This answer is B because it is not made up of cells, the easiest way to know this is because viruses are much smaller than a single cell, meaning its impossible for it to have cells or be a living organism.
The specialized hearing receptors found in the cochlea would be hair cells.
The sequence containing short stretch of hydrophobic amino acids fused to the c-terminus of GFP, will be probably found outside the cell because it has no signal sequence.
GFP, called the Green Fluorescent Protein emits a green fluorescence when exposed to light. The protein was first isolated from a jellyfish <em>Aequorea victoria</em>. In laboratories, the protein is majorly used as a marker to track the movement of functioning of any substance.
Signal sequence are the short stretch oh polypeptides found attached to any protein to determine its target site. These sequences determine the pathway and the function that the protein will follow.

Answer:
A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable.
Explanation: Or
Oscillations in the activities of various cyclin-Cdk complexes leads to the initiation of various cell-cycle events. Thus, activation of S-phase cyclin-Cdk complexes initiates S phase, while activation of M-phase cyclin-Cdk complexes triggers mitosis.
