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 of the following events encouraged Somali fishers to become modern-day pirates?
A. The Somali government's inability to protect its resources
B. Attack
s by international pirates on Somali fishers
C. The illegal entry of cargo ships into Somali waters
D. Legal fishing in Somali waters by international fishers
Answer:
A.
Explanation:
Legal fishing in Somali waters by international fishers encouraged Somali fishers to become modern-day pirates. Therefore, option (D) is correct.
Who were Somali fishers?Somali fishers are individuals who work in the fishing industry in Somalia, a country located in the Horn of Africa. Due to a lack of effective government control and the effects of overfishing by foreign fleets, Somali fishers have faced significant challenges in recent years. The depletion of fish stocks in Somali waters has made it difficult for local fishers to make a living, leading some to turn to piracy as a means of survival.
In addition, the activities of international ships, including illegal fishing and dumping of toxic waste, have further damaged the environment and the livelihoods of local fishers. The issue of Somali piracy has become a complex problem involving economic, environmental, and political factors.

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.

Continuous cell lines differ from primary cell lines in that question 12 options:
a.viruses can be grown in continuous cell lines.
b.continuous cell lines can be maintained through an indefinite number of generations.
c.continuous cell lines always have to be reisolated from animal tissues.
d.continuous cell lines are derived from primary cell lines.
e.continuous cell lines are from human embryos.
Continuous cell lines can be propagated indefinitely, while primary cell lines have a limited lifespan.
Option (b) is correct.
Continuous cell lines differ from primary cell lines in that they can be maintained and propagated through an indefinite number of generations, whereas primary cell lines have a limited lifespan and eventually undergo senescence or cell death.
Continuous cell lines are derived from primary cell lines through a process called immortalization, where they acquire the ability to divide indefinitely. These cell lines are often used in research laboratories and biotechnology applications because of their ability to provide a continuous and consistent source of cells.
Unlike primary cell lines, continuous cell lines do not need to be reisolated from animal tissues repeatedly. They can be cultured in the laboratory under specific conditions, and they are widely used for studying cell biology, drug testing, vaccine development, and viral propagation, among other applications.

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.
