Artificial selection is the idea that humans and other organisms have control over this and natural selection is the idea that humans and other organisms have no control and it merely just takes place.
Hi there!
The answer to this question is B.
Hope this helps!
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.

3) store hereditary information
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, as on units called chromosomes. ATP functions as a precursor molecule for more complex nucleotides.
Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
