Answer:

No, there are no differences

Explanation:

Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide chains that interact together in order to form a double helix. This molecule (DNA) carries the genetic instructions that make each species unique. In DNA, each polynucleotide chain is composed of nucleotide monomers: a nucleotide is composed of a deoxyribose sugar attached to a phosphate group and one nitrogen-containing base (i.e., adenine, thymine, guanine and cytosine). This basic structure is the same among different species, and, therefore, genetic differences between different groups (in this case, animals, plants, and bacteria) are caused by differences in the nucleotide-base sequences of their DNA molecules.

What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP
Nady [450]

The given question is incomplete, the complete question is:

During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions. Condition Rate of carbon dioxide produced (mL/min) Germinating peas, 10ºC 0.01 Germinating peas, 20ºC 0.02 What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production. Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production. Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC. The rate of cellular respiration cannot be measured without knowing the rate of ATP production.

Answer:

The correct statement is that at 20 degree C, the germinating peas exhibits a higher rate of cellular respiration in comparison to the germinating peas at 10 degree C.

Explanation:

The process of respiration results in the production of carbon dioxide, respiration refers to a chemical reaction that generates water, carbon dioxide, and energy by undergoing oxidation of the glucose molecules. This phenomenon plays an essential role in the life of the organisms for obtaining energy from the food they consume to perform daily activities.  

From the question, it is evident that the peas, which were germinating at 20 degrees C exhibit a higher rate of cellular respiration as they are generating 0.02 milliliters of carbon dioxide in a minute, while on the other hand, the germinating peas at 10 degrees C are giving rise to 0.01 milliliters of carbon dioxide in a minute.

I am Lyosha [343]

Answer:

1 oxygen atom and 1 hydrogen atom from the glucose molecule, and 1 oxygen atom from the fructose molecule were taken to make the water molecule. The rest of the atoms in the glucose and fructose molecules (glucose: 6 carbon, 11 hydrogen, 5 oxygen. Fructose: 6 carbon, 12 hydrogen, 5 oxygen.) combine to make sucrose(12 carbon, 22 hydrogen, 11 oxygen).
