I would say that this is true, although there is no absolute answer to this question and one could also find arguments against it.

But, we could set the beginning of global warming to 1940s -that's when the average temperatures started rising. Also 1940s is when the <span> International Union for the Conservation of Nature and Natural Resources was founded - so it's around the same time!</span>

Cytosine makes up 30% of the nucleotides in a sample of DNA from an organism. What percent of the nucleotides in this sample wil
Shtirlitz [24]

Answer:

20%

Explanation:

The four different bases pair together in a way known as complementary pairing. Adenine always pairs with thymine, and cytosine always pairs with guanine.

if adenine makes

The guanine percent is 30. This is because the other 30% of the 60% is cytosine. Getting back to adenine, it always partners up with thymine as i mentioned before, So it would be 20% thymine and 20% adenine, add those portions to the 60% of the other two, mentioned above and you have 100%.

En una isla oceánica aislada hay una especie de pájaros, la
Zinaida [17]

Answer:

La frecuencia del alelo recesivo s es igual a 0.2 (opción b)

Explanation:

<u>Datos disponibles</u>:

  • Plumaje gris es el fenotipo dominante
  • Plumaje con manchas blancas es el fenotipo recesivo
  • S es el alelo dominante para plumaje gris
  • s es el alelo recesivo para plumaje manchado
  • Variedad manchada representa el 4% de la población.

Si ejemplares con ala manchada y genotipo ss representan el 4% de la población, entonces los restantes 96% corresponden a ejemplares grises homocigotas dominantes SS y heterocigotas Ss. Las frecuencias fenotípicas serán:

  • Plumaje gris (SS + Ss) = 96% = 0.96
  • Plumaje manchado (ss) = 4% = 0.04

De acuerdo al equilibrio de Hardy-Winberg, la suma de las frecuencias alélicas equivale a 1, y la suma de las frecuencias genotípicas también equivale a 1.

  • Frecuencia del alelo dominante = p
  • Frecuencia del alelo recesivo = q
  • Frecuencia de genotipo homocigota dominante = p²
  • Frecuencia de genotipo heterocigota = 2xpxq
  • Frecuencia del genotipo homocigota recesivo = q²

Entonces,

  • p + q = 1
  • p² + 2pq + q² = 1

Si la frecuencia genotípica del homocigota recesivo es 0.04, entonces la raíz cuadrada de ese valor es la frecuencia génica del alelo recesivo. Esto es:

  • q² = 0.04
  • q = √0.04 = 0.2

A partir de la ecuación p + q = 1, podemos calcular el valor de p.

p + q = 1

p + 0.2 = 1

p = 1 - 0.2

p = 0.8

Entonces la frecuencia genotípica del homocigota dominante es p²

p² = 0.8² = 0.64

Y la frecuencia genotípica del heterocigota es

2pq = 2 x p x q = 2 x 0.8 x 0.2 = 0.32

Para corroborar esto, la suma de todas las frecuencias genotípicas debe dar uno.

0.64 + 0.32 + 0.04 = 1

What is the atom structure?
Tomtit [17]

Answer:

The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.

Reil [10]
If a woman takes HIV medicines during pregnancy and childbirth and her baby receives HIV medicines for 4 to 6 weeks after birth, the risk of transmitting HIV can be lowered to 2% or less. Most HIV medicines are safe to use during pregnancy, and don't increase the risk of birth defects.

In general, the infected mother should simply stay healthy and intake HIV medicines while she is pregnant.

What is the name of the enzyme complex that forms at the start of transcription?.
blagie [28]

The enzyme complex that forms at the start of transcription is the Rna polymerase-promoter complex.

<h3>What is transcription?</h3>

Transcription is a biological process during which the information on DNA is transcribed into genetic codes in RNA.

The process of transcription occurs in 3 stages, which are:

  • Initiation
  • Elongation
  • Termination

During initiation, an enzyme known as RNA polymerase binds to a region on the DNA to be transcribed. This region is known as the promoter region.

Thus, the binding leads to the formation of RNA polymerase-promoter complex, otherwise known as the initiation complex.
