Answer:
C
Explanation:
When two species share a common niche, then one is bound to exclude the other. This is due to the stiff competition for resources. The species with a slight advantage in acquiring the resources will edge out the other species from the environment. This has been demonstrated by George Gauss using two Paramecium species grown in the same media in the lab. <em> P. aurelia</em> outcompetes <em>P. caudatum</em>
50 percent, Tt crossed with a tt will be Tt, Tt, tt, tt, so it will be 50 percent
Answer:
See the answer below
Explanation:
The question that can be answered with the F2 cross would be <u>if the yellow flower color is dominant over the red flower color in the species</u>. In other words, <u>whether the inheritance of flower color follows a simple Mendelian inheritance or otherwise can be answered.</u>
<em>Assuming that the inheritance of the flower color follows the Mendelian pattern, the red flower trait would re-emerge among the F2 offspring and the ratio of yellow to red flower offspring would approximately be equal to</em><em> 3:1.</em><em> Otherwise, a more complex pattern of inheritance would be involved.</em>

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
humans and normal rodents.
