The animal fauna hypotheticus has a diploid chromosome number of 28. it has a nuclear genome consisting of 2 x 109 bp of b-dna with a g+c content of 60%. a. determine the number of chromosomes and dna molecules in a cell: (i) during g1 of interphase; (ii) at the start of prophase of mitosis; (iii) at the end of anaphase of mitosis; (iv) after cytokinesis of mitosis; (v) at the start of prophase i of meiosis; (vi) at the start of prophase ii of meiosis; and (vii) after cytokinesis of meiosis ii.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
