The lymph vessel flows from the tissue to the lymph nodes, flow to the largest lymphatic vessel in the thorax called thoracic duct, then drain to the subclavian vein.
The lymphatic vessel is a thin tubular organ made of the endothelial cell. It has a valve like the vein to prevent backflow of lymph. Lymphatic vessel delivers the lymph through the body and has a role in the immune system.
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)
Answer: The father donates the Y chromosomes, and the mother donates the X Chromosomes
Explanation:
This model suggests that the cell membrane is a dynamic structure, because the proteins and phospholipids move laterally within the lipid bilayer ( so it is more of a fluid than solid)
(Mark me the brainliest if this has helped)
<span>2. This type of microscope is called a scanning electron microscope. 3. The difference between these two cells are that one has a nucleus and the other one doesn't. A eukaryotic cell has a nucleus and a prokaryotic does not.</span>
