Answer:
A) The pollen grains will be pure red.
Explanation:
Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).
In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte). When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.
Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.
There are multiple energy source in the ocean. The one thats probably the most common one are Dams. Although Dams can cause some serious flooding. Another one is Tidal energy. Tidal energy is something that turns the energy of tides into energy through Kinetic motion.<span />
<h3><u>Answer;</u></h3>
absorbed by Earth’s core
When energy from the sun reaches Earth, it is not <em><u>absorbed by Earth's core.</u></em>
<h3><u>Explanation;</u></h3>
- <em><u>The energy from the sun reaches the earth, such that 23 percent of the incoming solar radiation is absorbed by the atmosphere by water vapor, dust and ozone. </u></em>
- <em><u>48 percent of the solar energy is absorbed by the earth's surface, this translates to 71 percent of the energy which is absorbed by the systems of the Earth.</u></em>
- <em><u>The remaining 29 percent is reflected back to space by clouds, atmospheric particles etc. </u></em>
