What did Darwin say about finches? Darwin noticed that fruit-eating finches had parrot-like beaks, and that finches that ate insects had narrow, prying beaks. He wrote: “One might really fancy that from an original paucity [scarcity] of birds one species had been taken and modified for different ends.” Why is Daphne Major such a good […]
Is DNA a blueprint?
Is DNA a blueprint? DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce. DNA does this by controlling protein synthesis. Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms. […]
What is molecule Short answer?
What is molecule Short answer? A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than […]
What is another name for straight line motion?
What is another name for straight line motion? The linear motion, also called the Rectilinear Motion can be of two types: Uniform linear motion with constant velocity or zero acceleration. What is type of motion? In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. […]
What are the 3 types of flexibility?
What are the 3 types of flexibility? There are considered to be three main types of stretching methods for muscle flexibility. These are static stretching, dynamic stretching and proprioceptive neuromuscular facilitation (PNF). Is being too flexible bad? By repeatedly pushing past “normal” range, you’re getting micro traumas, which can lead to more serious injury, such […]
Does pressure affect mass flow rate?
Does pressure affect mass flow rate? Doubling the line pressure halves the volumetric flow rate, and decreasing line pressure increases the volumetric flow rate. However, the number of molecules of air that flow (mass flow rate) does not change. What is the relation between pressure and area? The relation between pressure and area is that […]

Can you walk on Pluto?
Can you walk on Pluto? If you were to go off exploring Pluto’s surface, you shouldn’t expect a long trip. Pluto is only about two-thirds as wide as Earth’s moon and has about the same surface area as Russia. Additionally, its gravity is only one-fifteenth that of Earth’s, so you’d only weigh 10 lbs. Are […]
What determines how much load a stream can carry?
What determines how much load a stream can carry? The ability of streams to carry a load is determined by 2 factors: Competence and Capacity. Competence of a stream measures the largest PARTICLES it can transport. A stream’s competence increases with it velocity. The competence of a stream increases 4 times-when the velocity doubles. What […]
What is real matrix?
What is real matrix? A real matrix is a matrix whose elements consist entirely of real numbers. The set of real matrices is sometimes denoted. (Zwillinger 1995, p. 116). SEE ALSO: Complex Matrix, Integer Matrix, Matrix, Random Matrix, Real Number, Square Matrix. What is meant by Hermitian matrix? : a square matrix having the property […]
