Sexual Protist Reproduction
Some unicellular protists even reproduce sexually, and are able to create gametes, or sex cells, that can fuse together to form a new organism in a process known as syngamy. ... In this process, nuclei from gametes come together and fuse to create a zygotic nucleus.

Answer:
120 gramos de CO₂
Explanation:
La ecuación química balanceada para la combustión del hidrocarburo propano (C₃H₈) es la siguiente:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
Por lo tanto, 1 mol de C₃H₈ produce 3 moles de CO₂. Para convertir las moles a gramos usamos el peso molecular (PM) de cada compuesto:
PM(C₃H₈)= (3 x 12 g/mol C) + (8 x 1 g/mol H) = 44 g/mol
masa de C₃H₈ = 1 mol x 44 g/mol = 44 g
PM(CO₂) = (1 x 12 g/mol C) + (2 x 16 g/mol O) = 44 g/mol
masa de CO₂ = 3 mol x 44 g/mol = 132 g
Ahora podemos ver que se producen 132 gramos de CO₂ (3 moles) a partir de 44 gramos de C₃H₈ (1 mol) ⇒ 132 CO₂/ 44 g C₃H₈
Multiplicamos la relación estequiométrica por la cantidad de propano que tenemos para calcular la cantidad de CO₂ producida:
40 g C₃H₈ x 132 CO₂/ 44 g C₃H₈ = 120 g CO₂
Entonces, se producen 120 gramos de dióxido de carbono al quemar 40 gramos de hidrocarburo C₃H₈.
Answer:
there are two stages of photosynthesis which is the light and dark reaction stage. In the light reaction stage light from the sun is absorbed by the chlorophyll pigments and also split water molecules through a process called photolysis, in this stage light energy is transferred to chemical energy of ATP (adenosine triphosphate) and make reduced NADP (nicotinamide adenosine dinucleotide triphosphate). This stage justifies the second law of thermodynamics which states that the process of energy transformation cannot occur spontaneously unless there is a breakdown of energy from a concentrated form into a dispersed form.
