Maybe because the skin lacks oils which moisturize the skin. When you put lotion on your skin you moisturize it causing ti to be supple.
Answer:
Because T-cell-independent antigens do not activate helper T cells, they fail to induce B cell memory, affinity maturation, or class switching, all of which require help from T cells. They therefore mainly stimulate the production of low-affinity (but high-avidity) IgM antibodies.
Explanation:
Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation processes
occur to help species survive and thrive in the ecological balance of life.
Structural adaptations are physical features of an organism that adapted through
time. An example of this are the bills of a bird and the fur of bears that they
generally need for their survival; birds for hunting, and bears to protect them
from low climate areas.

Behavioral adaptations refer to particular things that an organism or organisms
do to survive. In the example above, behavioral adaptations that birds do is
through certain bird calls and migration, while bears hunt during warmer
seasons and hibernate during winter season. </span>
