The endosymbiotic theory provides an explanation for the evolution of chloroplasts and mitochondria within eukaryotic cells.
This hypothesis posits that eukaryotes developed through a mechanism in which different types of free-living prokaryotes were absorbed into larger prokaryotic cells, eventually transforming into chloroplasts, mitochondria, and other organelles.
A thoracic aortic aneurysm refers to a weakened section located in the upper part of the aorta, the primary artery responsible for supplying blood to the entire body.
Not sure, maybe just look it up online, that should be effective.
The probability of generating plants with white axial flowers is 1/16. Based on the given illustration, all F1 offspring exhibited red axial flowers, indicating that the genes for red and axial traits are dominant over those for white and terminal traits in pea plants. Let's denote the allele for flower color as A (red) and a (white), and for flower position as B (axial) and b (terminal). The genotype of pure-breeding red axial flowers would be AABB, while pure-breeding white terminal flowers are represented as aabb. Crossing these results in F1 genotype AaBb, which shows all red axial flowers. For the F2 generation from AaBb crossed with AaBb, the progeny breakdown is: 9 A_B_ red/axial, 3 A_bb red/terminal, 3 aaB_ white/axial, and 1 aabb white/terminal. Consequently, the chance of generating plants with white axial flowers in the F2 generation is 1/16.
