Clearcutting results in the removal of topsoil and some animal habits, which can prevent the forest from being able to grow again. While it is cheap, the damage to the food chain and surrounding ecosystem can destroy entire regions.
<span>Hiking in the morning, assuming you have not eaten anything prior to the hike, results in your body having to perform work with lowered glucose levels, thus causing the body to feel out of breath.</span>
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.
<span>The genes BRCA1 and BRCA2 are the genes that suppress the growth of
tumors in the body. If there is a mutation in any of these two genes, there
will be a lower chance of inhibiting tumor growth. This will lead to a higher
chance of cancer and tumor development in the body.</span>
