Answer: C. is less likely to be eaten by a predator.
Explanation:
The adult seven-spotted cockroach is the prey of various other insects including beetles so mimicking the pattern of a beetle would send a message that it is a beetle and because the chemical irritant that the beetle has makes it get avoided by others, the cockroach gets avoided by other insects too who don't want to be sprayed. 
Of course this does not always work but it works for the most part and ensures the cockroach's survival. 
 
        
             
        
        
        
Answer:
The right answers are mentioned in the picture.
A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.
It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

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).
