Answer:
None of the birds have the same niche.
Explanation:
They all have different niches because of the food they ate. Over time, they were gentically changing to adapt to their own food.
- drought-tolerant
- able to withstand the harsh desert environment
- remain green
+ its presence shows that there is water underground
The answer is 4 new (daughter) cells.
In meiosis, it produces 4 daughter cells which are genetically different from both the parent and the other daughter cells.
the parent cell first duplicates its chromosomes, just like mitosis (the kind of division that leads to 2 genetically identical daughter cells) . Then it divides, leading to 2 genetically identical daughter cells. But this does not end here. The 2 daughter cells further divides into total of 4 daughter cells, but without duplicating the DNA. That's why, the daughter cells has different DNA materials.
These daughter cells has half of the parents chromosomes, and we call them haploid.
Haploid cells are usually common in gametes. When an organism reproduces sexually, 2 gametes fuse together and leads to diversity.
Sickle cell anemia is persistent in the tropics because those with sickle cell anemia cant contract the malaria virus because of the shape of their blood cells, and this is advantageous in the tropics where there are more malaria cases. So those with sickle cell anemia live to pass on their genes.
