Reproduction and Life History
There are three morphologically distinct stages in the life cycle; the egg “finally” develops into larva which is converted into motionless pupa that finally develops into an adult. It some primitive insects the metamorphosis is incomplete.
Real and Apparent Weight (F.Sc – Physics – Chapter 5.11)
We often hear that objects appear to be weightless in a spaceship circling round the Earth. In order to examine the effect in some detail, let us first define, what do we mean by the weight? The real weight of an object is the gravitational pull of the Earth on the object.
Phylum: Arthropoda – Animals with Jointed Legs
The body is segmented. Each segment is attached to its neighbor by means of a modified portion of cuticle which is thin and flexible, they possess jointed appendages. These appendages have been modified for specialized functions.
Artificial Satellites (F.Sc – Physics – Chapter 5.10)
If, however, a satellite in a circular orbit is at an appreciable distance h above the Earth’s surface, we must take into account the experimental fact that the gravitational acceleration decreases inversely as the square of the distance from the centre of the Earth (Fig. 5.16).
Grade Bilateria Flatworms Part 3 (F.Sc – Biology – chapter 10)
The body is metamerically segmented. The body becomes divided transversely into a number of similar parts or segments. The subdivisions may be indicated externally by constrictions of the body surface.
Grade Bilateria Flatworms Part 2 (F.Sc – Biology – chapter 10)
The name nematode means “pointed ends”. The animals included in this group have elongated worm like body with pointed ends. The nematodes are triploblastic and pseudocoelomates. One end of the body is anterior, however the head is not clearly marked and there are no special sense organs at this end
Rotational Kinetic Energy (F.Sc – Physcis -5.9)
If a body is spinning about an axis with constant angular velocity ώ, each point of the body is moving in a circular path and, therefore, has some K.E. to determine the total K.E. of a spinning body,
The Concept of Evolution
Genetic drift, mutation and gene flow are the secondary mechanisms. Evolution takes place in the consequence of transforming in genetic characters. There are some popular characteristics in human being e.g. eye color and hair color. Evolution is applied is now a day in Biology and its branches.
Solid State Devices
A semiconductor is a material that produces electrical transference between conductor and insulator. Semiconductor mostly deal with electron and in other, it deals with electron holes. Both are called charge carrier. Some are very good conductor, e.g.
Leisure (Poem)
One has no time to enjoy and look at the wonders around us. He has mentioned. The animals on the pastures, the stars in the sky, the music and smiles around him. According to the poet’s point of view, a man’s life is so full of worries and care that he cannot even stand and look up at things as they are around him.
