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.
Answer:
The sun (abiotic) affects the grass, trees, flowers, etc. by giving off its energy to the plants so they can grow.
Another example is water (abiotic) affects mostly every biotic factor such as humans, plants, or animals because all living things need water to survive.
Answer:
Eccrine glands
Explanation:
There are two to four million sweat glands distributed all over our bodies. The majority of them are “eccrine” sweat glands, which are found in large numbers on the soles of the feet, the palms, the forehead and cheeks, and in the armpits.
#If i'm wrong, i'm sorry
Answer:
Most life would cease to exist
Explanation:
What Consumers have in common is that, they are all living things that live off of hunting and eating to gain energy and survive (without eating/hunting they die).
examples : Cows , Pigs , Horses
