<span>Genetic defects are associated with both abnormal autosomes as well as abnormalities in the gender-based chromosomes. Autosomal abnormalities occur if there is an abnormality on any of the first 22 pairs of chromosomes. The abnormality is linked to gender if it occurs on the twenty-third chromosomal pair. Both of these abnormalities are due to chromosomal errors or genetic mutation.

There are two types of cellular respiration, these are aerobic and anaerobic respiration. Anaerobic respiration can occur in the absence of oxygen, but for aerobic respiration to occur, oxygen must be present. The process of aerobic cellular respiration involves a series of oxidation and reduction reactions and the oxygen molecule serve as an electron donor and acceptor during this process. Thus the stages of cellular respiration can only occur if oxygen is present. <span />
Answer:
An extracellular molecule activates a membrane protein, which in turn activates molecules inside the cell.
Explanation:
Signal transduction may be defined as the cellular process in which the signal is transmitted into the cells. The signal transduction results in the detection of the stimuli and the effects generated in the body.
The signal transduction initiates the series of cascade for the signal transmission. The protein is activated by the extracellular molecule and activates the different molecules by the phosphorylation at the different steps of the transduction.
Thus, the correct answer is option (c).
