When a muscle cell contracts some myosin heads bind to actin molecules as other myosin heads release from actin molecules.
Muscle contraction occurs when the thick filament and the thin filaments slide over one another in a series of repetitive events.
Answer: The answer would be D
Explanation: Hope it helps :)
The given question is incomplete.The complete question is T/F When performing column chromatography to purify a protein of interest, one needs an assay to identify which fractions that contain the protein of interest. True or False: As discussed in lecture, we use a different assay for each different protein that we purify (For instance, the assay for protein A will be different than the assay for protein B which will be different than the assay for protein C, etc).
Answer: True
Explanation:
The sample contains different types of proteins in it and when the sample into chromatography column.
Different proteins have different affinity and based on the molecular size and weight they are separated.
So, according to the question if some one wants to assay protein A, it will be different for the protein B and different for the assay of protein C. This means that assays for different proteins will be different.
Hence, the given statement is True.
Answer: I believe the Lateral Lines are made of mechanoreceptors called neuromasts....
I know that hair cells, like the ones inside a human ear, are used as well.
Electric motors transform electrical energy into mechanical energy so the answer would be B.
