Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen

Answer:
Impairment of photosynthesis
Explanation:
The major effect of oil spilage is that it impairs or hampers photosynthesis.
Photosynthesis is the process where green plants manufactures their own food in the presence of sunlight and water.
Water is denser than oil. Therefore, oil floats on the surface of water. Oil on water surface acts as a blanket to sheild plants away from receiving direct sunlight. Sunlight is very important during photosynthesis.
In the absence of sunlight, plants are unable to manufacture their food.
They are also unable to receive carbon dioxide from the environment.
Adenohypophysis is also called as the anterior lobe or anterior pituitary gland. Because of its position in the front lobe of the pituitary gland, it is named as this. It helps the pituitary gland in the major productions of growth hormone, gonadotropic hormone, thyroid-stimulating hormone, prolactin, etc.
It could either be A or D
