Answer:
Nitrogen fixation
Explanation:
Certain soil bacteria, e.g., <em>Azobacter spp</em> can combine free nitrogen of the atmosphere with oxygen to form nitrates. This is called <u>nitrogen fixation</u>. Other nitrogen-fixing bacteria such as Rhizobium form symbiotic unions with the roots of leguminous plants called root nodules. They fix nitrogen to form nitrates which are used up by the host plant. Nitrifying soil bacteria, e.g., <em>Nitrobacter </em>convert nitrites to nitrates in a process called <u>nitrification</u>.

Answer:
Some major functions of skeleton are below
Explanation:
Support and shape
bones support soft tissues and serve as attachment site for most muscles and provide shape to the body
Protection
Bones protect critical internal organs, such as brain, spinal cord, heart and lungs.
Movement
skeletal muscles attached with the bones help in moving the body
Mineral homeostasis
Bones serve as store for calcium phosphorus potassium sodium. Through negative feed back mechanisms bones can release and take up minerals to maintain homeostasis
Blood cell production
red and white blood cells are produced in bone marrow, a connective tissue found within bones
uracil
Explanation:
because the rest are part of the DNA strand
