A) Mitochondria.
B) Nuclei.
C) Ribosomes.
D) Vacuoles
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the MITOCHONDRIA. These organelles (mitochondria) are the energy centres of the cell.
Cellular respiration is a series of metabolic reactions by which the cell produces energy in the form of ATP by using the energy stored in the chemical bond of simple carbohydrates and oxygen.
Cellular respiration has three stages: glycolysis, the citric cycle and oxidative phosphorylation.
Glycolysis occurs in the cytoplasm, whereas the citric cycle and oxidative phosphorylation take place in the mitochondria.

A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.

the allowance for uncollectible accounts is a contra account to
The allowance for uncollectible accounts refers to a company that accepts the risk of giving credits to those who may not pay it back. These debts are written off as uncollectable and are a contra asset on the balance reports.
Uncollectable accounts are also often referred to as doubtful accounts. This implies that the company that is giving the credit accepts the possibility that this entity may not return the money. This results in a loss for the company as is recorded as a contra asset on the balance sheets for the company. Some ways for companies to control this loss are:
Establishing requirements for creditsUsing credit collectors to claim large debtsLimiting amount of loss permitted based on historical and industry records.A contra asset or contra account is an account on a companies balance sheet that decreases the balance of certain assets. Contra derives from Latin and means against. Meaning this is an account that goes against the positive balance of the company, it subtracts from the companies earnings.

Students created note cards comparing characteristics of eukaryotic and prokaryotic cells.
Which set of note cards most accurately compares these cells?
Given what we know about Eukaryotic and Prokaryotic cells, we can confirm that the note card labeled "F" is the one that best compares these two cell types.
Eukaryotic and Prokaryotic cells have many differences to discuss, the ones mentioned in note cards, however, are:
The presence of membranes surrounding organelleThe location of the DNA for each cellProkaryotic cells are cells that lack any organelle or nucleus. This is due to the absence of membranes, which are needed to maintain the structure of the organelle. Due to the lack of membranes and therefore of a nucleus, the DNA of these cells can be found floating in the cytoplasm. Table F is the only one that accurately represents these traits.
Eukaryotic cells, on the other hand, are those that do possess membranes. The presence of membranes allows the eukaryotic cells to have a nucleus that can contain their DNA. This cell type is that of most multicellular organisms, whist the prokaryotic are known most commonly as bacteria. Once again, table F is the one that best represents this data.

The tails of the cell membrane are ____________ while the phosphate heads are ___________.
Hydrophilic, Hydrophobic
Hydrophobic, Hydrophilic
Flexible, Hydrophobic
Water Loving, Flexible
Explanation:
The tails of the cell membrane are __hydrophobic__ while the phosphate heads are __hydrophilic__.
I hope the following image helps to further explain the answer.
The tails of the cell membrane are hydrophobic while the phosphate heads are hydrophilic. The correct option is B.
What is the structure of cell membrane?The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure. These compartments are the inside and outside of the cell in the case of the plasma membrane.
The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The membrane of the cell is composed of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
The heads (phosphate) are polar, whereas the tails (lipid) are non-polar. The heads, which form the outer as well as inner linings, seem to be "hydrophilic" (love water), whereas the tails, which face the cell membrane's interior, are "hydrophobic" (water fearing).
Thus, the correct option is B.

Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?
Although I could not locate the options in order to provide a ranking, I can offer the insight that a hypertonic saline solution will be the most effective form of treatment.
I believe you are referring to the full case study which says :
"Your goal is to stop Clark's seizures by restoring equilibrium between the blood and the matrix. Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?"
A hypertonic saline solution is used to draw water out of cells by creating an increased concentration of solute in the blood, forcing the water out of the cell through osmosis.
Clark's seizures may be caused by Increased solute concentrations in the brain which forces water from blood to move into the brain, thus increasing the matrix pressure. This then causes the neurons to fire at an increased rate and leads to the seizures Clark was experiencing.
Hypertonic saline can be used to increase solute concentrations, in this case, Sodium, in the blood which forces water to move back into veins. Thus returning Clark to a balanced level of blood and matrix water levels, and may reduce his likelihood of seizures.
