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.

which situation is associated with shear?
A. new rock formations
B. convergent boundaries
C. frequent shallow earthquakes
D. volcanic mountain ranges
Answer:
Frequent shallow earthquakes
Explanation:
Shear is the response of a rock to deformation usually by compressive stress and forms particular textures.
During an earthquake when the earth shakes it produces a super shear earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity.
The mechanisms of shearing depend on the pressure and temperature of the rock and on the rate of shear which the rock is subjected to.

How it is related to forensic science (i.e. provide an example and explain its use in forensic science): DNA is used in forensic science for many applications, one of them is to identify a criminal form the samples of hair, saliva, blood etc. collected from a crime scene.
Explanation:
A macromolecule is a large molecule that is made up of smaller subunits.
DNA is a macromolecule that is made up of nucleic acids.
DNA is most commonly used in forensic science as it is commonly present in the samples such as saliva, hair, blood, etc. that can be easily obtained from a crime scene.
This DNA can then be used to match the person with the help of DNA fingerprinting.
The advantage is that even a small amount of DNA in the samples can be utilized as the technique of polymerase chain reaction (PCR) exists.
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.

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 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.

The hypothalamus, in addition to the cerebral cortex, is in control of emotional responses. the hypothalamus, in addition to the cerebral cortex, is in control of emotional responses.
a. True
b. False
The answer is A; true. Emotions are controlled by the limbic system of the brain that is composed of The amygdala, The hippocampus, Regions of the limbic cortex, and The septal area. These regions work in conjunction with the hypothalamus, thalamus and cerebral cortex in the regulation of feelings such as anger, fear, and pleasure.
Final answer:
The statement is true. The hypothalamus is a critical component of the limbic system, regulating emotional responses by interacting with the cerebral cortex, specifically through connections with the amygdala.
Explanation:
The statement that the hypothalamus, in addition to the cerebral cortex, is in control of emotional responses is true. The hypothalamus plays a crucial role in the limbic system, which is heavily involved in regulating emotions. It receives signals from the amygdala, a structure within the temporal lobe of the cerebral cortex known for its involvement in processing emotions. When emotional responses like fear or anxiety are triggered, the amygdala sends signals to the hypothalamus via the medial forebrain bundle, which can stimulate a fight-or-flight response and influence the release of stress hormones through control of the endocrine system.
The hypothalamus is also responsible for maintaining homeostasis and regulating body functions, such as food and water intake, energy expenditure, and body temperature. Furthermore, its connections with other parts of the brain, including the olfactory cortex and septal nuclei, allow it to regulate emotional states and physiological reactions. The cerebral cortex, particularly its frontal regions, also contributes to the modulation of emotional behaviors through higher cognitive processing and regulation. Therefore, both the hypothalamus and the cerebral cortex have integral roles in the complex network that governs emotional responses.
