Answer:

Chemical reactions convert reactants into products. In nonliving systems, the presence of a(n) catalyst allows the reaction to proceed very quickly and have a lower activation energy. In living systems, this functions is carried out by proteins called enzymes.

Savatey [412]
Compounds that inhibit receptors by preventing the natural messenger from binding are known as antagonist.    

 Antagonists are molecules that will block the binding of the natural messenger at a receptor molecule. As a result, the signal which is usually produced by a receptor-messenger coupling will be inhibited. <span>An antagonist can be a drug that blocks a biological response by binding to and blocking a receptor.</span>

Un objeto posee una energía cinética de 300J, este mismo se ubica a 4m de altura y su masa corresponde a 10Kg. ¿Cuál es su energ
Arturiano [62]

Answer: 692 J

Explanation:

La energía mecánica es la energía que se utiliza para realizar un trabajo determinado y se calcula con la suma de la energía cinética y la energía potencial de un objeto. En otras palabras, describe la energía de un objeto debido a su movimiento, posición, o ambos.

<u>La energía cinética es el trabajo necesario para acelerar un cuerpo desde el reposo hasta su velocidad final</u>. Entonces, es la energía que posee un cuerpo debido a su movimiento. Cuando gana energía durante la aceleración, el cuerpo mantiene la energía cinética a menos que su velocidad cambie, y el cuerpo realiza la misma cantidad de trabajo al desacelerar desde su velocidad actual hasta un estado de reposo. Por otro lado, <u>la energía potencial es la energía que posee un objeto debido a su posición con respecto a otros objetos.</u> Los tipos más comunes de energía potencial incluyen a la energía potencial gravitacional de un objeto que depende de su distancia al centro de masa de otro objeto (La Tierra), la energía potencial elástica de un muelle o resorte extendido y la energía potencial eléctrica de una carga en un campo eléctrico.

La unidad de energía en el Sistema Internacional de Unidades (SI) es el julio, que tiene el símbolo J.

La energía mecánica se calcula de la siguiente manera (tener en cuenta que la aceleración de la gravedad es un dato tabulado de 9,8m/s^2):

Energía mecánica = Energía cinética + Energía potencial

Energía mecánica = (1/2 * masa * velocidad^2) + (masa * gravedad * altura)

Energía mecánica = 300 J + (10kg * 9,8m/s^2 * 4m)

Energía mecánica  = 300 J + 392 J = 692 J

Fiesta28 [93]

RNA interference has potential applications in biotechnology and medicine, except for treating diseases characterized by genes that are not expressed.

<h3>What is RNA interference?</h3>

RNA interference (RNAi) or post-transcriptional gene silencing (PTGS) is a conserved biological response to double-stranded RNA that confers resistance to both endogenous parasites and exogenous pathogen nucleic acids, encoding proteins regulates the expression of genes.  

<h3>What are the advantages of RNAi?</h3>
  • RNA interference is a natural process involved in the regulation of protein synthesis and immunity.
  • One of the advantages of RNAi technology is the rapid development of effective targeted drugs to control tumor growth. Therefore, cancer is one of the prime targets for RNAi-based therapy due to its high relationship with gene expression and cell proliferation.
