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.
Low tar cigarettes have been shown to be no safer than regular cigarettes, and smoking them does not lower the risk of cancer or other diseases.
I would say it's not a good idea
Initiating blood clot is the main function of platelets.
Answer:
Explanation:
Here, cell C-2 needs to express GFP and therefore, GAL4 should be functional in cell C-2. This can be achieved by expressing GAL4 in Regulatory DNA construct 3, and expressing GAL80, an inhibitor of GAL4 in Regulatory constructs 1 and 2. This arrangement expresses GAL4 in columns A and C, and inhibits GAL4 due to GAL80 expression in Columns A and B; and in rows 1 and 3.
Therefore, the only cell that expresses GAL4 is cell C-2.
The arrangement is:
1. Construct 1 should express GAL80
2. Construct 2 should express GAL80
3. Construct 3 should express GAL4
4. Construct 4 should not be used
Answer:
The pulmonary vein and the jugular vein.
Explanation:
The greatest difference between the pulmonary vein and the jugular vein is that pulmonary vein takes oxygenated blood from both lungs towards the left atrium of heart while jugular vein takes the deoxygenated blood from head back towards right atrium of heart through superior vena cava.
So, the main difference is oxygenated and deoxygenated blood in the above mentioned veins.
