Answer:
Option C
Explanation:
Dr. Leland Hartwell used baker’s yeast, <em>Saccharomyces cerevisiae</em>, as a model system, which was a highly suitable model for cell cycle studies. He introduced the concept of Checkpoints where he said cells are arrested if damaged so that the cells repair system can work to correct such damages. Dr. Paul Nurse used a different type of yeast, <em>Schizosaccharomyces pombe</em>, a type of yeast distantly related to the baker's yeast as a model organism.
I think it’s A... not sure! Because you have no A so maybe A

Answer:
1. Metaphase
2. Prophase
3. Telophase
4, 5, 6, 8. Interphase
7. Anaphase
Explanation:
Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.
Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.
Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.
Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.
Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.
In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.
Answer: A, C, and E are correct
Explanation:
Sympatric speciation is a random or naturally occurring event whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e no single specie occupy
an area in isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory and practice non-random mating, which favors some genes results in an uneven gene flow or disruption of alleles previously common among the population.
- produce offspring with extra sets of chromosomes known as polyploidy, leading to show genetic variations
Finally, M. graminicola and S passerinii are Sympatric species based on the already given explanation.
