Respuesta:

d. Ninguno tiene la razón

Explicación:

Para convertir masa a moles, necesitamos la masa molar de cada sustancia.

Fernando (58.85 g Fe)

La masa molar de Fe es 55.85 g/mol.

58.85 g × 1 mol/55.85 g = 1.054 mol

Jacqueline (23.05 g Na)

La masa molar de Na es 22.99 g/mol.

23.05 g × 1 mol/22.99 g = 1.003 mol

Carlos (35.45 g Cl)

La masa molar de Cl es 35.45 g/mol.

35.45 g × 1 mol/35.45 g = 1.000 mol

Paola (27.0 g Al)

La masa molar de Al es 26.98 g/mol.

27.0 g × 1 mol/26.98 g = 1.00 mol

Flauer [41]

Answer:

Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.

Example: Fertilized egg cells.

Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.

Example: Blastocyst cells.

Multipotent Stem Cells - They can only differentiate into closely related cells.

Example: Blood stem cell

Unipotent Stem Cells - They can only produce their type of cell.

Example: Skin stem cells (which can only become a new skin stem cell).

How does each animals specific environmental needs (food, water, shelter) affect its living conditions in a zoo?
777dan777 [17]

Answer:

in many ways

Explanation:

if the animal does not receive the same nutrition that it would in the wild, the animal will become weaker. If the climate of the zoo is very different than the animals natural habitat, they will struggle to maintain homeostasis. If a dolphin, for example, is in a tank that is too small, it will struggle to grow and develop.
