Answer:
Self-antigens are not recognized and attacked by the T cells.
Explanation:
In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.

Answer:
D) Water dissolves some molecules while causing the aggregation of others because of hydrophobic and hydrophilic interactions.
Explanation:
Sugars tend to dissolve, while lipids aggregate out because sugar has hydrophilic (water loving) interaction with water and on the other hand lipids have hydrophobic (fear of water) interaction with water. Water is a polar solvent and only polar solute dissolve in it due to phenomenon of like dissolve like, while lipids does not dissolve in it because lipid is non-polar in nature. In this case, sugar is hydrophilic while lipids is hydrophobic.
