The part of the nervous system that arouses a person is the __________ and the part of the nervous system that calms a person is the __________. sympathetic nervous system; parasympathetic nervous system somatic nervous system; central nervous system central nervous system; somatic nervous system parasympathetic nervous system; sympathetic nervous system previous next
The part of the nervous system that arouses a person is the sympathetic nervous system and the part of the nervous system that calms a person is the parasympathetic nervous system.
The Autonomic Nervous System (ANS) is part of the peripheral nervous system (PNS) and is further divided into these two subsystems. The sympathetic nervous system prepares the body for 'fight or flight' responses by increasing heart rate, dilating pupils, and redirecting blood to muscles. On the other hand, the parasympathetic nervous system promotes 'rest and digest' activities by slowing the heart rate, reducing blood pressure, and promoting digestion to help the body recuperate.

Circulatory systems compensate for _____. circulatory systems compensate for _____. the problem of communication systems involving only the nervous system the need to cushion animals from trauma temperature differences between the lungs and the active tissue the slow rate at which diffusion occurs over large distances
The circulatory system compensates for the slow rate at which diffusion occurs over large distances, facilitating efficient transport of materials within the body. Additionally, it also compensates for the limitations of having only the nervous system for communication by disseminating signals broadly to the body via hormones and other messengers.
Explanation:The circulatory system compensates for the slow rate at which diffusion occurs over large distances, amongst other functions. Within the body, materials like oxygen, nutrients, and waste products need to be transported from one region to another. Relying on simple diffusion would be quite inefficient due to the slow rate at which it processes. Therefore, the circulatory system acts as a network of highways, speeding up the transport process significantly.
Furthermore, it's critical to understand that the circulatory system also compensates for the problem of communication systems involving only the nervous system. While the nervous system is crucial for fast and targeted responses, the circulatory system disseminates hormones and other signals broadly to the entire body. It’s a slower communication method, but it affects all parts of the body simultaneously, which can be beneficial for many types of responses.

Which compound that directly provides energy in living cells is being produced in every tube where cellular respiration is occurring?oxygenglucosednaatp?
ATP, or adenosine triphosphate, is the compound produced during cellular respiration that provides direct energy for living cells. It is generated through pathways like glycolysis, the citric acid cycle, and oxidative phosphorylation, with the mitochondria being the primary site of production in eukaryotic cells.
The compound that directly provides energy in living cells and is being produced in every tube where cellular respiration is occurring is adenosine triphosphate (ATP).
During cellular respiration, glucose is oxidized to carbon dioxide, and this process can produce about 30 molecules of ATP from a single molecule of glucose. The three main pathways used to generate ATP in the cells are: glycolysis, the citric acid cycle (also known as the Krebs cycle or TCA cycle), and oxidative phosphorylation. ATP is largely produced in the mitochondria of eukaryotic cells. Oxygen (O₂) is used in oxidative phosphorylation as the terminal electron acceptor in the electron transport chain (ETC), which drives the production of ATP from ADP.
The flow of surface run-off can be controlled by building retaining walls called _____.
The flow of surface run-off can be controlled by building retaining walls called levees, which are key components of flood control systems. In addition to levees, reservoirs collect and store water for various uses, and conservation efforts are important for sustainable water management. Aqueducts and desalination are other methods used to meet freshwater demands.
Explanation:The flow of surface run-off can be controlled by building retaining walls called levees. The purpose of a levee is to prevent the overflow of rivers, lakes, or oceans from flooding adjacent land. Levees are often part of a larger flood control system, which may include dams and reservoirs. By building a levee, water is contained within the riverbanks, and the risk of flooding to surrounding areas is reduced.
Another method of controlling water flow is through the use of sandbags, which can be placed around potential breaches or leaks in levees or embankments as a temporary measure. According to Environmental Biology 207, sandbags can balance a massive body of water by creating a barrier that stops further flow. Reservoirs also play an essential role by collecting water and storing it for use during drier periods, providing benefits such as water supply, hydroelectric power, flood control, and recreation.
Conservation and Sustainable Management of Water
Conservation is crucial for sustainable water management, involving measures like high-efficiency appliances and behavioral changes to reduce water consumption. In areas where water is scarce, desalination can provide fresh water by removing salt from seawater, although this process is expensive and energy-intensive. Aqueducts transfer water from regions where it is abundant to those where it is needed, but they can lead to controversial political issues and environmental impacts on the source regions.
Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and __________.
Bacitracin is an antibiotic that inhibits bacterial cell wall synthesis, causing the cell wall to weaken and eventually leading to cell lysis or the bursting of the cell due to osmotic pressure. This means that the bacitracin is particularly effective against certain types of bacteria, while not harming human cells. It is commonly used in topical ointments due to potential kidney damage from prolonged use.
Explanation:Bacitracin is a peptide antibiotic that inhibits bacterial cell wall synthesis by blocking the movement of peptidoglycan precursors, N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM), across the cell membrane. The cell wall becomes weak due to insufficient peptidoglycan, a major component of the cell wall in bacteria. This results in cell lysis, where the cell bursts due to osmotic pressure because the cell wall can't hold the cell contents.
Bacitracin, like other cell wall synthesis inhibitors such as B-lactams and glycopeptides, exhibits selective toxicity as it targets a feature not present in human cells - peptidoglycan in the cell wall. Antibacterials like bacitracin are effective and popular because they do not harm human cells at the same time as they kill bacterial cells, which makes them particularly potent against Gram-positive bacteria like Staphylococcus and Streptococcus commonly found on the skin. However, it's important to note that prolonged use of bacitracin can lead to kidney damage, so it is often used in combination with other antibiotics like neomycin and polymyxin in topical ointments such as Neosporin.
