Answer:
Explanation:
Coffin-Lowry syndrome is caused by changes (mutations) in the RPS6KA3 gene and is inherited in an X-linked dominant pattern. Males are usually more severely affected than females.
Diffusion- spreading particles (ex: angel of perfume spreading throughout the room)
Active transport- movement of ions from a low concentration to a higher concentration.
Osmosis- movement of partials through a semi-permeable membrane from a less concentrated solution to a higher one.
The question provided is not complete as it lacks the group of choices, however the group of choices are given as follows:
A. A contraction fails to occur because an action potential is not generated in the muscle cell.
B. A contraction fails to occur because this toxin directly prevents ion release from intracellular stores.
C. A contraction fails to occur because neurotransmitter release by the motor neuron is blocked at the neuromuscular junction.
D. A contraction fails to occur because this toxin prevents cross bridge formation and thereby directly prevents contraction.
E. C and D are both true
Answer:
The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.
Explanation:
A muscle contraction takes place when action potential bring to muscles by nerves, which is traveled with the help of motor neuron and imitated the muscle contraction.
Acetylcholine or Ach is a chemical messenger to bring the nerve impulses between a nerve and a muscle. If the receptor is block with applying toxin muscle will not contract as ACh will not be able to propagate the nerve impulse to the muscle so there will be no action potential.
The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.
Nucleic acids because the DNA of a organic compound is part of the nuculis family
<h2>Chemical senses </h2>
Explanation:
Olfaction and gustation are called chemical senses because they have sensory receptors that respond to molecules in the food we eat or in the air we breathe
- Olfaction is odor detection, the olfactory receptors are located in the olfactory epithelium, a dime-sized area at the top of each nasal cavity
-
An epithelium is a layer of cells, so the olfactory epithelium is a layer of cells devoted to the sense of smell
- The receptors feed directly into a part of the brain called the olfactory bulb
- Gustation is usually called the sense of taste, despite the fact that olfaction dominates our ability to taste foods and liquids
- Taste cells are gathered together in taste buds on the tongue, and taste buds are hidden in bumps on the tongue called papillae
- Olfaction and gustation are are stimulated by chemicals, the molecules of which interact with receptors to produce a generator potential (olfaction) or receptor potential (gustation)
