Answer:
The correct order would be
Sensory receptors in the arteries detect low oxygen levels.
↓
Sensory neurons generate an impulse.
↓
The central nervous system relays an impulse to certain brain regions.
↓
The brain sends signals through motor neurons.
↓
Isabel's breathing rate increases.
The working of the nervous system can be summarized as:
The receptors receives the stimulus which then send signals to the brain with the help of sensory neurons.
For example, sensory receptors in the arteries detect the low oxygen levels after which sensory neurons send the signals to the brain.
The stimulus or information is processed in a specified region of the brain which then sends the signals to the effector organ via motor neurons.
The action or reaction is generated at the effector site such as an increase in the breathing rate of Isabel in this case.
This phase in the life cycle of a plant is the asexual, spore-bearing generation of the plant, featuring diploid cells. This means the cells of the plant in this generation or phase have two sets of chromosomes in their cells. The zygote or fertilized cell is what conduces to form the sporophyte.

The answer is A, Sound waves must have materials to bump together to transfer the waves.
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water)<em> flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.</em>
