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
Answer:
There are two-phase of glycolysis preparatory phase and payoff phase. In the preparatory phase, ATP is used therefore it is called the energy investment phase and in the payoff phase, ATP is produced so it is called the energy generation phase.
In preparatory phase 2 ATP is used and it is converted into ADP and in pay off phase 4 ATP is produced from ADP. Therefore by subtracting 2 from 4, we get 2 ATP. Therefore in glycolysis, energy investing and energy harvesting step results into two ATP molecules.

Explanation:
Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).
Answer:
The frequency will be a 3/4 chances on the dominate one being the one that most expresses. (C)
Explanation:
The frequency will be a 3/4 chances on the dominate one being the one that most expresses.
Answer:
The correct answer will be option-D
Explanation:
Pulmonary Surfactant is a complex substance produced by the pneumocytes epithelial II cells in the alveolar sac.
The surfactant is composed of the proteins and lipids which plays a role in keeping alveoli open by reducing the surface tension formed between the air and liquid.
The surfactant act by forming a monolayer surface film which helps reduce the surface tension.
Thus, option-D is the correct answer.
