Samira watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. The

ending substances did not look the same as the starting substances. Samira was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. She created a model of the repeating groups of atoms that might make up the two ending substances. Does her model correctly show why the properties of the ending substances are different from the properties of the starting substances? Describe what could be correct or incorrect about her model.

Answer:

<em>Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant.</em>

Explanation:

Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side. But as the diagram shows, Sameera has mistakenly added a new element to one of her products which will be wrong.

What is the difference between mechanical digestion and chemical digestion?
Bad White [126]

Answer:

So, Mechanical and Chemical Digestion is the way of breaking down foods in the body. The difference between Mechanical and Chemical Digestion is, Mechanical Digestion involves the body's movement to make the food smaller and Chemical Digestion involves enzymes to break the food down.

Explanation:

Since Mechanical Digestion involves moving around to break the food down, you would get up and walk around a little to burn it to make it work and Chemical Digestion is just using the natural enzymes in the body to break food down.

ur data for diffusion of water across a differentially permeable membrane in response to a sucrose gradient could be graphed wit
musickatia [10]
The slopes show that sucrose gradient affects change in weight.

The slopes will be different because higher gradient concentration of sucrose will result in the higher amount of water moved. This means the higher sucrose gradient concentration, the more change in weight of the water.
