Answer:
I think C. Petri dishes
Explanation:
"The most common growth media nutrient broths (liquid nutrient medium) or LB medium (Lysogeny Broth) are liquid. These are often mixed with agar and poured into Petri dishes to solidify. These agar plates provide a solid medium on which microbes may be cultured."-https://courses.lumenlearning.com/boundless-microbiology/chapter/culturing-bacteria/
I hope this helps!
 
        
                    
             
        
        
        
Explanation:
The animals that remain active during the day are called the diurnal while animals that remain active during night are called the nocturnal. 
As per the question we can distinguish organisms and plants and see their behavior during the day as well as during night. Diurnal are organisms that activate during the day, while the organisms that activate during the night are called the nocturnal.  Among the animals, nocturnal animals are bats, mouse, hedgehog, etc. The appearance of the nocturnal animals is due to the following three factors :
-- to avoid heat
-- to hunt 
-- to mate
 
        
             
        
        
        
Answer:
<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>
Explanation:
Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.
Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription.  RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand  and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
