If \( r \) and \( r' \) denote the angles inside the prism having angle of prism \( 50^\circ \), considering that during the interval of time from \( t = 0 \) to \( t = T \), \( r \) varies with time as \( r = 10^\circ + t^2 \). During this time \( r' \) will vary with time as
The variations of resistivity \( \rho \) with absolute temperature \( T \) for three different materials X, Y, and Z are shown in the graph below. Identify the materials X, Y, and Z.
The graph between variation of resistance of a wire as a function of its diameter keeping other parameters like length and temperature constant is
Which of the following graphs represent the variation of magnetic field \( B \) with perpendicular distance \( r \) from an infinitely long, straight conductor carrying current?
The anode voltage of a photocell is kept fixed. The frequency of the light falling on the cathode is gradually increased. Then the correct graph which shows the variation of photo current \( I \) with the frequency \( f \) of incident light is
The term reproduction is a biological process that means to reproduce. It is a process by which an organism reproduces an offspring that is biologically similar or identical to its parents. Reproduction accredits and ensures the continuity of species, generation after generation, and is the main character of life on earth.
There are two types of reproduction such as:
It is the production an offspring by a single parent beyond the formation and fusion of gametes. The young one obtains all its genes from one parent, so are identical.
Sexual reproduction is mostly biparental, includes the formation of meiosis gamete usually fertilization also, instigates genetic variation in the offspring, and plays a role in the evolution of species, found in higher plants and animals.
