What factors influence how fast nerve impulses travel? The speed is affected by 3 factors: Temperature – The higher the temperature, the faster the speed. Axon diameter – The larger the diameter, the faster the speed. Myelin sheath – Only vertebrates have a myelin sheath surrounding their neurones. What will increase the length constant of […]
Why is there a Hadley cell?
Why is there a Hadley cell? Hadley Cells are the low-latitude overturning circulations that have air rising at the equator and air sinking at roughly 30° latitude. They are responsible for the trade winds in the Tropics and control low-latitude weather patterns. What are the three cells in the three cell model? The global circulation […]
Can you use 134a gauges with R22?
Can you use 134a gauges with R22? R134a refrigerant is an alternative that contains no chlorine and hence no ozone depletion potential. It’s a greenhouse gas, though, and it doesn’t work as well as R22. Secondly, can I use the same gauges for r22 and r410a? No, you cannot. IS 407C a direct drop in […]
What is the major difference between plant cell and animal cell?
What is the major difference between plant cell and animal cell? A plant cell is larger than an animal cell. The shape of a plant cell is a fixed rectangular shape, whereas an animal cell is mostly round and irregular in shape. Plant cells store energy in the form of scratch while animal cells store […]
Why is it a good idea to start with room temperature water in the calorimeter?
Why is it a good idea to start with room temperature water in the calorimeter? It is a good idea to start with room temperature water in the calorimeter because the room temperature water helps to determine the heating up/cooling down because of the environment as the experiment takes place. Because the calorimeter heat is […]
Is there a number C in the closed interval?
What horizontal force is required if ΜK is zero?
What are periods and groups?
What are periods and groups? All the different elements are arranged in a chart called the periodic table. Here are the main features of the table: the horizontal rows are called periods. the vertical columns are called groups. elements in the same group are similar to each other. What does the group number mean? The […]
Does changing the mass affect acceleration?
Does changing the mass affect acceleration? Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass. How does changing force […]
How long does it take for the blood to circulate through the body?
How long does it take for the blood to circulate through the body? For the blood to circulate throughout the body and back to the heart, it takes about one minute. How fast does your blood circulate through your body? The 5 quarts of blood an adult male continually pumps (4 quarts for women) flow […]
