Answer:
<u>3. Hot spots , 4. S shaped mid oceanic ridge, pacific ocean</u>.
Explanation:
- The Hawaiian islands are located on the hotspots that are formed by the collision of two strong plates and the presence of volcanoes and high magnitude earthquakes as the pacific plate is continuously moving on the western side as its subducting under the North American plate and hence shrinking in size.
- The s-shaped Atlantic ocean has mid atlantic ridge and as this ocean spreads the lava is up welding across the ocean floor and hence the opening of the atlantic plate is seen.
Answer:
Autotrphic means that the organism can produce their own food through photosynthesis.
Two ways:
1. In prophase I of meiosis the homologous chromosomes synapse and crossing over occurs. This switches sections of two of the sister chromatids so the outer two chromatids have the same mix of alleles as the parents and the inner two chromatids have new combinations of alleles.
2. Meiosis puts only one of each kind of chromosome in the gametes, selecting one of each homologous pair at random. Then when each gamete joins with the gamete from the other parent, there are practically infinite combinations of the alleles possible.
