Answer:
Reflex action is the sudden uncontrolled reaction towards a certain stimuli eg response to hot iron
Reflex arc is the path taken by reflex action to a certain stimuli
Diagram depends to
Receptor(eg skin), receptor nerve(sensory neurone),centre reflex arc(spinal cord most of reflex action) they met relay neurone, motor neurone and ends at reflexor (eg muscle)

They may have som bad side effects such as nausea, indigestion, vomiting etc. Also the bacteria change or adapt if not taken correctly so they are no longer affected by the antibiotic.
- Thermosphere - Fourth layer of Earth's atmosphere.
- Aurora Borealis - Ionosphere layer of thermosphere.
- Large-scale air turbulence and mixing at this layer - Troposphere
- Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
- The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
- Maximum ozone - Ozone layer in Stratosphere
Explanation:
Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.
1. Troposphere -
- The first layer of the atmosphere.
- Weather occurs in this layer.
2.Stratosphere -
- The second layer of Earth's atmosphere.
- Contains Ozone layer.
3. Mesosphere -
- The third layer above the stratosphere.
- Coldest layer.
4. Thermosphere -
- The fourth layer of the atmosphere.
- Warmest layer.
- Ionosphere - lowest level of thermosphere above mesosphere.
- Aurora Borealis, Northern and Southern lights are seen in this layer.
- Exosphere - outermost layer of thermosphere.
- Satellites are in this layer.
- Outer space with no gravity.
