Answer:
The correct answer is bone marrow and thymus
Explanation:
Primary lymphoid organs are bone marrow and thymus. Both organs consist of primary lymphoid tissue where B and T cells are produced.
Lymphocytes are also complete the early phases of maturation in the primary lymphatic organs in the body. In humans, B cells are generated and mature in the bone marrow. However, T cells are produced in the bone marrow and maturation takes place in the thymus.
Thus, the correct answer is the bone marrow and thymus gland.

Competitive exclusion state that or show that two organisms who compete for the same resource in the same habitat cannot occupy the same niche and cannot coexist because the stronger organism or superior one tend to outcompete the weaker organism thereby leading to the exclusion of the the weaker organisms. It is a principle in ecology also called Gause's law.
While plants can produce their own energy using the process of photosynthesis, animals (and other organisms that can’t do photosynthesis) must eat to get energy from food molecules. Just like energy can be stored in the chemical bond between the second and third phosphate of an ATP molecule, energy can also be stored in the chemical bonds that make up food molecules. Most of the energy that we use comes from molecules of glucose, a simple sugar.
