Ap Biology: Chapter 8

Rough Endoplasmic Reticulum – A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing and transport of proteins. Covered in ribosomes.
alternation of generations – A life cycle found in plants in which it goes through alternating haploid and diploid stages.
Why are leaves only 4-5 cells thick – no cell is far from light and CO2
Steps of scientific method – Observation Hypothesis Theory Scientific Law
Digestive System – mouth → oesophagus → stomach → liver → pancreas → small intestine → large intestine → rectum → anus
amphibian – Member of the tetrapod class Amphibia. Amphibians include frogs, toads, and salamanders.
prophase – the first phase of mitosis; centromeres migrate to poles in the cytoplasm and chromosomes develop from chromatin material in the nucleus
Exons – the sections of the mRNA molecule that contain the instructions for the protein
Pterosaurs – Winged reptiles that lived during the time of dinosaurs.
karyotype – the figure produced when the chromosomes of a species during metaphase are arranged according to their homologous pairs
The upper, wing-shaped portion of the pelvic bone is called the
mycorrhizae – (singular, mycorrhiza) A close association of plant roots and fungi that is beneficial to both partners.
recessive genes show when the person is – homozygous recessive
phagocyte – A white blood cell (for example, a neutrophil or a monocyte) that engulfs bacteria, foreign proteins, and the remains of dead body cells.
The upper, wing-shаped pоrtiоn оf the pelvic bone is cаlled the
sunlight – Source of energy on Earth
Conclusion – The logical interpretation of the results of a test or experiment – In science, it expresses either support or rejection of the hypothesis.
evolution is the accumulation of differences between groups which can lead to the formation of new species, usually a result of diffusion of the same species to different and isolated environments which blocks the gene flow among the distinct populations allowing differentiated fixation of characteristics through genetic drift and natural selection.
