Between 1932 and 1968, a chemical factory in Japan released mercury-laden wastewater into Minamata Bay. The mercury was modified

to methylmercury by bacteria living in bottom sediments. This resulted in severe mercury poisoning in over 2,000 people. Since people don't eat bottom sediments, what is the best explanation for how toxic levels of mercury ended up in affected people?

The toxic still ended up to the affected people because of bioaccumulation. This means that organisms who might have consumed the said mercury was consumed by some larger organisms. These larger organisms were eaten or consumed by human beings. The toxin, in other words, was just passed on to different species.

Sauron [17]
A scientific argument will be considered invalid if the evidence supporting the argument is based on independent data.
If you are only referring to a single scientist or a single study conducted on a certain topic, it means that it hasn't been researched enough for the argument to be reliable. Every scientist needs to refer to other studies and other scientists and their work if they want their arguments to be valid.

In the following image, what conclusion can you draw about the speed of the planet at location A compared to location B? (2 poin
aleksandr82 [10.1K]

The answer is; When the planet is at A it is moving faster than at B.

This is because when the planet is closer to the sun at point A, it is experiencing a stronger gravitation, by the sun, pull than at point B. Therefore, its acceleration due to gravity at point A is higher than at point B.

Only in plant cells.

Kruka [31]

Answer:

The correct answers are:

A) Antigen-presenting Cell - both responses.

B) Plasma Cell - humoral immune response.

C) Memory Cells - both responses.

D) Antibodies - humoral response.

E) B Cells - humoral immune response.

F) Helper T Cells - both responses.

G) Cytotoxic T Cells - cell-mediated immune response.

Explanation:

Acquired immunity involves both a humoral immune response and cell-mediated immune response, since these two responses are not independent of each other, but instead "work together" in order to perform a better response.

Humoral immunity is mediated by macromolecules (like antibodies) found in extracellular fluids, and <u>is activated much more quickly than the cell-mediated one</u>, but it doesn't last as long. The Cellular immunity, on the other hands, <u>needs the prior activation of cells such as macrophages and lymphocytes</u>.
