Answer:
<u>50%</u>
Explanation:
<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.
The Doppler radar used in weather forecasting measures the direction and speed, or velocity, of objects such as drops of precipitation. This is called the Doppler Effect and is used to determine whether movement in the atmosphere is horizontally toward or away from the radar, which aides in weather forecasting.
RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.
Answer:
High mass stars have to generate a lot of energy in order to balance the force of gravity. Therefore they are very hot and luminous. That explains their position high on the Main Sequence. On the other hand, low mass stars have to generate little energy in order to balance the force due to gravity.
