When Sarah performed this experiment, she changed the levels of nitrogen in order to observe the changes in the morphological features of the plant.
All of the characteristics of the plant that she observed were dependent on multiple different things, but the level of nitrogen was an independent variable that she was changing at her will.
Answer:
According to the genetic code, the amino acids are the following:
- Glycine: encoded by GGC, GGA and GGG codons
-Arginine: encoded by AGA and AGG codons
-Lysine: encoded by AAA and AAG codons
-Glutamic acid: encoded by GAA and GAG codons
Explanation:
The probabilities to observe an amino-acid formed by Glutamic acid in the coding sequence is 2/9 for each codon
Answer:
These creatures depend on the sea water for nutrients, protection and to move about. At low tide,many of these creatures are exposed to the air, leaving them at risk of predator attacks andoxygen depletion. The whole eco-system of the tide pools would simply not exist without theconstant movement of the tides
