Excess intake of antibiotics is harmful because too much can change bacteria so much that antibiotics don't work against them. So technically your teaching good bacteria to be bad.
Answer : Broadly solids are divided into three categories;
i) Crystalline solids have a regular definite structure, in which the particles pack in a repeating pattern from one edge of the solid to the other.
ii) Amorphous solids have a random structure, with little unorganized pattern long-range order.
iii) Polycrystalline solids are those where an aggregate which consists of a large number of small crystals or grains in which the structure is regular, but the crystals or grains are found to be arranged in a random fashion.
Also solids can be divided into 3 more categories according to their bonds;
i) Covalent solids, like diamond, which forms crystals that can be viewed as a single giant molecule made up of an almost endless number of covalent bonds.
ii) Ionic solids are basically salts, such as NaCl, in which the molecules are held together by the strong force of attraction between ions of opposite charge.
iii) Metallic solids are found in metals which have the force of attraction between atoms of metals, such as copper and aluminum, or alloys, such as brass and bronze, are metallic bonds.
Answer :
Example of polar covalent molecules H-O-H(water), ammonia
Explanation:
The presence of intermolecular Hydrogen bonding makes the boiling point of water unexpectedly high, and the polar covalent nature makes it dissolve polar solute/compound
All of the above
Explanation:
Science is a methodical way of investigating the world around us in order to find out the truth and facts about them. Technology is the practical aspect of science.
- The knowledge and understanding of x-rays as part of the electromagnetic radiation made it possible to use the rays to study the internal structures of substances.
- The discovery of radioactivity has led to the development of nuclear energy that are produced in nuclear reactors.
- Satellites are built on the principles of science.
- Robotic machines are based on scientific studies and electricity originated from a good knowledge of the atom.
