Without a specific image or description of the diatoms in question, it is difficult to determine if they are "diatoms 2." Diatoms are a type of algae that are characterized by their unique cell walls made of silica. To accurately identify diatoms, it is important to examine their physical characteristics under a microscope, such as their shape, size, and structure. Additionally, diatoms can be further classified into different species, so it is important to have detailed information about the specific diatoms in question in order to accurately identify them. **

Diatoms are microscopic algae that play a crucial role in the marine food web and carbon cycle. However, excessive growth of diatoms, known as a bloom, can lead to harmful algal blooms (HABs). These blooms can deplete oxygen in the water, leading to fish kills and other negative impacts on marine life. Additionally, some species of diatoms produce toxins that can harm marine animals and humans. Therefore, the problem with diatoms lies in their potential to cause harmful algal blooms and produce toxins that can negatively impact marine ecosystems and human health. **

Tetra Algumin is primarily designed to combat green water algae in aquariums, not diatoms. Diatoms are a type of brown algae that are best treated by addressing the underlying causes such as excess nutrients and inadequate water circulation. While Tetra Algumin may have some impact on diatoms due to its ability to reduce organic nutrients, it is not specifically formulated to target diatoms. It is important to address the root causes of diatom growth in order to effectively control and prevent their recurrence. **

Diatoms are a type of algae that play a crucial role in the carbon cycle by absorbing carbon dioxide and producing oxygen through photosynthesis. In 1902, the Nobel Prize in Chemistry was awarded to the German scientist Eduard Buchner for his work on fermentation, which involved studying the enzymes involved in the process. Enzymes are essential for various biological processes, including those in diatoms that enable them to photosynthesize and contribute to the global carbon cycle. Thus, diatoms indirectly relate to the Nobel Prize through the study of enzymes and their role in biological processes. **

The amount of insulation required for a facade renovation depends on various factors such as the climate, building codes, and the existing condition of the building. In general, the insulation should be sufficient to meet the energy efficiency requirements of the building and to improve its thermal performance. It is important to consult with a professional architect or engineer to determine the specific insulation needs for a facade renovation project. **

The roofing underlayment serves as a secondary layer of protection against water infiltration and helps to prevent leaks in the roof. It also provides an additional barrier against wind-driven rain and snow. In terms of insulation, the underlayment can help to improve the overall energy efficiency of the roof by reducing heat loss and preventing drafts. Additionally, it can provide a smooth surface for the installation of the final roofing material, such as shingles or tiles. **

When renovating a roof for thermal insulation, it is recommended to consider adding insulation materials such as fiberglass, cellulose, or foam board. These materials can help reduce heat loss and improve energy efficiency. Additionally, sealing any gaps or cracks in the roof structure can prevent air leakage and further improve insulation. Lastly, installing a reflective roof coating can help reduce heat absorption and keep the interior of the building cooler. **

Gutters are typically available in standard sizes of 5 inches and 6 inches. The 5-inch gutters are commonly used for residential properties, while the 6-inch gutters are often used for commercial buildings or homes with larger roofs. It is important to choose the appropriate size of gutters based on the size of the roof and the amount of rainfall in the area to ensure proper drainage and prevent water damage. **
