ImpressionImpressionis an image retained as a consequence of experience; generally the image of an object is retained as an impression.Amental imageormental pictureis the representation in a person's mind of the physical world outside of that personAconceptis a generalization or abstraction from experience or the result of a transformation of existing ideas. It is sort of similar to an image formed in mind.A definitionis making or describing something definite, distinct, or clear as to make a mental image of that thing.
96. Which of the following processes involves chloroplast? chemical energy
Conversion of light energy to chemical energyThe green pigment chlorophyll converts light energy into chemical energy stored in the bonds of the compounds formed in photosynthesis.
97. Besides solid, liquid and gas, what is the fourth form of matter?
PlasmaPlasma, the 4thstate of matter, is superheated gas.The 5thstate of matter is Bose-Einstein Condensates which are supercooled particles.
98. Which of the following is a heterotroph?
GrasshopperHeterotroph is an organism deriving its nutritional requirements from complex organic substances through heterotrophy. In other words, they are organisms that can not make their own food.Heterotrophy(many + nourishment) is the process where existing organic molecules are used by an organism for its energy needs; in maintenance, growth and reproduction
99. Which type of reaction does the general equation (AB+energy->A+B) show? A. Endothermic synthesisB. Exothermic decomposition C. Exothermic synthesisD. Endothermic decomposition
Endothermic decompositionEndothermic reaction means energy is needed for the reaction to proceed. Exothermic reaction releases energy as a product.Decomposition is when a large compound (example, AB) is broken down into simpler ones (example, A and B).
100. Iron is what type of magnetic material?
FerromagneticFerromagnetismis the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.Paramagnetismis a form of magnetism whereby certain materials are attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.Diamagneticmaterials create an induced magnetic field in a direction opposite to an externally applied magnetic field, and are repelled by the applied magnetic field. In contrast, the opposite behavior is exhibited by paramagnetic materials.
