Answer: DNA molecules is packaged into chromosomes which are found in the cell nucleus.

Explanation: Chromosomes are made up of <u>DNA (deoxyribonucleic acid) coiled around proteins called histones that support its structure</u>. In humans cells there are 23 pairs of chromosomes, that makes a total of 46. Twenty-two of those pairs are autosomes while the 23rd pair is called sex chromosomes.

The genetic information is stored in the structure of the DNA, so this molecule is the hereditary material in almost all living organisms. That is why it contains the instructions to construct components of the cell.

The structure that is in the cell's nucleus that contains the genetic information if it is condensed and becomes wrapped and folded with many histone and other proteins, it is called chromosomes.

Humans do have 46 chromosomes, 44 autosomal ones and 2 sex chromosomes.

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.

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.
