mash [69]

The potential ecological niche of an organism is its fundamental niche, while the niche an organism actually occupies is its realized niche.

<h3>What is called Ecological Niche?</h3>

Ecology uses the term "niche" to describe a species' role in a community. A species' niche is defined by the physical, environmental, and interactions with other species requirements (such as temperature or topography) (like predation or competition) Ecology defines a niche as the compatibility of a species with a certain environmental circumstance. It explains how an organism or population reacts to the distribution of resources and rivals (for instance, by expanding when resources are abundant and shrinking when predators, parasites, and pathogens are scarce), as well as how it changes those same factors.

1. Classification means the grouping of organisms on the basis of
Vlad1618 [11]

Answer: b) common features.

Explanation: Classification is the way we decide on relationships between groups of organisms, and this is done in several levels in a hierarchy. For example, all plants form a group based on having chlorophyll and being photosynthetic (the plant kingdom), which other kingdoms like animals and fungi do not. Within plants there are divisions, like angiosperms - plants with flowers. The closest relationships are between species in the same genus, plants that have the same kind of flowers and seed, like the Flanders poppy and California poppy.

In eukaryotes, there are two main types of DNA organization present in chromosomes:
kupik [55]

Answer:

The two main types of DNA organization present in chromosomes are the extended DNI and the condensed DNI

Explanation:

In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNA molecule. DNA is intimately associated with two types of proteins: <u><em>histones</em></u>, which are structural proteins, and <em>non-histone</em> proteins that mediate different functions of DNA.

DNA associated with histones is called <u><em>chromatin</em></u>. Histones are responsible for packaging DNA molecule, and the fundamental unit of packaging is known as a <em><u>nucleosome</u></em>. As chromatin must be condensed, nucleosomes generate regular structures between themselves forming a <em><u>chromatinic fiber</u></em>, in which DNA is very condensed. A superior level of condensation is the structural <em><u>ringlet-shaped domain</u></em>. At this level, a chromatinic fiber is folded and a protein is responsible for keeping joined the two regions of DNA that form the ringlet. The next condensation level is the rolling of the ringlet-shaped domain composing the <u><em>chromosome</em></u>. The typical chromosome in the metaphase is formed by <u><em>two chromatids</em></u> joined by a centromere. Each chromatid is composed of a sequence of chromatin ringlets domains. In the interphase, <em>before cellular division</em>, chromatin is in a diffuse, lax, uncondensed state, known as extended DNA. When <em>cellular division</em> is about to happen, chromatin begins to condensate. At the beginning of the <em>prophase</em>, DNA is condensed in a well-defined chromosome formed by two sisters chromatids.
