Cyanobacteria are the major force of the Great Oxygenation Event around 2.35 billion years ago. The organisms that evolved photosynthesis changed the composition of the atmosphere to mainly oxygen. This changed the dynamic of life on earth by allowing organisms to also exist on land. This is because it was possible for ozone to form and reduce the lethal UV rays from the sun reaching the earth's surface to destroy genetic material.
Inner surface of the small intestine is not flat, but thrown into circular folds, which not only increase surface area, but aid in mixing the ingesta by acting as baffles. Villi: the mucosa forms multitudes of projections which protrude into the lumen and are covered with epithelial cells.
Given that a cell is undergoing meiosis, at the end of meiosis I, its number of chromosomes would be in half. Provided in the question that the cell in G1 has 40 chromosomes, at the end of meiosis I, there will be 20 chromosomes in each daughter cell. And each chromosome has two sister chromatids, then there will be 40 sister chromatids in each daughter cell.
