Answer:
Excitation is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber. There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential. Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the action potential that excites the muscle fiber. The process begins with a nerve signal stimulating a voltage-gated calcium ion channel to open, allowing the ions to enter the axon terminal. The ions stimulate the release of acetylcholine into the synaptic cleft.

How can the history of Mount Rainier's eruptions help you decide whether hiking around Mount Rainier is safe?
The history of Mount Rainier's eruptions can help you decide whether hiking around Mount Rainier is safe by providing information about the volcano's past activity, eruption patterns, and potential hazards.
The history of Mount Rainier's eruptions provides valuable insights into the volcano's behavior and can help assess the safety of hiking around the area. By studying the volcano's eruption history, scientists and authorities can gather data on the frequency, magnitude, and types of eruptions that have occurred in the past.
This information is crucial for understanding the potential hazards associated with the volcano. For example, if Mount Rainier has a history of frequent and large explosive eruptions, it may indicate a higher level of risk for hikers due to the potential for ashfall, pyroclastic flows, or lahars (volcanic mudflows) that can pose dangers to human life.
Additionally, analyzing the timing and recurrence intervals of past eruptions can help estimate the likelihood of future eruptions. If the volcano has been relatively inactive for an extended period, it may suggest a lower immediate risk for hikers. However, it is essential to consider the potential for future eruptions and monitor any signs of volcanic unrest or changes in activity.
Furthermore, studying the extent and distribution of past volcanic deposits, such as lava flows or ash layers, can help identify areas that are more prone to hazards. This information can be used to establish exclusion zones or restrict access to certain hiking trails that may be closer to potential hazards.
Ultimately, by considering the history of Mount Rainier's eruptions and the associated hazards, authorities can make informed decisions regarding the safety of hiking around the volcano. It is crucial for hikers to stay updated with the latest information from local authorities, volcanic monitoring agencies, and park management to make responsible choices and ensure their safety when exploring the area.

state one adaptation of nephron in the kidney of a desert mammal
Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.

Answer:
As during the civil war, African elephants with tusks were targeted, and the tuskless elephants were left alone. This, in turn, allowed for the tuskless elephant populace to thrive and continuously grow, while the tusked elephants saw a decline as more and more were poached. So, it is only natural that as time progresses, and assuming the circumstances remain constant, that the tusked elephant population will see a negative trend, and inversely the tuskless elephant population will see a positive trend.

Why are terrestrial planets closest to the Sun?
Answer:
The Sun sent out energy and particles in a steady stream, called stellar winds. These winds proved so strong that they blew off mostthe gases of the four planets closest to the Sun, leaving them smaller, with only their rocks and metals intact. That's why they are called rocky, or terrestrial, planets.

A wave has a wavelength, L = 50m, and is traveling in water with a depth of 30m. It is a _________
Group of answer choices
deep water wave
medium water wave
shallow water wave
can't determine
Answer:
The answer to this question is medium water wave
The kind of wave described in the illustration would be a deep water wave.
According to definition, a deep water wave is a wave that occurs at water depths that is more than half the wavelength of the wave.
In this case, the wavelength of the wave is 50 m and the depth of the water is 30 m. Half of the wavelength of the wave would be 25 m.
Thus, the depth of the water is more than half of the wavelength of the wave. This effectively makes the wave a deep water one.
