Which cellular dysfunction is responsible for the manifestations of cystic fibrosis? abnormal chloride channel proteins allow increased sodium and water reabsorption. thickened peripheral proteins bind with phospholipids to block water absorption. extra integral proteins develop and block cellular fluid transport. transmembrane proteins transport additional water into cells?

Abnormal chloride channel proteins allow increased sodium and water reabsorption

Explanation:

Persons with cystic fibrosis have a defective CFTR gene. The causes the abnormal development of the cystic fibrosis transmembrane conductance regulator protein that is responsible for balancing water and salts across the membrane especially in epithelial cells that produce mucus and sweat and secretory enzymes. This causes the production of abnormally thick secretions that block the ducts.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
