Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
<u><em>Age group</em></u><em>, </em><u><em>age graph</em></u><em> or </em><u><em>age scale</em></u><em> do not correspond to the population graph where the age and sex structure of a population are expressed.</em>
Answer:
acceleration due to gravity: g= 9 m/s^2
Explanation:
m=2kg
w= 18 n
w=mg
g= w/m
g=18/2
g= 9m/s^2

considered that all terrestrial plant species that exist today have evolved
from Rhyniophyta (a type of spore plants, compiled by the most primitive forms
of vascular). Now terrestrial plants presents by the Moss family, psilotaceae, lycopsids,
class of the Horsetail, fern, gymnosperms and flowering plants. Based on the cladogram, It assumed that the
ancestors of all existing plants are algae, particularly green.</span>
A sizable, distinctive<em> database</em> is created that contains information on 2124 individuals with myelodysplastic syndromes (MDSs) from 4 institutions in Austria and 4 in Germany. This information comprises morphologic, clinical, cytogenetic, and follow-up data. 1084 (52.3%) of the 2072 patients with successfully completed cytogenetic tests had clonal abnormalities. Each patient's chromosomal structural and numerical anomalies were recorded, and the number of additional abnormalities was divided further. As a result, 684 distinct cytogenetic classifications were found. 1286 patients who received only supportive care were used to study how the karyotype affected the disease's natural course. Patients with normal karyotypes had a median life of 53.4 months (n = 612) while those with complicated abnormalities had a median survival of 8.7 months (n = 166).
A total of 13 uncommon abnormalities were found, each with a different prognostic impact: good (+1/+1q, t(1q), t(7q), del(9q), del(12p), chromosome 15 anomalies, t(17q), monosomy 21, trisomy 21, and -X), intermediate (del(11q), chromosome 19 anomalies), or poor (t(5q)). Depending on the chromosomes involved, other anomalies have varying prognostic significance. The karyotype added extra prognostic information for all WHO and French-American-British (FAB) classification system subtypes. Our studies shed fresh light on the importance of rare chromosomal aberrations and particular karyotypic combinations in MDS for prognosis.
<h3>What are
myelodysplastic syndromes?</h3>
A set of malignancies known as myelodysplastic syndromes (also known as myelodysplasia) prevent your blood stem cells from developing into healthy blood cells. Serious diseases include anemia, frequent infections, and bleeding that won't stop can be brought on by myelodysplastic syndromes.
