Answer:
1 monosomy
2 trisomy
3 Down syndrome
4 Turner syndrome
5 non-disjunction
6 metaphase
7 twenty-two
8 largest (chromosome 1)
9 smallest (chromosome 22)
10 karyotype
Explanation:
Non-disjunction during meiosis I or II occur when homologous chromosomes or sister chromatids refuse to separate. This makes the resulting gametes to have too many or too few chromosome numbers in their genomes.
A gamete with too few chromosome number that participates in fertilization with a normal gamete will result in a zygote with abnormally less chromosome number. This situation is referred to as monosomy. Whereas, the fusion of a gamete with too many chromosome number with a normal gamete will result in a zygote with too many chromosome, a situation known as trisomy.
The manifestation of monosomy and trisomy in humans results in Turner and Down syndromes respectively.
Humans have 23 pairs of chromosomes out of which a pair determines maleness or femaleness - the sex chromosome. Other chromosomes are referred to as autosomes. Hence, there are 22 autosome pairs and 1 pair of sex chromosome.
Chromosomes are studied by karyotyping, a process that involves photographing chromosomes at the metaphase stage of the cell cycle, cutting them out, and then arranging them in decreasing order of size.
Mangrove provides shelter to organisms on high coats, they help prevent erosion along coasts and they filter and process pollutants out of the environment
Macro i beleive means small. so macromolecules are pretty much just molecules that are really small
Changes in the blood osmotic pressure would affect the secretion of <em>sweat glands.</em>
Osmoregulation is the passive regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution) to keep the fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis. The higher the osmotic pressure of a solution, the more water tends to move into it.
