Does the brain sit in fluid? Being surrounded by CSF helps the brain float inside the skull, like a buoy in water. Because the brain is surrounded by fluid, it floats like it weighs only 2% of what it really does. If the brain did not have CSF to float in, it would sit on […]
How do I find carrier frequency?
How do I find carrier frequency? The carrier frequency can then be calculated as 2X99/100×1/100 which approximates to 1 in 50. Thus a rough approximation of the carrier frequency can be obtained by doubling the square root of the disease incidence. For an X-linked disorder the frequency of affected males equals the frequency of the […]

How do I count positive and negative numbers in Excel?
How do I count positive and negative numbers in Excel? Here, the COUNTIF function can help you quickly to count how many positive numbers or negative numbers in a range. Notes: 1. If you want to count the number of negative values only, please apply this formula =COUNTIF($A$1:$D$7,”<0″). Can Excel Count negative numbers? To count […]
What is the characteristic of compound?
What is the characteristic of compound? Characteristics of a compound The properties of a compound are different from the properties of its constituents. Formation of a compound is generally accompanied by evolution of energy in the form of heat or light. A compound has a fixed melting point and boiling point. A compound is always […]

What are the two main types of energy?
What are the two main types of energy? Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy. What are the two types of mechanical energy? There are two main types of mechanical energy. They are motion energy and stored mechanical energy. Motion energy: This is the energy […]
What are examples of fast chemical reactions?
What are examples of fast chemical reactions? Chemical reactions that complete in a very short time, such as less than 10 -6 seconds, they are called fast reactions. Examples: Magnesium ribbon is burnt in the flame of Bunsen burner; it quickly gets combusted with a noticeable spark. Similarly, a neutralization reaction between acids and bases […]
Can dog whistles damage human ears?
Can dog whistles damage human ears? Some sounds (such as gunfire or standing next to a helicopter) are so loud (120-160 dB), that any brief exposure to them without wearing earmuffs or earplugs can damage hearing. (This means that the dog whistles are at a very high frequency but that they do not move the […]
What is CP CV called?
What is CP CV called? The Cp/Cv ratio is also called the heat capacity ratio. (i.e.) Heat Capacity ratio = Cp/Cv = Heat capacity at constant pressure/ Heat capacity at constant volume. How do you calculate CP in thermodynamics? cp = cv + R The specific heat constants for constant pressure and constant volume processes […]
