Vinvika [58]

Answer:

A. I, IV, II, III, I

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).

The correct sequential order for the transmission of a signal through the nervous system;

1. Nerve impulse is triggered.

2. Synaptic vesicles release neurotransmitters.

3. Neurotransmitters diffuse across synaptic cleft.

4. Receptors bind neurotransmitters.

5. The whole process is started all over again when the nerve impulse is triggered.

Is the temperature profile in the thermosphere more like that of the troposphere or the stratosphere?
podryga [215]

The correct answer is: stratosphere.

This is because their temperatures are rising instead of decreasing.

There are 4 primary layers of the atmosphere on Earth:  

Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.

Stratosphere  (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.

Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer

Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.
