Disease-causing agents are called pathogens. It is the broadest term that can be used which refers to any bacterium, viruses or any microorganism that causes disease. It is also known as infectious agent. It can also be defined as an agent that disrupts the normal function of a multicellular animal or plant.
The Cell wall is found in plant cells and not animal cells
This is kind of hard to show without the picture, but to make an ionic bond with Na and Fl you would have the sodium move an electron to the fluorine, so the answer is C! This is because of the fact that sodium has an outer shell valance electron (so it's unstable) and the fluorine would accept that because it is missing an electron in the outer shell. So this sharing would lead to the bond being created!
The mother has the alleles A and M, given that her blood type is A MM. Since the child has blood type AB MN, then the child has the alleles A, B, M, N. However, the alleles B and N, cannot have come from his/her mother and must have come from the father. Therefore, we are looking for a father with the alleles B and N. Based on this conclusion, the child's father is either Tom (with blood type AB MN) or Bill (with blood type B MN).
