The structure that produces and organizes the proteins that form spindle fibers is most likely the metaphase because that is what pulls the fibers apart
Answer:
Bt cotton is a genetically modified organism (GMO) or genetically modified pest resistant plant cotton variety, which produces an insecticide to combat bollworm.
Darwin's proposed mechanism for evolution is natural selection. Natural selection allows species to respond to their surroundings through time, or to become progressively excellently-suited. Natural selection is environmentally based and involves established heritable variation within a population.
They lead to changes in species over time:
- Darwin suggested species will evolve over time, new species originate from pre-existing species, and all species share a common ancestor with each other.
- In this framework each organism has its own special set of heritable i.e genetic variations from the common ancestor that have slowly developed over very longer periods of time.
- Parroted branching activities that isolate new species from a common ancestor create a multi-level tree that connects all living organisms.
Answer:
Metaphase (mitosis) and metaphase I ( Meiosis)
Explanation:
In a diploid organism, the chromosomes are present in pair called homologous pair which has to be distributed in the cells during the cell division cycle.
The distribution of the chromosomes in a cell is observed in four subphases: prophase, metaphase, anaphase and telophase.
The homologous chromosomes when are found in a condensed form and are present in the centre of the cell or at the equatorial plate is known as the metaphase.
In case of mitosis since the division takes place in one cycle, therefore, metaphase is the phase whereas in meiosis since the division takes place in two-cycle, therefore, metaphase I is correct as during the metaphase II the chromatids are present at the centre.
