the two statements are 1 and 4
Answer:
Sustainable use of the environment
Explanation:
Be it the ecosystem or the food you eat, if you just take up whatever you need instead of over exploiting the resources, another life can benefit from it. The relationship we need to form with our environment should be mutualism or commensalism but not parasitism.
It would have to be the last statement
Answer:
The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.
Explanation:
Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.
The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.
Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.
Answer:
The correct option is b) motor output of the spinal cord
Explanation:
Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.
The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.
