Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.

Answer:
120 gramos de CO₂
Explanation:
La ecuación química balanceada para la reacción de combustión del hidrocarburo C₃H₈ (propano) es la siguiente:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Por lo tanto, 1 mol de C₃H₈ produce 3 moles de CO₂. Ahora debemos convertir las moles a gramos utilizando el peso molecular (PM) de cada compuesto:
PM(C₃H₈)= (3 x 12 g/mol) + (8 x 1 g/mol) = 44 g/mol
1 mol C₃H₈ = 1 mol x 44 g/mol = 44 g
PM(CO₂) = 12 g/mol + (16 g/mol x 2) = 44 g/mol
3 mol CO₂ = 3 mol x 44 g/mol = 132 g
Por lo tanto, se producen 132 gramos de CO₂ a partir de 44 gramos de C₃H₈ y la relación estequiométrica es:
3 mol CO₂/1 mol C₃H₈ = 132 g CO₂/44 g C₃H₈
Finalmente, para calcular cuántos gramos de CO₂ se producen al quemar 40 g de C₃H₈, multiplicamos la relación estequiométrica por la masa a quemar:
masa CO₂ producida = 40 g C₃H₈ x 132 g CO₂/44 g C₃H₈= 120 g
Considering that the roots are a form of biological weathering (so/thus) erosion (from/due to) changing weather also (disintegrates/breaks down)the rock.
