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
Answer:
The change in color in the flowers is because the plant has absorbed the dyed water. After some hours, we can see that the water has ascended through the roots, the stem and reached the flower petals. We can see the water's path till it evaporates in a process called transpiration, which returns water to the atmosphere.
Explanation:
Plants absorb water and other nutrients so that they can live. When we add ink into the water, we can see the water's path from the roots, up the stem, the leaves, and the flowers. In the flowers, the water evaporates through the stomata. We call this process transpiration. The ink allows us to see that the water was in the petals, but it evaporates, leaving behind the ink. As water evaporates, the plant drinks more, which results in a more intense color in the petals.
Answer:
4) biological preparedness
Explanation:
Biological preparedness is a phenomenon that humans and animals have developed over time as a survival mechanism. It explains the tendency of humans and animals to form associations between dangers and some stimuli. In this case, humans tend to associate snakes with danger than flowers to danger. This tendency of humans to associate snakes with danger has made humans, according to evolutionary perspective, to fear and avoid snakes. And so, became a trait for adaptation for humans’ survival.
This is an example of Nuclear Technology.
In nuclear technology, the atomic nuclei of radioactive fuel undergo nuclear reaction.
This means that the radioactive fuel undergoes nuclear fission (atomic nuclei separates or splits) or fusion (atomic nuclei fuses or joins).
Nuclear technology then generates atomic energy and releases it in the form of electricity.
