Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.
Answer:
Tropomyosin blocks myosin binding sights on acting molecules.
Explanation:
It prevents cross-bridge formation, which also prevents muscle contraction
Much of Botswana and Namibia is covered by desert that can support few people. Botswana's climatic pattern is typical of southern Africa, although its rainfall is less than countries further east. As with Namibia, temperatures increase by about 6 degrees for every 100 m you descend. As a result, Namibia's park is hotter, especially those located in the desert. Rainfall is higher in the far North, including Etosha, and the Zambezi Region. Further south the climate is hotter and drier.
Water used by the petroleum industry is injected deep underground and does not return to the hydrological cycle. The correct option is C.
<h3>Water and petroleum industries</h3>
Most of the water used in oil extraction is not returned to the hydrological cycle.
In actual fact, some percentage of the water used in extracting crude oil tends to be a source of pollutants to the freshwater reservoir in the environment.
With irrigation farming, this is not the case. Thus, many citizens will oppose the use of water by the petroleum industry but not irrigation farming.
