The
Thymocyte progenitors enter the subcapsular region of the thymus as
double-negative cd3- t cells where the double negative refers to lack of
cluster determinants CD4 and CD8. Double-negative cd3- t cells exist as small population
that is 1%-5% of lymphocytes in the lymphoid organs and peripheral blood of

Answer:
<em>d. enhances the ability of spores to penetrate the layer of stagnant or unmoving air above the fruiting body.
</em>
Explanation:
Two things rely on the movement of the spores in the air to the great heights. Velocity is one, and mass would be another. Because if the spores are to grow in the air they need both mass and speed.
Spores produced by single ascus can not accomplish this by themselves. Thereby spores are emitted by asci groups.
Spores obtain the ability to penetrate the layer of stagnant or up-moving air above the fruiting body by being released by community of asci.
Sickle-cell disease is common in tropical and sub-tropical regions because being a carrier, carrying a single sickle-cell mutation (sickle cell trait), affords some resistance to malaria.
