But an egg or sperm only has one. That one is chosen at random, through a process called meiosis. When meiosis messes up, you can end up with to many or too few chromosomes. One extra chromosome in a egg or sperm means three in the fertilized egg and so trisomy.
The options for this question are:
A. Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B. All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
C. Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
The best answer choices are:
A & C
Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
Explanation:
Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Sensory receptors located in the dermis or epidermises of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors.

<h3>What is a cookbook?</h3>
A cookbook is a book that contains various recipes and how they can be prepared. It is commonly used by chefs and other people who are into the cookery business.
Now we are told that the student likes the meat at medium which is a temperature of 160° Fahrenheit. We have to to convert this given temperature to degree Celsius.
Now using the relation;
C = (F - 32) * 5/9
C = (160 - 32) * 5/9
C = 71 degrees Celsius.
