The habit of people who live in cities and villages likes instant smells, for example, consuming soft drinks. One of the soft drinks popular in the community is carbonated drinks. This study aims to determine the effect of carbonated drinks on blood glucose levels of mice. This study used 21 male mice Balb C strain aged 2-3 months, which was divided into 3 groups, namely K1 given aquadest dose of 0.86 ml / 20 g body weight. K2 is given a carbonated drink dose of 0.43 ml / 20 g body weight. K3 was given a carbonated drink dose of 0.86 ml / 20 g body weight. All treatments were given for 14 days. The average increase in blood glucose levels of mice in KI, K2, and K3 were 16.71 mg / dl, 11.63 mg / dl, and 67.59, respectively (P<0.05). The results of the study showed that there was an increase in blood glucose levels in all treatments. However, the highest increase in blood glucose levels is in K3 (67.59 mg / dl). From the results of the study, it was concluded that carbonated drinks can affect blood glucose levels in mice, but this increase is still within normal limits.

Biology lessons conducted online during the COVID-19 pandemic have hampered school implementation practicum activities. Therefore, it is necessary to conduct research that aims to describe the implementation ofbiology practicum during online learning. This research was conducted to determine the impact of online osmosis practicum during the COVID-19 pandemic in class XI MIPA 4 SMA Negeri 1 Sindang with a sample of 27 students of class XI MIPA 4 and 1 biology teacher. The method used in this research is descriptive qualitative. The sampling technique was carried out by the purposive sampling method. The instruments used are observation sheets, questionnaire sheets, interview sheets, documentation, and field notes. The data analysis technique used is descriptive qualitative analysis. The osmosis practicum process is carried out independently by students using the guidance from the teacher provided. The practicum results are then reported in an activity video, and the teacher will check the video. The results of the research carried out showed that the implementation of the osmosis practicum went well. The readiness of the tools and practicum materials is inthe very good category, students' understanding of doing practicum is in a good category, the conclusions are in a good category, and the practicum report is in the very good category. From the results obtained, it can beconcluded that the implementation of the osmosis practicum in class XI MIPA SMA Negeri 1 Sindang was carried out online is implemented properly and effectively.

Critical thinking ability refers to an individual's capacity for in-depth thought due to the development of diverse thinking talents, including cognitive capabilities, in response to the acquired information. The purpose of the present study was to investigate the relationship between critical thinking skills, biology learning outcomes, and the visual learning style of students. The study used the correlational research method to ascertain the association between critical thinking abilities and biology learning outcomes among students with a visual learning style in class XI MIPA SMAN 6 Tasikmalaya. To this end, 40 students with predominating visual learning styles were selected from 137 students from class XI MIPA 4-7 at SMAN 6 Tasikmalaya. They were asked to fill in a learning style questionnaire with 23 statements. Moreover, they were asked to answer the nine-question evaluation of students' critical thinking abilities regarding biology topics. Students completed learning outcomes from the Year-End Assessment (PAT) grade XI MIPA in biological issues. Pearson product-moment correlation was employed to answer the research question. The result of the study indicated there is critical thinking ability had a limited association with learning outcomes in students who chose a visual learning approach. The correlation coefficient (R) of 0.365 and coefficient of determination (R2) of 0.133 attested to this. The findings revealed that both critical thinking skills and visual learning styles could predict learning outcomes.
