Answer:
A fixed set of steps and procedures
The correct answer is: 2)The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions
The light-dependent reactions is one of the two successive phases that occur during photosynthesis (other is light-independent reactions). The light-dependent reactions use sunlight energy to make the energy storage molecule ATP and the reduced electron carrier NADPH. In the light-independent reactions (also called Calvin cycle), CO2 is absorbed and fixed in order to build three-carbon sugars (glyceraldehyde-3-phosphate) and this process is fueled by, ATP and NADPH from the light reactions.
Answer:
Explanation:
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2.
<span>It is a common misconception that elephants existed the same time as the dinosaurs did when in fact they have evolved 3 or 5 million years after these creatures.
The tusks of the elephant would probably be the structure not present in early elephants. It is only through evolution that these tusks grew. Some scientists have hypothesized that these tusks develop from the elephants' incisors.

Explanation:
Codons describe the triplet sequence of bases present in an mRNA that code for proteins. They do this by specifying specific amino acids.
To answer this question, we need to know the genetic code. This can be found in various formats (usually tables) online or in textbooks. An example is attached.
Threonine is an amino acid with the three letter code Thr, and the one letter code T.
As you can see in the table, 4 codons (ACU, ACC, ACA, ACG) code for threonine
