Pregnancy begins when a sperm fertilizes an egg. This usually occurs in the 2 weeks following the first day of the most recent menstrual period. In the first few weeks of pregnancy, a woman may have no symptoms. Some can sense that they are pregnant, but most do not suspectRead More →
Fossilization, or taphonomy, is the process that occurs when plant and animal remains are preserved in sedimentary rock. Fossilization occurs after an organism dies and only affects hard body parts, such as bones and shells. … Over time, the sediment hardens, and the shell dissolves away, leaving a mold ofRead More →
Post-translational modifications take place in the ER and include folding, glycosylation, multimeric protein assembly and proteolytic cleavage leading to protein maturation and activation. They take place as soon as the growing peptide emerges in the ER and is exposed to modifying enzymes. What causes protein modification? Abstract. Degenerative protein modificationsRead More →
Biological Contamination Dust. Raw meat. The air. The human body. Pets and pests. Kitchen clothes. What is an example of biological contamination? Biological contaminants include bacteria, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen. There are many sources of these pollutants. … Standing water, water-damaged materialsRead More →
Left-sided heart failure is related to pulmonary congestion. The left side of the heart receives oxygen-rich blood from the lungs. When the left side is not pumping correctly, blood backs up in the blood vessels of the lungs — pulmonary edema. How do you find pulmonary edema? Tests that mayRead More →
During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. … Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. Does cytokinesis occur inRead More →
Photosynthesis, a plant’s internal process that converts light energy into food, takes place mostly in the leaves of plants. Plants and trees utilize specialized structures to conduct the chemical reactions necessary to transform sunlight into chemicals the plant can use. Where does photosynthesis occur in the chloroplast? Photosynthesis occurs inRead More →
Spermatogenesis. Spermatogenesis occurs in the wall of the seminiferous tubules, with stem cells at the periphery of the tube and the spermatozoa at the lumen of the tube. Immediately under the capsule of the tubule are diploid, undifferentiated cells. Where does gametogenesis take place? Gametogenesis is the process by whichRead More →
Myelin is made by two different types of support cells. In the central nervous system (CNS) — the brain and spinal cord — cells called oligodendrocytes wrap their branch-like extensions around axons to create a myelin sheath. In the nerves outside of the spinal cord, Schwann cells produce myelin. AreRead More →
