Fish are cold-blooded or poikilothermic, meaning that their body temperatures vary with the surrounding temperature. During the cold of winter fish become less active. They find little pockets out of the way of fast moving water where they can stay still and conserve energy.
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.
You didn't list any of the following
Color change is the answer because that is a physical change
Answer:
Explanation:
1. From the atmosphere. The CO2 found in the atmosphere including ones expelled by animals during respiration is used in photosynthesis
2. From sunlight. During photosynthesis, plants utilize energy from the sun also known as solar energy converting it into chemical energy
3. The product which is glucose is metabolized in the mitochondria
4. The reduction of CO2 with it acting as an electron acceptor
5. Oxygen is a waste product of oxygenic photosynthesis wherein with oxidation of water, oxygen is produced as a byproduct
