Class 12 BIOLOGY- Reproduction in Organism

DONLOAD as PDF L ife Span represent the ‘period of time from birth to the natural death’. It very with organism to organism. Life span does not depend upon size and shape of organism.  For example: 1- The size of crow (15 year) and parrot (140 year) are not very different but their life span show a wide difference. 2- A mango tree (100 year) has a much shorter life span as compared to a Banyan tree(200 year). ..................................................................................................................................................

ChemDraw- Full Software

Arya9 Science Group ChemDraw is the drawing tool of choice for chemists to create publication-ready, scientifically intelligent drawings for use in ELNs, databases and publications and for querying chemical databases. A chemical drawing solution that chemists across multiple chemistry disciplines can trust to accurately handle and represent organic, organometallic and polymeric and biopolymer materials (including amino acids, peptides and DNA and RNA sequences) and to deal with advanced forms of stereochemistry. Chemists who use ChemDraw to predict properties are able to save time and reduce costs by identifying compounds that are likely to have the desired properties before actually synthesizing them. Chemists can also save time and increase data accuracy using ChemDraw to generate spectra, construct correct IUPAC names, and calculate reaction stoichiometry. A powerful set of tools to handle substructural query types (such as variable points of attachment, Rgroups, ring/ch
