In what specific situations would you use a light microscope? A light microscope is used to view the details of the surface of a cell as it cannot be viewed in detail by the transmission microscope. b. A light microscope allows visualization of small living cells, which have been stained and cannot be viewed by […]
What happens if you dont shear a sheep?
What happens if you dont shear a sheep? Unlike other animals, most sheep are unable to shed. If a sheep goes too long without being shorn, a number of problems occur. This can cause sheep to become overheated and die. Urine, feces and other materials become trapped in the wool, attracting flies, maggots and other […]
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 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 […]
What happens in the body negative feedback temperature control system?
What happens in the body negative feedback temperature control system? Negative feedback is a vital control mechanism for the body’s homeostasis. When body temperature drops, the hypothalamus initiates several physiological responses to increase heat production and conserve heat: Narrowing of surface blood vessels (vasoconstriction) decreases the flow of heat to the skin. How do you […]
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 […]
