The sensory input initiated from the spinal cord before reaching to the brain . The information firstly goes to first order neuron where it receives impulses from skin and then transferred to the spinal cord.

Some sensory pathways consists of chain of neuron that transfer from receptor organ then to cerebral cortex that is responsible the perception of sensations. Sensory input is converted into electrical signals are known as nerve impulse.

This nerve impulse are transmitted into into brain. The correct order is Receptors - Sensory neuron- Spinal cord - Motor neuron- Muscle.

Impulse are the strong desire to act or that causes something to happen or happen more quickly.

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosys
-BARSIC- [3]

Answer:

The flow of energy in ecosystems is unidirectional or one-way.

Explanation:

Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.

Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to  organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.

Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.

Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

A sample of gold (AU) has a mass of 57.01 g.
Kamila [148]

A). Calculation: Given mass of Au * 1mol of Au/molar mass of Au= # of moles ;

57.01 g Au*1 mole of Au/196.97g Au=0.3 moles of Au.  So the answer is 0.3 moles of gold(Au). Good luck on the rest,  and message me on Brainly if you need more help. I'll be happy to.
