A. Turner syndrome.
Turner syndrome is a type of aneoploidy called monosomy, which causes the person to be born with only one X chromosome with no extra Y or X.
The correct answer is ultrasound because the ultrasound is considered use sound waves for the detection of tissue, baby and things like that.
Hope that helps
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.
Relative dating is used to arrange geological events and the rocks are left behind the sequence. Stratigraphy is the method of reading the order.
Explanation:
The Relative dating do not provide actual numerical dates for the rocks. The principle states that in an undisturbed sequence of sediments layers are increased in age from the top to bottom.
The difference between relative and absolute dating is the relative age is age of a rock layer when compared to other layer and Absolute age is the numeric age of layer of rocks or fossils and it is determined by using radiometric dating.
The relative dating techniques are used for climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
