To apply a new waterproofing membrane on top of an old bitumen waterproofing membrane, the surface of the old membrane should be thoroughly cleaned and prepared. Any loose debris, dirt, or old adhesive should be removed to ensure proper adhesion of the new membrane. Once the surface is clean, a primer should be applied to promote adhesion between the old and new membranes. Finally, the new waterproofing membrane can be installed according to the manufacturer's instructions, ensuring that it is properly sealed and bonded to the old membrane to provide effective waterproofing. **

Yes, teachers need evidence to support their instructional decisions and to demonstrate student learning. Evidence can come in the form of student work, assessments, observations, and data analysis. By using evidence, teachers can make informed decisions about their teaching practices, identify areas for improvement, and provide justification for their instructional choices. Additionally, evidence helps teachers to communicate with students, parents, and administrators about the effectiveness of their teaching methods and the progress of their students. **

A utility knife or a sharp blade is typically used to cut the waterproofing membrane. It is important to use a sharp tool to ensure clean and precise cuts, which will help in achieving a proper seal and prevent water leakage. Care should be taken to avoid damaging the underlying surface while cutting the membrane. **

Ideally, the waterproofing membrane should be applied in dry weather to ensure proper adhesion and effectiveness. If the membrane is applied and then it rains before it has fully cured, it can compromise its ability to create a watertight seal. Water exposure during the curing process can lead to delamination, reduced adhesion, and potential leaks. Therefore, it is best to apply the waterproofing membrane when there is no rain in the forecast and allow it to fully cure before any water exposure. **

Cheating typically involves breaking rules or engaging in dishonest behavior to gain an unfair advantage. While evidence may not always be readily available, the act of cheating implies a deliberate intention to deceive or manipulate a situation for personal gain. Therefore, cheating does not necessarily assume evidence, but rather a conscious decision to act in a dishonest manner. **

One evidence of ions is their ability to conduct electricity. Ions are charged particles, either positively or negatively charged, and when they are dissolved in a solution or melted, they can carry an electric current. Another evidence of ions is their behavior in a magnetic field. Positively charged ions will be attracted to the negative pole of a magnet, while negatively charged ions will be attracted to the positive pole. Additionally, ions can participate in chemical reactions where they exchange electrons with other ions or molecules, leading to the formation of new compounds. **

Yes, there is abundant evidence for photosynthesis. Scientists have conducted numerous experiments that demonstrate the process of photosynthesis, including measuring oxygen production, carbon dioxide uptake, and the conversion of light energy into chemical energy. Additionally, the discovery of chlorophyll, the pigment responsible for capturing light energy in plants, further supports the existence of photosynthesis. The overall understanding of how plants and other photosynthetic organisms convert sunlight into energy is well-established and widely accepted in the scientific community. **

Evidence for evolution comes from a variety of sources, including the fossil record, comparative anatomy, embryology, molecular biology, and biogeography. Fossil evidence shows a progression of life forms over time, with more primitive organisms found in lower rock layers and more advanced organisms found in higher layers. Comparative anatomy and embryology reveal similarities in the structures and development of different species, suggesting a common ancestry. Molecular biology provides evidence of shared genetic sequences and biochemical pathways among different species. Biogeography shows patterns of species distribution that are best explained by evolution and continental drift. Together, these lines of evidence provide strong support for the theory of evolution. **
