Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?
A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes
B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.
D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.
Answers
Answer:
your answer is B. The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

what is a major difference between messenger rna molecules and transfer rna molecules?
Answers
Answer:
1) Messenger RNA molecules contain ribose, and transfer RNA molecules contain deoxyribose.
2) Messenger RNA molecules function in carrying coded information to the ribosomes, and transfer RNA molecules function in carrying amino acids to the ribosomes.
The major difference between messenger RNA molecules and transfer RNA molecules is that messenger RNA carries the genetic information, while tRNA carries the amino acids.
What is RNA?RNA is ribonucleic acid. In the cell, different types of RNA are found, such as mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosome RNA), SnRNA, miRNA, etc. mRNA, or messenger RNA, is formed from DNA. It carries the information of a cell. The three consecutive nucleotides of mRNA make up a codon. An example of a codon is AUG.
tRNA has a cloverleaf-like structure. It has different domains such as the TΨC loop, the DHU loop, the anticodon region, and at the 3' end it is attached to an amino acid. The anticodon of the tRNA reads the codon sequence of the mRNA and attaches the amino acids. For the AUG codon methionine is attached.
Hence, the main difference between the messenger RNA and transfer RNA molecules is that mRNA carries the message of the genetic material, while tRNA carries amino acids to express the genetic material on mRNA.

Explanation:
enzyme + substrate complex =
A substrate is a molecule that an enzyme reacts.
enzymes catalyze chem. reactions with substrates. Substrates transform into 1 or more products. released from " active site," substrate is then able 2 receive another substrate molecule.
Answer:
An enzyme is catalyzing a reaction.
Explanation:
Two substrates bind to the active site of the enzyme. The enzyme catalyzes the reaction (lowers the activation energy needed to complete the reaction), and the result is the final product: two substrates bound together, and an enzyme that can go on to catalyze more reactions.

how many calories are in an average trick-or-treaters halloween stash?
Answers
The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.
Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.
Considering this, in a Halloween stash the calories depend on two factors:
The types of candies or productsThe units of each oneLet's suppose there are 5 units of each of the following candies:
Chocolate barsTaffiesLollypopsCandy cornLet's now calculate the calories
Chocolate bars = 220 calories x 5 units = 1,100 caloriesTaffies = 20 calories x 5 units = 100 caloriesLollypops = 83 calories x 5 units = 415 caloriesCandy corn = 7 calories x 5 = 35 caloriesAdd all the previous results:

Calculate the total resistance (in Ohms) of a light bulb marked 2V and 3A. Do not add units. Leave your answer as a decimal to 2 decimal places.
Answers
The total resistance of a light bulb marked 2V and 3A is 0.67ohms
HOW TO CALCULATE RESISTANCE:
The resistance of a substance can be calculated by using the formula as follows:R = V/I
Where;
R = resistance (in ohms)V = voltage (in volts)I = current (in amperes)According to this question, a light bulb is marked 2V and 3A. The resistance (R) can be calculated as follows:R = 2V ÷ 3A
R = 0.67ohms.
Therefore, the total resistance of a light bulb marked 2V and 3A is 0.67ohms.Learn more at: https://brainly.com/question/8776047?referrer=searchResults
