Answer:
The correct answer is option C. "Uncovered meat that had contact with air".
Explanation:
In 1668, the Italian scientist Francesco Redi performed a celebrated experiment to prove that maggots are not spontaneously created by placing fresh meat in each of two different jars: one opened and one covered with a cloth. Redi used an uncovered meat that had contact with air as a control, expecting that flies will come in and the maggots will be developed as they do in nature.
ATP molecule functions as the power source for a cell. Sometimes it is compared to a battery, which is a pretty fair analogy, but it is more mobile and flexible in its functions than a battery is.
Because its is a bit more rare than iron .
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
