6. nuclear envelope
7. chromosomes
8. cilia
9. Rough endoplasmic reticulum
10. Golgi apparatus
11. citoesqueleton
12. vesicles
13. ribosomes
14. smooth endoplasmic reticulum
15. cell membrane
Explanation:
Mitochondria are the energy centers of the cell that work to produce ATP. Centrioles are organelles composed of tubulin protein that organize microtubules that serve as the cell's skeletal system. Lysosomes are vesicles that contain hydrolytic enzymes. The cytosol is a thick solution inside the cell which is enclosed by the cell membrane. The nucleolus is an organelle inside the cell nucleus involved in the transcription of ribosomal RNAs. The nuclear envelope is a membrane that surrounds the cell nucleus (in eukaryotic organisms). Chromosomes are linear molecules composed of chromatin (DNA + histone proteins) which contain the genetic material of the cells. The cilia are organelles found on eukaryotic cells involved in the movement of the cell. The rough endoplasmic reticulum is an organelle whose function is the processing of proteins synthesized in the ribosomes, while the smooth endoplasmic reticulum functions in lipid synthesis. The Golgi apparatus is an organelle involved in transporting and packaging proteins and lipids. The cytoskeleton is a dynamic network of protein filaments that act as the skeleton of the cells. Vesicles are membrane-bound structures that transport substances in the cell. The cell membrane is a lipid bilayer that acts to transport nutrients into the cell and waste products out of the cell.
Answer:
No, observed and expected frequencies are different.
Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062
Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014
Explanation:
Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139
Frequency of recessive allele s (q) = square root of 0.0139 = 0.12
Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88
Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014
Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774
Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211
Observed frequencies in population 2
Observed frequency of homozygous dominant genotype = 308 / 549 =0.56
Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375
Observed frequency of homozygous recessive genotype = 34 / 549 =0.062
Observed frequencies do not match with expected frequencies.
From mouth/nose, the air passes to the trachea (the wind pipe), there it enters (sequentially) the bronchi, bronchioles (small pipe-like structures), alveoli (widened empty sacs), the walls of which are in close contact with the blood vessels which contain the RBCs, which in turn contain the protein--hemoglobin, which binds to the oxygen present in the freshly inhaled air, and loses the carbondioide present DISSOLVED in the blood. This bound oxygen goes to the heart (of course along with the RBCs in the blood), from there to the smaller and smaller arteries, then to the capillaries, where again oxygen is lost to the surrounding tissue fluid, from where the cells collect oxygen by simple diffusion, and lose carbon dioxide, which gets dissolved in the water present in the blood.
From here the blood, with hemoglobin poorer in oxygen, and richer again in carbondioxide goes to the venules, and veins (capillaries continue as venules), which become successively larger to become superior and inferior vena cava and enter the right atrium, and then from there the blood again goes to the lungs and comes in contact with fresh air in the alveoli.
