The research aims to determine the effectiveness of discovery learning models assisted by puzzle mind maps on the activities and learning outcomes of the Structure and Function of Animal Tissue Materials. This research was conducted at SMAN 13 Semarang in the Odd Semester Academic Year 2018/2019. This research is a Quasi Experiment study with Nonequivalent Control Group Design. The population in this research were all students of Class XI MIPA of SMAN 13 Semarang. The sample used was Class XI MIPA 1 and XI MIPA 2 which was taken by purposive sampling technique. The results showed that the learning outcomes showed that there were no significant differences between the learning outcomes of the control class and the experimental class (sig. ˃ 0.05). Data on student activity obtained by observation and filling in questionnaire sheets showed that 100% of the experimental class students entered very active and active category, while in the control class showed that 89.3% of students entered were very active and active category. This shows that the experimental class is able to surpass the indicator ≥ 90% in the student activity. The conclusion is the application of discovery learning models assisted by puzzle mind map of the Structure and Function of Animal Tissue Materials effectively applied to increase student activity but not to improve learning outcomes.

Education is one of the supporting factors to improve the quality of human resources and is shown by the higher standard of education and along with progress in the 21st century. In this century, we know the term generation millennial, in general, it is found among students who are approaching adulthood and already have many communication devices inform of the smartphone. The use of a smartphone as educational media that is not maximally used.-based electronic teaching materials for android students is not available until now although there are currently very few to use. The purpose of this study is to produce an e-book based on android the structure and function of animal tissue that is valid and practical. This type of research is research and development. The method used in this research development is to use a plomp model. The object of the study consisted of one biology teacher and 35 students of Class XI MIPA at SMAN 3 Padang. Based on the results of this study produced e-book based on android on the material structure and function of animal tissue that showed an average value of 86.56% (very valid) based on validator ratings, practicality assessments by biology teachers showed an average value of 96.25% (very practical) and practicality assessment of field tests by 35 students obtained an average value of 86.66% (very practical). So, it can be concluded that the e-book based on android on the material structure and functions of animal tissue developed is very valid and very practical to use.

The synaptic connections in cat retina that link photoreceptors to ganglion cells have been analyzed quantitatively. Our approach has been to prepare serial, ultrathin sections and photograph en montage at low magnification (˜2000X) in the electron microscope. Six series, 100-300 sections long, have been prepared over the last decade. They derive from different cats but always from the same region of retina, about one degree from the center of the visual axis. The material has been analyzed by reconstructing adjacent neurons in each array and then identifying systematically the synaptic connections between arrays. Most reconstructions were done manually by tracing the outlines of processes in successive sections onto acetate sheets aligned on a cartoonist's jig. The tracings were then digitized, stacked by computer, and printed with the hidden lines removed. The results have provided rather than the usual one-dimensional account of pathways, a three-dimensional account of circuits. From this has emerged insight into the functional architecture.

With increase use of tissue-integrated prostheses in recent years it is a goal to understand what is happening at the interface between haversion bone and bulk metal. This study uses electron microscopy (EM) techniques to establish parameters for osseointegration (structure and function between bone and nonload-carrying implants) in an animal model. In the past the interface has been evaluated extensively with light microscopy methods. Today researchers are using the EM for ultrastructural studies of the bone tissue and implant responses to an in vivo environment. Under general anesthesia nine adult mongrel dogs received three Brånemark (Nobelpharma) 3.75 × 7 mm titanium implants surgical placed in their left zygomatic arch. After a one year healing period the animals were injected with a routine bone marker (oxytetracycline), euthanized and perfused via aortic cannulation with 3% glutaraldehyde in 0.1M cacodylate buffer pH 7.2. Implants were retrieved en bloc, harvest radiographs made (Fig. 1), and routinely embedded in plastic. Tissue and implants were cut into 300 micron thick wafers, longitudinally to the implant with an Isomet saw and diamond wafering blade [Beuhler] until the center of the implant was reached.

By conventional electron microscopy, the formed elements of the nuclear interior include the nucleolus, chromatin, interchromatin granules, perichromatin granules, perichromatin fibrils, and various types of nuclear bodies (Figs. 1a-c). Of these structures, all have been reasonably well characterized structurally and functionally except for nuclear bodies. The most common types of nuclear bodies are simple nuclear bodies and coiled bodies (Figs. 1a,c). Since nuclear bodies are small in size (0.2-1.0 μm in diameter) and infrequent in number, they are often overlooked or simply not observed in any random thin section. The rat liver hepatocyte in Fig. 1b is a case in point. Historically, nuclear bodies are more prominent in hyperactive cells, they often occur in proximity to nucleoli (Fig. 1c), and sometimes they are observed to “bud off” from the nucleolar surface.

Correlations between structure and function of biological macromolecules have been studied intensively for many years, mostly by indirect methods. High resolution electron microscopy is a unique tool which can provide such information directly by comparing the conformation of biopolymers in their biologically active and inactive state. We have correlated the structure and function of ribosomes, ribonucleoprotein particles which are the site of protein biosynthesis. 70S E. coli ribosomes, used in this experiment, are composed of two subunits - large (50S) and small (30S). The large subunit consists of 34 proteins and two different ribonucleic acid molecules. The small subunit contains 21 proteins and one RNA molecule. All proteins (with the exception of L7 and L12) are present in one copy per ribosome.This study deals with the changes in the fine structure of E. coli ribosomes depleted of proteins L7 and L12. These proteins are unique in many aspects.

The epithelium plays a critical role in the maintenance of laryngeal health. This is evident in that laryngeal disease may result when the integrity of the epithelium is compromised by insults such as laryngopharyngeal reflux. In this article, we will review the structure and function of the laryngeal epithelium and summarize the impact of laryngopharyngeal reflux on the epithelium. Research investigating the ramifications of reflux on the epithelium has improved our understanding of laryngeal disease associated with laryngopharyngeal reflux. It further highlights the need for continued research on the laryngeal epithelium in health and disease.
