<u>ANSWER:</u>
The correct answer is Predicts.
<u>EXPLANATION:</u>
Prolonged viewing of violent TV programs leads to those viewing the violent programs to react in a violent manner to situations in routine life. When one watches a violent TV program in which a good character reacts violently to a situation, it is accepted by the viewers as the right way of dealing with situations. Therefore, it can be predicted that most viewers will react to the situation violently like the good character of the program.
They are primary subtractive colours, because each of them can be formed by subtracting a primary additive colour from the white light (blue, green, and red).
If a planet exists near a distant star, the star may have a very slight back and forth motion.

Answer:
- The lac operon can be activated by the binding of allolactose to the repressor protein, releasing it from DNA and thereby allowing for transcription to occur.
- In response to low glucose levels, cAMP is upregulated; the binding of cAMP to the cAMP receptor protein triggers the activation of the operon.
Explanation:
Lactose operon or lac operon (includes lacZ, lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent (or at low level). The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.
When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.
CAP detects glucose (via cAMP) and activates transcription when glucose levels are low.
