Answer:
In 2020 renewable energy sources produced more electricity than all fossil fuels (coal, gas, oil) together and now provide 45.3 percent of German electricity demand.In July 2019, figures published by the Fraunhofer Institute for Solar Energy Systems (ISE) report that renewable energy is for the first time providing more electricity than coal and nuclear power combined in Germany. Solar, wind, biomass and hydroelectric power generates nearly half of the country's output.
Plant decomposers would operate above the producer level. Two examples are earthworms and fungi. These would decompose dead plant matter into nutrients that are then re-assimilated by plants. Animal decomposers operate within the consumer levels, and would include species such as maggots, shrimp, clams, crabs, lobsters and flat<span>worms</span>. Nutrients recycled by these decomposers would also be recycled back to the producers.
Answer:
The efferent pathways of the ANS consist of 2 neurons that transmit impulses from the CNS to the effector tissue. The preganglionic neuron originates in the CNS with its cell body in the lateral horn of the gray matter of the spinal cord or in the brainstem.

Arrange the events of synaptic transmission in correct sequence
(1) sodium ions diffuse into the cell and cause a local potential
(2) neurotransmitter binds with receptor on postsynaptic cell
(3) neurotransmitter diffuses across the synaptic cleft
(4) membrane permeability to sodium ions on postsynaptic cell increases
(5) action potential causes release of neurotransmitter
Answer:
5,3,2,4,1
Explanation:
The firing of an action potential at pre-synaptic neuron makes its axon terminal to release the neurotransmitters in the synaptic cleft. The released neurotransmitter molecules then bind to their receptors present at the surface of the dendrites of the postsynaptic neuron. This binding opens ion channels and allows the specific ions to enter into the postsynaptic neuron. The opening of Na+ channels allows these ions to enter into the neuron and changes the membrane potential. This changed membrane potential is called local potential and is a depolarizing graded potential.
