What is the order of meiosis 1 and 2? Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell. What are the steps of mitosis? Today, mitosis is understood to involve five phases, based on the physical state […]

What is energy food value? The energy value of a food indicates its value to the body as a fuel. This may be less than the heat value obtained experimentally by ‘burning’ the food outside the body in what is called a ‘bomb calorimeter’. After a food is ingested, some of its energy may be […]

What is a wave pattern? : an undulating line used ornamentally (as in the decoration of pottery) What are the different wave patterns? There are three categories: Longitudinal wave *s – Movement of the particles are parallel to the motion of the energy. Sound waves moving through the air is an example of this type […]

What is the difference between motion in 1d and 2d? The motion of a body in a straight line is called one-dimensional motion. The motion of a body in a plane is called two-dimensional motion. The motion of a body in a space is called three-dimensional motion. When only one coordinate of the body changes […]

What is the period for Y Sinx? 2π What does 2 pi n mean? 2nπ comes from the fact that 2π is the period of the cosine function. What is 2 pi used for? When a circle’s diameter is 1, its circumference is π. When a circle’s radius is 1—called a unit circle—its circumference is […]

Will water turn into ice at room temperature? Researchers in Korea have shown that liquid water can freeze into ice at room temperature under certain conditions. Heon Kang and co-workers at Seoul National University confined water in a nano-sized gap and showed that it froze when an electric field was applied (Phys. Rev. Lett. How […]

What is good health class 9? Health is a state of complete physical, mental and social well being. For a healthy life cycle,person needs to have a balanced diet,has to take exercise,lives in proper shelter,takes enough sleep,have good hygiene. Good economic condition and jobs are therefore needed for individual health. Why do we fall sick? […]

What is energy and its formula? For the potential energy the formula is. P.E. = mgh. Unit. The SI unit of energy is joules (J), which is named in honour of James Prescott Joule. What is G in potential energy formula? The formula for potential energy depends on the force acting on the two objects. […]

Why do electrons get transferred? Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. It occurs without direct contact between the two objects. What is the purpose of transferring […]

What are the 3 properties of radiation? What are the Three Types of Radiation? When atoms decay, they emit three types of radiation, alpha, beta and gamma. The alpha and beta radiation consist of actual matter that shoots off the atom, while gamma rays are electromagnetic waves. What kind of electromagnetic radiation can be detected […]
