First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst. hope this helps :)
Answer:
You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.
This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.
Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.

Differentiation in plants refers to the processes by which distinct cell types arise from precursor cells and become different from each other. Plants have about a dozen basic cell types that are required for everyday functioning and survival. Additional cell types are required for sexual reproduction. While the basic diversity of plant cell types is low compared to animals, these cells are strikingly different. For example, some cells such as parenchyma cells retain the potential to respond to environmental and/or hormonal signals throughout their life and, under the right conditions, can be transformed into another cell type (transdifferentiation). Other cells such as the water-conducting vessel elements undergo cell death as part of their differentiation pathway and thus can never transdifferentiate to another cell type

According to NIDA, THC causes brain cells to release dopamine, which results in bliss. It also affects how the hippocampus, a region of the brain involved in creating new memories, processes information. THC has the ability to alter perception, reasoning, and cause delusions.
<h3>What is cannabis ?</h3>
Cannabis sativa or Cannabis indica plant parts such as dried leaves, flowers, stems, and seeds are referred to as marijuana. The plant contains the psychoactive compound THC as well as several other related compounds. Extracts from the cannabis plant can also be produced.
- Marijuana's chemical components have hallucinogenic effects on both the body and the mind. It might be addictive and harmful to some people's health.
- THC, the main psychoactive ingredient, energises the region of the brain that reacts to pleasure, such as food and sex. Dopamine is released as a result, making you feel euphoric and at ease
