re in the universe, there are MANY stars. Some of them are very BIG while others are either medium-sized or small. Our Sun, for INSTANCE is a medium-sized star. EXTREMELY big stars like Betelgeuse are way more BIGGER. When stars like these explode, we call it a supernova.Hope, it helps.

A GAMETE may carry either the dominant or the recessive factor but not both as we FIND in individuals. This is why it is called either as 'principle of SEGREGATION' or as 'law of purity of GAMETES.

ance of OXYGEN and CARBONDIOXIDE is maintained in the atmosphere by the oxygen released by PLANTS during PHOTOSYNTHESIS and carbondioxide released by human,animals ETC. in the atmosphere. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis.

cope is an optical instrument that uses a SYSTEM of PRISMS, lenses or mirrors to REFLECT images through a tube. Light from a distant object strikes the TOP MIRROR and is then reflected at an angle of 90 degrees down the periscope tube.

oid robot is a robot with its body shape BUILT to resemble the human body. The design may be for FUNCTIONAL PURPOSES, such as interacting with human tools and environments, for experimental purposes, such as the study of bipedal locomotion, or for other purposes.A humanoid robot is a robot with its body shape built to resemble the human body. The design may be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of bipedal locomotion, or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the WAIST up. Some humanoid robots also have heads designed to replicate human facial features such as eyes and mouths. ANDROIDS are humanoid robots built to aesthetically resemble humans.

akes are usually caused when rock underground suddenly BREAKS ALONG a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two PLATES are RUBBING against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs.

l Compounds The whole‐number ratios of combining masses in chemical reactions can be readily explained knowing that the BASIC unit of all elements is the atom, which originally meant an indivisible particle. Therefore, one atom of carbon can REACT with either one atom of oxygen, or two ATOMS of oxygen,  equation but not with, say, equation oxygen atoms. The reactions of carbon with oxygen are shown using chemical equations with reactants on the left and products on the right of the arrow. A substance containing atoms of more than one element in a definite ratio is called a compound. The composition of a compound is shown in its chemical formula. In the chemical reaction of carbon and oxygen to form carbon dioxide, the elements are in a definite 1:2 ratio—one atom of carbon with two atoms of oxygen forming the compound carbon dioxide. When SEVERAL atoms are so tightly bonded together that they physically behave as a unit, the unit is called a molecule. (See Figure 1.) Elements and compounds can be molecular. In the carbon dioxide reaction, the O 2 molecule contains 2 atoms of oxygen, and the CO 2 molecule has 3 atoms—1 carbon and 2 oxygen. Five major compounds are built solely of nitrogen and oxygen, as shown in Table 1. Of the five oxides of nitrogen, nitrous oxide is richest in nitrogen, and dinitrogen PENTOXIDE is richest in oxygen.
