Answer:
B. only chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors
Explanation:
Receptors are chemical structures, that receive and transduce signals that may be integrated into biological systems.
Receptors that can be found in the mouth include: chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors.
<u>Chemoreceptors</u>
These are receptors that detects chemical stimuli, either molecules or ions dissolved in liquids. An example would be our taste buds in the mouth, because they respond to specific molecules or ions in our ingested food.
<u>Thermoreceptors</u> responds to changes in temperature. These receptors are present in the oral cavity, skin and hypothalamus.
Mechanoreceptors are receptors that respond to distortion of the plasma membrane that occurs due to touch, pressure, vibration, stretch, stress or strain
. They can be found in the mucosae of ginviva (gum), cheek, tongue and soft and hard palate.
<u>Nociceptors</u> are receptor responds to painful stimuli. The purpose of nociceptors is to inform the body of injury, damage or threat of damage to body tissues so that a response may be made. They can be found in the tooth pulp and within dentine cavity.

Answer:
The quarantine can be regarded as an "invisible barrier" that prevents the virus from spreading.
Explanation:
The curve of infections increases when the virus's infection rate in the population greater than 1. The emigration is one of the most important density-dependent limiting factors responsible for increasing the curve of infections, while immigration and the death rate are factors that reduce its maximum value.
Answer:
The correct answer is option - C. The tomato yield at the end of the growing season
Explanation:
The dependent variable in research or an experiment is the factors that are being affected by the independent variables. The dependent variable is being tested or measures in an experiment and its measurement alter with the change in an independent variable.
In this research amount of the fertilizer is an independent variable that effect different dependent factors such as temperature, plant size, and sunlight but the tested variable that is tomato yield at the end of the growing season tested by weighing.
Thus, the correct answer is option - C The tomato yield at the end of the growing season.
Answer
The correct answer would be auricle and auditory canal.
The auricle or pinna is the externally visible part of the ear. it is mainly composed of cartilages and integuments. It is connected to the surrounding parts with the help of muscle and ligaments.
It helps in focusing the most of the sound vibrations towards inside the ear.
It opens into the auditory canal which serves as the pathway for sound waves to the inner ear (tympanic membrane).
