Are good looks inherited? This allowed the researchers to look at the genetic component of attractiveness. They found that attractiveness is hereditary, passed on from father to son. Previous research has shown that females that mate with attractive males do not produce more offspring than those mating with less desirable males. Why do some families […]
What are the two groups into which the Jovian planets are classified?
What are the two groups into which the Jovian planets are classified? Due to difference in their structure and composition, the four gas giants are often differentiated, with Jupiter and Saturn being classified as “gas giants” while Uranus and Neptune are “ice giants”. How do you classify planets? There are four main categories of classifications […]
Where is diffusion found in the body?
Where is diffusion found in the body? The rate of diffusion is effected by a number of factors which include temperature, concentration and molecular mass. Diffusion is an important process within the human body and is essential to the transport of molecules within a number of organs including the lungs, kidneys, stomach and eyes. What […]
How does the number of electrons affect the properties of an atom?
How does the number of electrons affect the properties of an atom? The number of electrons, in turn, determines the chemical properties of the atom. The electrons arrange themselves in energy levels around the nucleus. The outermost or valence electrons of an atom are the ones that take part in chemical reactions. An element’s chemical […]
How does the muscular system work with the respiratory system?
How does the muscular system work with the respiratory system? Respiratory System and the Muscles of Inhalation and Exhalation. The muscular and nervous systems enable the involuntary breathing mechanism. The main muscles in inhalation and exhalation are the diaphragm and the intercostals (shown in blue), as well as other muscles. Are the lungs part of […]
How are the SI units defined?
How are the SI units defined? The SI base units are the standard units of measurement defined by the International System of Units (SI) for the seven base quantities of what is now known as the International System of Quantities: they are notably a basic set from which all other SI units can be derived. […]
What transports osmosis?
What transports osmosis? Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water. Is Osmosis a active process? […]
What is an example of a scalar and a vector?
What is an example of a scalar and a vector? A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge….Difference Between Scalar and Vector. Vector Scalar Example Velocity and Acceleration Mass and Temperature What is a scalar operation? When you add, subtract, multiply or divide a […]
Can a car spring kill you?
Can a car spring kill you? Compressing springs is a very dangerous job. The energy that compressed springs pack is tremendous. If your redneck, home-made coil spring compressor were to fail it could literally crack your skull, take your face off and even kill you. Can coil springs be adjusted? Most import passenger vehicles use […]
What do you mean by fringes of equal width?
What do you mean by fringes of equal width? The occurrence of fringes of equal thickness is due to interference of light reflected from the front and rear boundaries of the film (fringes of equal thickness in reflected light) or of light transmitted directly through the film and light twice reflected at its boundaries (fringes […]
