As we know that the plants is universal producer.Plant absorb CO2 from atmosphere by the help of photosynthesis from where plant make glucose ,oxygen and energy and then plant exhale O2 but in plants there is another process is going on called respiration which exhale same amount of CO2 as consumed in photosyntesis and in autumn the leaves fall on the soil which on later decomposed and release carbon dioxide this whole cycle is called carbon cycle !!
Answer:
e. whether or not the impulse begins in the CNS
Explanation:
Nerve impulse is action potential movement through the axon. Nerve impulse propagation has its velocity (speed at which nerve impulse travels down the axon) which depends on many factors. For example, myelination increases the conduction velocity. Also, the larger the diameter of an axon, the higher the velocity is. Nodes of Ranvier present on the axons, and myelin sheath between the nodes act as a good electrical insulator which also increases the velocity.
The primary source of the greenhouse gases on the Earth is the burning of the fossil fuels. The fossil fuels are used for the generation of electricity in the thermal power plants. The fossil fuels are used to power the engines in the various vehicles like the aircraft, cars, bus, trains and trucks. The fossil fuels are also used for conventional heating of the home during the cold season. When the fossil fuels are burned they release smoke that has carbon dioxide, carbon monoxide, and soot in it. These chemicals trap the heat of the Earth leading to global warming.
