Answer:
Pluto
Explanation:
Orcus is a plutino, a trans-Neptunian object that is locked in a 2:3 resonance with the ice giant Neptune, making two revolutions around the sun to every three of Neptunes. This is much as pluto, except that the phase of Orcus's orbit is opposite from Pluto's: Orcus is at aphelion when pluto is at aphelion when Pluto is at perihelion and vice versa. This was a major consideration in selecting its name, as deity Orcus was the Etruscan equivalent of the Roman Pluto, and later becamean alternate name for Pluto
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.
Answer:
Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Explanation:
Cancer is unchecked cell growth. As a mass of cancerous cells grows, it can develop into a tumor.
CO2 is a normal waste that normally diffuse across placenta from embryo to the mother.
