INTRODUCTION Cell isolation and culture are essential tools for the life sciences today specifically in the study of cell function. Isolated cells grown under controlled conditions can be manipulated and imaged at a level of resolution under the microscope‚ that is not possible in whole animals or even tissue explants (Zhang and Kuhn‚ 2011). In its simplest form‚ cell culture involves the dispersal of cells in an artificial environment composed of nutrient solutions‚ a suitable surface to support

Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta

INTRODUCTION Otters belonging to the order Carnivora of class Mammalia‚ are semi-aquatic members of the family Mustelidae which also includes weasels‚ martens‚ polecats‚ badgers‚ skunks‚ grisons and minks. Otters are placed in the sub-family Lutrinae (Khan W. A. et al.‚2010). Genus Lutrogale ;Smooth-coated otter (Lutrogale perspicillata) (Ogamba E.N. & Abowei J.F.N.‚2012) ( Figure 1) .The smooth otter is the largest otter in Southeast Asia that comment otter. It was named for its shorter‚ smoother

Significance of Planarians Planarians are non-parasitic flatworms of the phylum Platyhelmintes found in fresh water like ponds or lakes. In my research paper I focused on Schmidtea mediterranea planarians found in Tusinia and southern Europe which are extensively used as a model organism to study development and regeneration process (Newmark 2012). Schmidtea mediterranea are chosen by researcher in molecular biology and genetics field because these planarians have diploid chromosomes and are hermaphrodite

balls on earth‚ the roly- poly. They are commonly known as the roly-poly‚ also pill bug‚ and wood lice. Its scientific name is Armadilidum vulgare. It is actually not an insect‚ it is an isopod ( a type of arthropod). It’s genus is Armadilidum‚ it’s Phylum is Arthopoda‚ and Subphylum is Crustacea. I have observed that the exoskeleton is a blue-gray‚ it is an invertebrate‚ it’s mouth‚ antennae and eyes are located on it’s head‚ and it rolls into a perfect sphere as defense when being disturbed or threatened

Zoology Connect Quizzes Chapter1 Your friend releases a pair of goldfish from an aquarium into a pond. The fish survive long enough to produce many young. Returning to the pond after several years‚ you find that only drab olive-brown offspring remain from the original brightly colored golden parents. Select any factors listed below that would have promoted the survival of olive-brown fish over the brightly colored variety. The fish in the wild spent most of their energy finding food and
