Transportation..

Summary - In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to transport..

A group of people were surveyed to know which mode of transportation they would use to reach their workplace. The results are recorded in the table. Find the experimental probability of a person reaching his/her workplace by bus. Modes of transportation Number of peopl..

. Natural resource and human society are inseparable. Examples: Water and air Most artificial resources created by man draw support directly and indirectly from one or more natural resources. With this, human society is developing with man - made resources on one hand and natural resources on the o..

Growth Regulators - The growth of plants is regulated by certain chemical substances, which are synthesized by the plant in very small quantities. These substances are formed in one tissue or organ of the plant and are then transported to other sites where they produce specific effects on..

Photophosphorylation (Cyclic and Non-cyclic) - Photosynthetic phosphorylation or photophosphorylation is the process of phosphate group transfer into ADP to synthesize energy rich ATP molecule making use of light as external energy source. According to chemi osmotic hypothesis (Mitchell 1..

. The major problem of corrosion occurs with iron (or steel) as it is used as a structural material in industries like construction, infrastructure, bridges, rail transport power transmission, shipbuilding, automobiles, heavy industries etc. Aluminium, another useful structural metal, als..

. The amino acid methionine is transferred from its tRNA onto the newly arrived proline tRNA complex where the two amino acids join by a peptide bond. The process is catalyzed by the enzyme peptidyl transferase located on the ribosome. In this process, the linkage between the first amino acid and i..

. Beyond this, what will be the state of transport sector? If extraction of petroleum is considered as misuse of natural resource then what effective practical alternative is available to replace petroleum? (Note that LPG gas also has restricted source) The manner in which mineral sources..

>Peptiglycons are found in the cell walls of prokaryotic cells. Proteins are polymers of aminoacids arranged in a specific sequence which is decided by the genetic code present in the DNA molecule. The polypeptide chain in a protein may be straight (primary structure) or may form helical coils (sec..
