9486068416 EXPLANATION Answer can be obtained easily from elemination - Eliminate A ( Calopyllum) because it is Dicot. Sorgum and Cocos (coconut) is parallel as we seen day to day. The remaining is Smilax Actually it is free central plancentation Sementides are the information-carrying molecules such as proteins, DNA, and RNA. Based on sequential transfer of genetic information DNA is a primary sementide, RNA a secondary sementide, and proteins are tertiary sementides
Mainly from Rhizome and roots of the plants but in some cases it can from stem also
H1 is called as Linker molecule.The core is consist of H2A, H2B,H3 and H4
In Cycas - 3-celled pollen are shed from the pollen sacs and pollinated by wind.

Neoendemic species have recently arisen, through divergence and reproductive isolation or through hybridization and polyploidy in plants Paleoendemism-refers to species that were formerly widespread but are now restricted to a smaller area Allopatric - Different Geographic area (Allo- Different) / Sympatric - Same Geographic area (Sym -Same)

EXPLANATION Fibroin is an insoluble protein present in silk created by spiders, the larvae of Bombyx mori, other moth genera such as Antheraea, Cricula, Samia and Gonometa, and numerous other insects /Alpha Keratin is found in hair, wool, horn, and tails./ Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched /Collagen is the most abundant protein in our bodies, especially type 1 collagen. It's found in muscles, bones, skin, blood vessels, digestive system and tendons Ribozymes (ribonucleic acid enzymes) are RNA molecules that are capable of catalyzing specific biochemical reactions, similar to the action of protein enzymes / Isozymes enzymes that differ in amino acid sequence but catalyze the same chemical reaction. Interferons (IFNs) are low molecular weight proteins that belong to the class of glycoproteins known as cytokines. IFNs are part of the non-specific immune system and are an important first line of defense against viral infections WARNING - THIS ANSWER MAY VARY FROM AUTHOR TO AUTHOR (BUT MOST OF THEM AGREED 6-8) - SEE THE FAMOUS PAPER The controversy over the minimum quantum requirement for oxygen evolution (Jane F Hill AND Govindjee) Glyoxysomes are specialized peroxisomes found in plants (particularly in the fat storage tissues of germinating seeds) and also in filamentous fungithat initiate the breakdown of fatty acids and additionally possess the enzymes to produce intermediate products for the synthesis of sugars by gluconeogenesis.
