Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.
It is not common but yes an ab parent can have an O child
An environmental scientist might study the effect of soil pollution on plant growth. This is true.
Hope this helped :)
The answer is Photosynthesis
<span>Wide variety of fish species. It always includes this intertidal zone and is
sometimes used to mean the same as the intertidal zone. Though, the meaning of
"littoral zone" can be overall well beyond the intertidal zone. The
littoral zone is the same as a sea, lake or river that is close to the shore.
In coastal environments the littoral zone extends from the high water mark,
which is very rare inundated, to shoreline areas that are permanently submerged.</span>
