from the end of one division to the end of the next division?
cell cycle
What events led to the division of Europe?
The Cold War.
When does replication occur in the replication of DNA?
In Mitosis - the events that prepare the Eukaryotic Cell for division and the division process itself constitute a complex cell cycle. Interphase is the 1st phase of the cycle and is made-up of 3 phases (G1, S, & G2). It is during the S-phase (the "Synthesis" Phase), that the DNA replicates, producing 2 copies of each chromosome.
Where does most of the cells growth take place in the cell cycle?
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. In cells without a nucleus (prokaryotic), the cell cycle occurs via a process termed binary fission. In cells with a nucleus (eukaryotes), the cell cycle can be divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase the cell grows, accumulating nutrients needed for mitosis preparing it for cell division and duplicating its DNA.
What are three events that lead to speciation?
Separation, Adaptation, Division
