Answer:
2
Explanation:
endosperm, embryo, seed coat
1) pathogen enters body and releases chemoattractants
2) a phagocyte/macrophage is attracted by these chemicals
3) the phagocyte engulfs the pathogen using its pseudopodia
4) the membranes of both organisms fuse forming a phagosome
5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome
6) these enzymes digest the pahogen (hydrolyse the bonds)
7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)
Tectonic plate movements, volcanic eruptions, earthquakes, and climate change have shifted wildlife habitats, wiped out large numbers of species, and created opportunities for the evolution of new species. Hope this helped!
