41 Calories is less than 410 kcal.
To clarify: 1 kcal is equal to 1,000 calories, and in dietary terms, "Calories" (with an uppercase "C") refers to kcal. Therefore, 41 Calories is equal to 41 kcal, which is indeed less than 410 kcal.

During cellular respiration, energy is released. What would a model need to show to accurately demonstrate that matter is rearranged, and energy is conserved in the process?(1 point)
Responses
Glucose and oxygen breaking into carbon dioxide and water, showing that the mass remains the same and energy is released.

The model would need to show glucose and oxygen breaking into carbon dioxide and water, showing that the mass remains the same and energy is released. This accurately demonstrates the concept of matter being rearranged during the process of cellular respiration and illustrates the conservation of energy.

Which is true about pluripotent and multipotent cells?(1 point)
Responses
A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.
A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.
Multipotent cells make up most adult somatic cells, but they are not stem cells like pluripotent cells.
Multipotent cells make up most adult somatic cells, but they are not stem cells like pluripotent cells.
A multipotent cell can differentiate into any cell type within the body, but a pluripotent cell cannot.
A multipotent cell can differentiate into any cell type within the body, but a pluripotent cell cannot.
Both multipotent and pluripotent cells can differentiate into any cell type within the body, but only pluripotent cells can become extraembryonic.

Both multipotent and pluripotent cells can differentiate into any cell type within the body, but only pluripotent cells can become extraembryonic.
The true statement is: A multipotent cell can become many different types of specialized cells within a tissue or organ, but it is more limited than a pluripotent cell.
Pluripotent cells can differentiate into almost any cell type in the body, while multipotent cells are restricted to becoming a limited range of cells within a specific tissue or organ.
