Concept explainers
The process in which incoming sensory stimulation is converted to electrical signals in neurons is called
- a. an action potential.
- b. sensory reception.
- c. perception.
- d. sensory transduction.
- e. perceptual transduction.

Introduction: The senses allow an individual to know about its environment. A sense consists of systems that have specialized cells. These cells help to detect a specific type of physical and chemical stimulus, and send signals to the central nervous system.
Answer to Problem 1TY
Correct answer: Sensory transduction is the process in which incoming sensory signals are converted to electrical signals in the neuron. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
The sensory system of an animal is responsible for the conversion of a physical or chemical stimulus from their body or external environment into signals. This causes a change in the neuron’s membrane potential. This process is known as sensory transduction. This process involves changes in a cell, such as opening and closing of ion channels which causes an action potential in the neurons.
Option d. is given as, “sensory transduction”.
The process in which incoming sensory stimuli are converted into electrical signals is known as sensory transduction. Hence option d. is correct.
Reasons for incorrect answer:
Option a. is given as, “an action potential”.
An action potential is the difference in the potential needed for impulse transmission. Hence, option a. is incorrect.
Option b. is given as, “sensory reception”.
When a sensory receptor is activated in response to any signal, it is known as sensory reception. Hence, option b. is incorrect.
Option c. is given as, “perception”.
The awareness of the stimulus is known as perception. Hence, option c. is incorrect.
Option e. is given as, “perceptual transduction”.
The conversion of a perceptual signal is known as perceptual transduction. Hence, option e. is incorrect.
Hence, the options a., b., c., and e. are incorrect.
The process in which the incoming sensory stimuli are converted into electrical signals is termed as sensory transduction.

- You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forwardDesign a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forward
- A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobinarrow_forward

It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
