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
Explanation:
Why are proteins considered polymers but lipids not? Lipids do not align with the definition of a polymer. Proteins are made of long chains of monomers that result in a product with new properties, but lipids are macromolecules that are in fact not made up of tiny components that make up a chain.
B.)Nuclear energy use can decrease soil quality through waste products from mining and production processes.

Please see below
Explanation:
The original primates' key adaptations to their arboreal life way included binocular vision to judge depth and be able to jump to the next brach without falling to a certain death; an opposable thumb, to be able to hold to a branch with a secure grip, and arms longer than legs to swing from branch to branch. This forced them to walk on all fours but it wasn't disadvantageous because they went down to the floor for short periods. During their transformation to humans which resulted from their invading a new habitat in the more open grassy savannas, the opposable thumbs allowed them to use tools, like rocks and sticks which they could use to get food and defend against their enemies. They had to walk upright on two legs, to be able to see afar and locate potential food or predators, so natural selection eventually resulted in longer legs and a modification in the backbone. The significance of this evolutionary history is that modern humans are what they are as a result of a combination of preadaptations from their arboreal ancestors and the new features that resulted from their new habitat on the open ground of the savanna.
<span>Answer : spores, which grow into
a gametophyte<span>
</span><span>A
sporophyte produces spores therefore those plants that have spores is called
sporophyte. A sporophyte is a type of a diploid organism so, which means
that meiosis must occur in order to be able to produce haploid cells containing
half number of chromosomes. Meiosis in sporophyte occurs in an area called
sporangia. The spores that are being created inside sporangia shall be release
into the air. Mitosis is expected to take place on a single haploid spore in
order to be a multicellular gametophyte.</span></span>
