Answer:
Antigen-presenting cells show digested antigens to T cells through the MHC on their surface, which allows the T cell to “see” the antigen and recognize it as foreign. The connection between the MHC and the receptor on the T cell is the first signal necessary to activate the T cell to respond to a tumor and destroy it.
Explanation:
According to the graph, the correct answer is - Changes to vessel speeds and lanes have been effective in preventing population declines in the right whale population, and no further actions are needed.
Both methods seem to be pretty effective, and since the implementing of the changes of the lanes, the number of the right whales has been steadily growing, and after the vessel speeds limitations were added, the population of the right whales started to rise even quicker. Obviously, when both of the measures were in force, the effects were the best for the right whale populations.
True
The greater the object weighs (volume) the heavier it is, and it the object is heavier, the the buoyancy force will be higher

This is a matter of opinion, it can't be wrong. As long as you back up your answer. Add in personal experience. When you stir in lemonade mix to your glass of water, does stirring more make it stronger? Cite some evidence, and you should be fine. Hope this helped.
