Answer:
DNA is double-stranded, while RNA is single-stranded. RNA contains ribose as a sugar, while DNA contains deoxyribose. Also, three of the nitrogenous bases are the same in the two types (adenine, cytosine, and guanine), but DNA contains thymine while RNA contains uracil.
Answer:
C
Explanation:
All living organisms' cell are composed of genetic material in form of DNA. The DNA encodes the information needed for the production of useful products (proteins). The way in which the information is encoded is called the GENETIC CODE. It consists of all the triplet nucleotides in DNA or RNA that encodes an amino acid.
This genetic code is universal i.e. the same genetic code is employed by virtually all living organisms, as a codon does not encode another amino acid in another organism. It is universal that AUG specifies Methionine in all living organisms. This shows that all organism share a common evolutionary history.
Hence, it is possible for an organism to express a gene from another organism since the same genetic code will be used to read the information in the gene.
Answer: 0.05 M
Explanation:
Para responder esta pregunta, hay que tener en cuenta la Ley de Conservación de la Masa. <u>La misma indica que en una reacción química en un sistema cerrado, la masa total de las moléculas que participan permanece constante.</u> Esto significa que la masa utilizada en los reactivos es la misma que la masa de los productos generados.
En este problema, se cuenta con una solución de NaOH (hidróxido de sodio) tiene una molaridad de 0.204 (siendo la molaridad el número de moles por litro de solución) y se utilizan 16.4 mL de dicha solución para agregarla a 50 mL de una solución de H3PO4 (ácido fosfórico).
Entonces, ya que la masa de ambas soluciones no se pierde, podemos utilizar la ecuación de la Ley de Conservación de la Masa:
Concentración inicial x Volumen inicial = Concentración final x Volumen final.
Concentración inicial: 0.204 M
Volumen inicial: 16.4 mL
Concentración final: ?
Volumen final: 50 mL + 16.4 mL = 66.4 mL
Reemplazamos los valores en la ecuación:
0.204 M x 16.4 mL = Concentración final x 66.4 mL
La molaridad de la solución de H3PO4 es de 0.05 M.
Answer:
A genetic disorder that is inherited as a recessive trait is sickle cell anemia.
Explanation:
Sickle cell anemia can be described as a disorder which is caused by a mutation in the hemoglobin beta gene which is found on chromosome number 11. The pattern of inheritance of sickle cell anemia is autosomal recessive which means that both the alleles of the gene shall be recessive for the trait to occur. A person with one recessive allele for the trait will not carry the disease but will be a carrier for the disease.
Answer:
transportation
Explanation:
Transportation (28.2 percent of 2018 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions.
