Answer: In addition to having a 50% chance of inheriting autosomal dominant disorders from an affected parent, such a disorder is characterized by equal frequency of occurrence in both sexes (male and female).
Explanation: Autosomal dominant disorder has the following characteristics;
1. Appears in both sexes with equal frequency.
2. Does not skip generations.
3. Affected offsprings must have an affected parent unless they possess a new mutation.
4. Unaffected parents do not transmit the disorder.
5. When one parent is affected (heterozygous) and the other parent is unaffected, approximately 50% of the offsprings will be affected.
Answer:
Energy, carbon dioxide and water vapor
Explanation:
The final product of aerobic respiration are energy, carbon dioxide and water vapor.
- During aerobic respiration energy rich compounds are broken down into simpler units to liberate energy.
- This metabolic reaction is said to be a catabolic step or procedure.
- It is the reverse of what happens during photosynthesis.
- Therefore as glucose combines with oxygen gas, the product derived is energy, carbon dioxide and water vapor.
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.
