What can they give for biology group 4 for practical they have already given fish and chick for disection for the first 3 days

Given that fish and chick dissections have already been covered, Group 4 for biology practicals might be given other common experiments. Here are some possibilities:

• Microscopy and Cell Observation: Preparing and observing slides of plant cells (e.g., onion epidermis, Elodea) or animal cells (e.g., cheek cells) to identify cell structures.
• Plant Physiology Experiments: Investigating osmosis (e.g., using potato strips in different sugar solutions) or factors affecting the rate of photosynthesis (e.g., light intensity on Elodea).
• Enzyme Activity: Studying the effect of factors like temperature or pH on the rate of an enzyme reaction (e.g., amylase breaking down starch).
• Food Tests: Identifying the presence of nutrients like starch, reducing sugars, proteins, and fats in various food samples.
