What are the answers to the following questions on decalcification?

Hey Lucia, good to see you again. Here are the answers to your questions: 1. Decalcification is necessary for: Decalcification is the process of removing calcium salts from tissues, which is essential for preparing hard tissues like bone and teeth for microscopic examination (histology). The correct option is B. B. Bone and teeth histology 2. A chelating agent commonly used for decalcification is: Chelating agents work by binding to calcium ions, slowly removing them from the tissue. EDTA (Ethylenediaminetetraacetic acid) is a widely used chelating agent for decalcification, especially when cellular detail needs to be preserved. The correct option is B. B. EDTA 3. Indicators of decalcification include: To determine if decalcification is complete, several methods are employed. These include checking the tissue hardness (it becomes softer), performing a needle penetration test (the needle should pass through easily), and using radiography (X-rays) to confirm the absence of residual calcium. The correct option is D. D. All of the above Send me the next one 📸
