Abstract

This research aims to identify the reproduction and development of Bryophyta, especially the moss Octoblepharum albidum. Moss is a group of lower plants that play an important role in ecosystems, especially in humid areas such as tropical rainforests. The method used in this research includes observing the morphology and reproduction of moss using a stereo microscope to observe sporangium and spores. The results showed that Octoblepharum albidum has a lance-shaped leaf morphology, pale green in color, and has a thick texture. There are four brown sporangium, each containing more than 200 spores. This research reveals the importance of Bryophyta in maintaining ecosystem balance and as environmental indicators, as well as providing insight into the factors that influence the growth and development of moss in different habitats.

Abstract

Evolution is characterized by changes over time with one or more inherited traits that we often find in populations of organisms. Fossils themselves can be said to be traces/remains/marks of a life of an organism (animal/plant) that can be directly or indirectly preserved with the earth's crust, naturally occurring and usually solid/hard with a geological age of more than 11,000 years. Horse evolution is one of the interesting adaptations, with morphological changes related to environmental changes. The purpose of this study was to determine the evolution of horses from the fossils found and, to find out how to adapt and the changes that occur from the environment and factors of natural selection. The method used in this study is a literature review from several reference sources. Horse evolution shows how species can adapt to the environment through significant morphological changes, such as a reduction in the number of fingers and an increase in body size. and the role of natural selection in forming physical characteristics that support survival.

Abstract

Equitable vaccine distribution is a global issue that has received increasing attention, especially since the increasing need for vaccines in the face of modern pandemics. This study aims to analyze the inequality in vaccine distribution and the factors influencing vaccine hesitancy through a descriptive qualitative approach, utilizing literature studies and supporting data in the form of graphs. The analysis results show that high-income countries have significantly greater access to vaccines than middle- and low-income countries, creating inequalities that impact public health protection. Furthermore, levels of vaccine hesitancy were found to vary across social groups, with adolescents being the group with the highest rate of rejection due to the influence of misinformation and low trust in health institutions. These findings confirm that the success of a vaccination program is determined not only by the availability of equitable distribution but also by public acceptance, which is influenced by social, psychological, and ethical factors. Overall, this study emphasizes the importance of applying bioethical principles such as justice, beneficence, and autonomy in formulating effective and inclusive vaccination policies.
