<h2><u>Full Question:</u></h2>

Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.

<h2><u>Answer</u>:</h2>

Each stage produces ATP, but only the first stage occurs in the cytoplasm.

<h3><u>Explanation</u>:</h3>

Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.

ATP is produced from each astep of cellular respiration. So the correct option is option C.

<span>The Rock Cycle is the process in which rocks are formed, changed, and broken down. An igneous rock can either change into a sedimentary or into a metamorphic rock; just the same that a sedimentary rock can change into an igneous rock or metamorphic rock.

Determine whether each statement correctly describes the myocardial action potential and the pacemaker potential. 1. Because the

Tanzania [10]

Answer:

1. False

2. True

3. True

4. False

Explanation:

In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.

Bill has a perfect cube of an unknown substance. The density of the substance is 3.0 g/cm. He

Gwar [14]

The volume of the cube of unknown substance is $27\ cm^3$ . The length of one side of the cube is 9 cm

<u>Explanation:</u>

As per the formula of mass and density, Mass / Density equals to volume. Therefore as the mass of the cube was given to be 81 g and the density of the cube is known to be 3.0 g/ $\mathrm{cm}^{3}$ ,, to help Bill find out the volume. It is the ratio of mass and density and can be calculated as

$\text {volume}=\frac{\text {mass}}{\text {density}}=\frac{81 g}{3 g / \mathrm{cm}^{3}}=27 \mathrm{cm}^{3}$

As it is a cube, the volume is product of length, breadth, and height. Here, all sides are same as it is the cube.

$volume= length \times breadth \times height$

$27=3 l$

$length of cube's one side, l=\frac{27}{3}=9 \mathrm{cm}$
