Answer:

65

Explanation:

The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.

Total guanine + cytosine bases in the segment= 95 + 95 = 190

So, a total of adenine and thymine bases in the DNA segment= 320-190 = 130

Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be= 130/2= 65

What causes the doldrums to be calm winds?
arlik [135]

Earth revolves around the sun, keeping doldrums stationary causes the doldrums to be calm winds. Thus, the correct option is C.

<h3>Why are the doldrums so calm?</h3>

The Intertropical Convergence Zone, also known as the doldrums or calms by sailors due to its constant lack of wind, is the area where the northeast and southeast trade winds meet. It encircles the Earth near the thermal equator, however its exact location changes with the seasons.

The sunlight beams down directly on the area around the equator, the Doldrums are caused by solar radiation from the sun. Instead of blowing horizontally, this heating causes the air to warm and climb straight up. As a result, there is little or no wind for weeks at a time.

De acuerdo con lo anterior llene el siguiente cuadro comparativo señalando con x si las células procariotas o eucariotas posee l
Maurinko [17]

Answer:

El cuadro no está presente pero las diferencias principales entre células eucariotas y procariotas son:

Eucariotas:

Tienen núcleo

Tienen organelas

Tienen Vacuolas

Tienen Citoesqueleto

Tienen Cloroplastos

El ADN está asociado a proteínas

El ADN es lineal

Presentan mitocondrias

Presentan un sistema de endomembranas

Procariotas:

No tienen núcleo

No tienen vacuolas

No tienen cloroplastos

No tienen organelas

El ADN no está asociado a proteínas

El ADN es circular

Presenta mesosomas

Explanation:

Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.
