Answer:
Option C, Parasympathetic nervous system stimulation resulting in airway constriction
Explanation:
Complete Question
When a client with a history of asthma takes a walk outside on a windy day with high pollen counts, she may experience an asthma attack, resulting in an increase in respiration rate and wheezing. The body's response is likely related to which pathophysiological principle?
Select one:
a. Influx of macrophages to wall of the pollen, thereby stopping the attack
b. Release of catecholamines causing blood vessel constriction
c. Parasympathetic nervous system stimulation resulting in airway constriction
d. Inhibition of glandular secretions, which causes build up of mucus in the lungs
Solution
The parasympathetic nervous system consists of cranial and sacral spinal nerves. It is responsible for doing the work of sympathetic system thereby decreasing the rate of respiration and heart. During windy climate when pollen grains are in excess, the rate of respiration needs to be higher in order to get sufficient supply of oxygen. But due to activation of parasympathetic nervous system the body tries to preserve its energy by decreasing the rate of various bodily functions and
Hence, option C is correct
Dendrites are part of a neuron acts like an antenna to receive messages from other neurons and transmits these messages toward the cell body. These structures are commonly seen as large extended parts or branches of the neuron. It has corresponding partner called an axon which transmits signal away from the cell body (to another neuron).
Polyploidy is a major force in the evolution of both wild and cultivated plants- In addition, polyploidy often results in reduced fertility due to meiotic errors, allowing the production of seedless varieties...
The resting metabolic rate is the amount of energy (calories) required by the body to function at the resting state. This measurement has into account basic metabolic activities, including energy (calories) used to eat.
The resting metabolic rate includes different metabolic activities:
- breathing
- circulation of blood
- organ functioning (e.g., digesting food)
- basic neurological functions
- The resting metabolic rate of the metabolism is measured in strict and steady (resting) conditions.
- On the other hand, the basal metabolic rate measures the minimum amount of energy (i.e., calories) required to perform the most basic life-sustaining functions.

Answer:
In the middle of the pile of grass.
Explanation:
The fire would be most likely to start in the middle of the piles of grass if spontaneous combustion occurs because the heat doesn't easily move through the medium due to the insulating nature of grass. A pile of grass can catch fire due to spontaneous and quick combustion in the middle of piles of grass. So the fire starts in the middle of the pile of grass.
