Carlota’s body is made up of many cells. One thing that all her body cells have in common is that they contain genetic material in the form of DNA.
DNA (deoxyribonucleic acid) is the fundamental genetic material that carries genetic instructions for the development, function, and reproduction of all living organisms. It is found in the nucleus of cells and consists of four nitrogenous bases (adenine, guanine, cytosine, and thymine), a sugar molecule, and a phosphate molecule.
However, some slight variations can occur as a result of mutations or genetic modifications over time. The arrangement of these bases in a specific order determines the genetic code, which directs the production of proteins and other molecules needed for cellular activities and physiological processes in the body. Therefore, one of the essential things that all of Carlota’s body cells have in common is the presence of DNA as the genetic material. The DNA within each cell of her body is almost identical.

In order to perform a soil microbial count on a sample of soil, you made an initial dilution by mixing 0.1g of soil in 10ml of sterile water then performed a serial dilution. You performed two additional 1:10 dilutions and plated 10 ul of the last two dilutions. By adding 0.1g of soil to 10ml of water, you generated a __initial dilution Which plate counts indicate improper technique took place during your dilution series? Choose a CORRECT answer for BOTH of the statements above
A. You generated a 10-2 initial dilution. Plate counts 171 and 25
B. You generated a 102 initial dilution. Plate counts 165 and 16
C.You generated a 10-initial dilution. Plate counts 252 and 25
D. You gerverated a 10-initial dilution Plate counts 312 and 29
E. You generated a 10-3 initial dilution Plate counts 111 and 11
The correct answer is B. The student generated a 102 initial dilution, and plate counts 165 and 16 indicate that improper technique took place during the dilution series.
To determine the initial dilution, we need to look at the dilution factor of the last two plates. The last two plates were both 1:10 dilutions, which means that they were both diluted by a factor of 10. Therefore, the initial dilution was 10 x 10 x 10 = 10^3 or 1000.
This means that the student added 0.1g of soil to 100ml of sterile water to make the initial dilution. Therefore, answer choices A, C, D, and E are all incorrect because they list incorrect initial dilutions. Only answer choice B lists the correct initial dilution of 10^2, but we also need to consider the plate counts.
Plate counts are the number of colonies that grow on the agar plates, and they can indicate whether there was too much or too little bacteria in the sample. Plate counts that are too high or too low can indicate that the student made a mistake during the dilution series.
In this case, the plate counts are 165 and 16, which is a difference of 10-fold. This means that there was a problem with the dilution series because there should not be such a large difference in the number of colonies between two consecutive dilutions. Therefore, we can conclude that improper technique took place during the dilution series.

all of the following are part of the calvin cycle except all of the following are part of the calvin cycle except all of the above are part of the cycle. regeneration of atp. regeneration of rubp. carbon fixation. synthesis of g3p. note: clicking any button other
During the Calvin cycle, plants fixate CO₂, and use ATP and NADPH to produce sugar molecules G3P, while regenerating RUBP to keep the cycle going. Option A. regeneration of ATP.
What is the Calvin cycle?
The Calvin cycle is the series of chemical reactions that occur during the light-independent phase of photosynthesis.
During the Calvin cycle, sugars or carbohydrates are synthesized.
Carbón dioxide -CO₂- enters the leaves through stomas, and diffuses to the chloroplast stroma. These molecules are used to produce 3-C sugars.
The whole process is impulsed by ATP and NADPH coming from light-dependent reactions.
1) During the carbon fixation phase, the CO₂ molecule combinates with a ribulose-1,5-bisphosphate (5-C molecule) to form 6-C molecules, which will divide into two 3-phosphoglycerate molecules, 3-PGA (3-C molecules).
CO₂ + ribulose-1,5-bisphosphate ⟶ 6-C molecule ⟶ 2 3-PGA
2) During the reduction phase, ATP and NADPH are used to produce the sugar molecule glyceraldehyde-3-phosphate (G3P) from 3-PGA molecules.
NADPH donates its electrons to turn 3-PGA into glyceraldehyde 3-phosphate, G3P.
3-PGA + ATP + NADPH ⟶ G3P + ADP + NADP⁺
3) During the regeneration phase,
some glyceraldehyde 3-phosphate molecules leave the cycle and go to the cytosol to form glucose.Other G3P get recycled to regenerate the RuBP acceptor. This last reaction needs ATP and a series of other reactions.When three CO₂ enter the cycle, 6 G3P are produced. One of them leaves the cycle, and the remaining five are recycled and generate three RuBP.
According to this framework, the only option that is not part of the Calvin cycle is regeneration of ATP. Option A.
