Where is the olfactory epithelium found? The olfactory epithelium consists of two patches, each with areas of about 5 cm2, located in the roof of the nasal cavities. The epithelium’s surface is defined by a thin perforated bony plate, the cribriform plate, that separates the nasal cavities from the brain. How and why does sniffing […]

Which is an example of radiated heat for cooking? Examples of Radiation Cooking Warming your hands over a fire. Lying in the sun to get warm. Heating up dinner in the microwave. Is Steam a form of radiation? Boiling and steaming are also forms of convection with water or steam acting as the convection fluid….Radiation. […]

When we take DNA from one organism and insert it into another it is called? The term transgenics refers to the process of transferring genetic information from one organism to another. By introducing new genetic material into a cell or individual, a transgenic organism is created that has new characteristics it did not have before. […]

What are the effects of leaching? Leaching removes vital nutrients and micronutrients, such as water-soluble boron, from the soil, causing potential deficiencies in crops. For example, when crops suffer from boron deficiency, they exhibit visual symptoms including: Misshapen, thick, brittle, small leaves. Short stems and a “shrunken” appearance. What could be the result of too […]

What event in the development of the brain leads to synaptic pruning? What event in the development of the brain leads to the need for synaptic pruning? During the fetal period and extending into early childhood, neural networks grow at a rapid rate; in particular, the extensions of neurons and the gaps between neurons (synapses). […]

What are the vessels that lead to the glomeruli? Blood flows into and away from the glomerulus through tiny arteries called arterioles, which reach and leave the glomerulus through the open end of the capsule. What capillaries are found in the cortex of the kidney? At one end of each nephron, in the cortex of […]

What are the two major functions of leukocytes? The two main types of leukocytes are granulocytes and mononuclear leukocytes (agranulocytes). Leukocytes arise from hemopoietic stem cells in the bone marrow. Leukocytes are involved in pathogen recognition, phagocytosis (ingestion of particles), pathogen destruction, inflammation mediation, and antigen presentation. What is the role of leukocytes quizlet? What […]

What is the purpose of petals and sepals? The initial function of sepals is to provide support and protection for a flower bud as they close up around it until it’s ready to bloom. The sepals surround the petals and the reproductive organs inside the flower and protect them from harsh environmental conditions and drying […]

Which represents a metabolic pathway? A metabolic pathway is a step-by-step series of interconnected biochemical reactions that convert a substrate molecule or molecules through a series of metabolic intermediates, eventually yielding a final product or products. Anabolism (building molecules) Catabolism (breaking down molecules) What is basic metabolic pathway? In biochemistry, a metabolic pathway is a […]

What structure acts as a carrier for the foreign DNA? plasmids What is involved in recombinant DNA? Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and […]
