Answer:

Explanation:

DNA directs the synthesis of RNA.

DNA splits into two strands of RNA.

A strand of DNA is used as a template for the formation of RNA.

Two strands of RNA are formed by copying each of the strands of DNA.

The correct answer would be that a strand of DNA is used as a template for the formation of RNA.

Transcription is a process during which RNA is synthesized using DNA as a template. The coding strand of the DNA is utilized as a template for the formation of messenger RNA. During this process, the double helix structure of the DNA is unwound by an enzyme and the coding strand is bound by a short DNA strand at the beginning of a gene while another enzyme adds RNA nucleotide bases to elongate the short strand.

The correct option is C.

What would be the correct sequencing of DNA to match A, T, T, G, C

Marianna [84]

Answer:

Explanation:

The correct sequencing of DNA nucleotides to match A, T, T, G, C is T, A, A, C, G because the nucleotide matches are: Adenine-Thymine, and Guanine-Cytosine. This works both ways, A-T or T-A, and G-C or C-G. The correct sequence therefore is A.

The number of ducks in a pond is equal to the square root of the number of fish, and the number of turtles is equal to the cube

brilliants [131]

Answer:

There are 64 fish, 8 ducks and 4 turtles.

Explanation:

From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.

La ecologia es la ciencia que estudia la materia inerte de un medio natural es falso verdadero

likoan [24]

Answer:

Falso

Explanation:

La ecología es la ciencia que estudia la interacción entre los seres vivos y el ecosistema. Esto incluye la interacción entre todos los factores tanto bióticos, o vivos, como abióticos, no vivos.

Por ejemplo, la ecología podría estudiar la manera en que un venado interactúa con su entorno: cual es su principal fuente de alimento, el rol que juega en el ecosistema, las adaptaciones que ha desarrollado para vivir en dicho entorno, etc.

Debido a que la materia inerte es considerada un factor abiótico o no vivo, esto no correspondería al área de la ecología. Por ende, este enunciado es falso.
