Answer:
Each organ system performs specific functions for the body, and each organ system is typically studied independently. However, the organ systems also work together to help the body maintain homeostasis.
For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved. The digestive system also plays a role with variable water absorption. Water can be lost through the integumentary and respiratory systems, but that loss is not directly involved in maintaining body fluids and is usually associated with other homeostatic mechanisms.
Similarly, the cardiovascular, integumentary, respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)
Answer:
b. characterized by a lucid interval immediately after injury.
Explanation:
Epidural bleeding is the accumulation of blood between the dura (membrane lining the brain) and the skull. This bruise is typically caused by an acute head trauma that ruptures the middle meningeal artery. This bleeding is characterized by a lucid interval immediately after an injury to this region.
This bleeding has its most frequent location at the temporal lobe level, between the bone and the dura mater. It is due to rupture of the middle meningeal artery, usually by a temporal bone fracture. The artery runs on the outer surface of the dura, housed in a groove in the inner bone board. The fracture may clamp or cut the artery, leading to a bruise.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), from animals to plants and microorganisms. Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.
Answer:
Between silver and aluminum wires of same thickness and length, silver will offer lesser resistance.
Explanation:
Aluminum will offer higher resistance than silver (both having same thickness and length).
Silver has lesser resistivity than aluminum.
Resistivity is directly proportional to resistance.
Thus, between to wires of distinct materials, one with higher resistivity will offer greater resistance.
