Answer:
a. antigen
Explanation:
The Immune system is composed of immune cells that defend the body against foreign substances such as bacteria or virus. Lymphocytes (B and T cells) are one of the main immune cells
Lymphocytes have the ability to recognize and bind to antigens, wich are substances foreign to the body ( i.e bacterial or virus elements) that evokes an immune response.

Answer:
D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere
Explanation:
Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.
CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.
The noble gases already have a full outer shell. The noble gases break the trend by being less reactive than the elements to their left.
