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.
Answer: Fertilization
Explanation: Fertilization occurs when a sperm and an egg combine
Answer:
Zone 4
Explanation:
The phreatic zone, or zone of saturation, is the part of an aquifer, below the water table, in which relatively all pores and fractures are saturated with water. Above the water table is the vadose zone.
The area between the top of the water table and beginning of bedrock/impermeable rock is the saturated zone.
The inner ear is the location where fine changes in sound pressure in the environment are translated into neural signals. The inner ear is the most inner most part of the vertebrate ear. It is mainly responsible for sound detection and balance. It consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system comprising of two main functional parts (cochlea and the vestibular system).
Divergent Boundary:
A divergent boundary is a linear feature that includes two tectonic plates moving <em>away </em>from each other. When plates separate, it allows molten lava to seep through and spill over, creating new crust where the previous tectonic plates existed. Divergent boundaries are mostly found in the ocean floors.
Hope this helps!!
