The Aleutian Trench is formed by the subduction of the Pacific Plate underneath the North American Plate along the coastline of Alaska. What would most likely be observed at this tectonic boundary? (3 points) Select one:
a. Chasms reaching the mantle are caused by two tectonic plates moving away from each other
b. Creation of new seafloor formed from the solidification of magma between the plates
c. Explosions underneath the Earth's crust caused by the collision between two tectonic plates
d. Frequent earthquake activity caused by the movement of tectonic plates against each other

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
