Why does dna contain thymine but rna contains uracil?

Biology
1 answer:
uysha [10]3 years ago
6 0
<span>Thymine is harder to make, but more stable. DNA needs to keep information safe for a long time, so it makes sense to use thymine. But RNA is made and used quickly, and small mistakes don’t matter as much, so the easier to make uracil does the job.</span>

marin [14]
This could be a mutualism rather than a commensal relationship because when<span> "cleaner fish" consume parasites and mucus from the skin of larger fish, they don't only receive food from the relationship, eliminating parasite and such from the large fish, but also they gain protection from predators, thus making the relationship a good example of mutualism, because both parts of the relationship gain something from the relationship itself. </span>

AfilCa [17]

Answer:

Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: <u>esporulación</u>.

Explanation:

En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.

1) How many grams of CO are needed with an excess of Fe2O3 to produce 35.0 g Fe?
satela [25.4K]
1. Moles Fe = 209.7 g/ 55.847 g/mol= 3.75 

The ratio between Fe and CO is 2 : 3 

Moles CO = 3.75 x 3 /2 = 5.63 

<span>Mass CO = 5.63 mol x 28.01 g/mol= 157.7 g

2. </span><span />2Na + 2H2O --> 2NaOH + H2<span>atomic weight of sodium is 23             48.7/23 = 2.12 moles  of sodium 
2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles

so multiply it by Avogadro's number1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen
