Answer:
The correct option is <em>B. Crossing- over </em>
Explanation:
In biology, crossing over can be described as a phenomenon by which homologous chromosomes exchange segments during the process of meiosis.
The unexpected results came because the DNA segment between the homologous chromosomes was exchanged during meiosis. The alleles got shuffled by this process and hence showed the unexpected results.
Crossing over and independent assortment are phenomenon which occurs only during the process of meiosis. These phenomenons cannot be observed during mitosis.
Advanced technologies like remote sensing have modified the way by which maps are constructed. Remote sensing is the procedure of collecting information about Earth with the help of instruments mounted on airplanes, satellites, or ships.
Remote sensing helps in monitoring and detecting the physical features of a region by determining its emitted and reflected radiation at a distance from the targeted region. Unique or specialized camera gather remotely sensed pictures of the Earth that assists the researchers in sensing the things about the Earth.
Answer:
1 all of the above.
2 fire and land slide.
3 forest fire or all of the above.
None, egg cells don't have chromosomes. No, sex cells do have chromosomes. meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.
