Answer:
Explanation:
Since Mark's wife was a carrier, it means that she is heterozygous for the trait. And after Mark got tested, they decided to have children due to no increased risk if they do have children, it means the condition is not an autosomal dominant condition but a recessive condition because if the condition is dominant, only one copy of the affected allele is needed to increase risk.
Thus, with a no increased risk, it means Mark is normal i.e. carries no copy of the recessive allele.
Answer:
plasma membrane of the target cell
Explanation:
There are two main types of acetylcholine (ACh)receptors:
- muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
- nicotinic ACh receptors (nicotin is agonist) which are ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).
Answer:
The correct answer will be- the head globular domain of the motor protein.
Explanation:
Motor proteins are a class of proteins which can move along the cytoskeletal system of the cell using a mechano-chemical mechanism which involves conformational change, filament binding and releasing.
The kinesin and myosin are two important motor proteins which move along the actin filaments by converting the chemical energy of the ATP into motion.
The structure of motor molecules contains two globular head domains which bind ATP and ATPase enzyme break down the ATP releasing energy utilized by the motor protein to move.
Thus, the head domain of the motor protein enables movement.
It would possess the same value. Remember the atomic number of an element corresponds to the number of protons found in an atom of that element.
Answer:
A measure of how innaccurate a measurement is, standardized to how large the measurement is. Found by the formula (measured value-actual value)/actual value*100%J
Explanation:
Simply a percentage, the definition of it is up above.
