Answer:

The independent variable is the amount of glucose being supplied and the dependent variable is the amount of alcohol being produced.

An independent variable can be described as the variable which is being changes in a scientific experiment so that its effects can be studies.

The dependent variable can be described as the variable which is under study and which gets affected by the changes in the independent variable.

The control that can be designed for this experiment can be another experiment in which the amount of glucose is kept constant in each of the yeasts.

Classify the steps involved in the formation of a solution as being endothermic or exothermic. separation of solute molecules se
Alexxx [7]

Answer:

<em>Endothermic reactions:  separation of solute molecules , separation of solvent molecules</em>

<em>Exothermic: formation of solute-solvent interactions</em>

Explanation:

An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.

An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.

Which of the following properties does NOT play a role in trees growing to towering heights by moving water from roots to leaves
jarptica [38.1K]

Answer:

The correct option is;

Water absorbing energy in large amounts to increase energy by a degree of temperature

Explanation:

The growth of trees to towering heights has to do with the formation of plant cell walls which are built by the aggregation Glucose molecules to form Cellulose molecules. The cellulose molecules further combines to form microfibrils by forming hydrogen bonding. The microfibrils that combine to make cell walls

Therefore, the growth of a tree is dependent on the formation of hydrogen bonds between water molecules to enable uptake of water into the plants which enable photosynthetic reaction that result in the formation of glucose

The transpiration, which is the conversion of water into vapor or gas at the leaves facilitates the uptake of more water for the formation of more glucose molecules and creation of hydrogen bonds

The hydrogen bonds between chlorophyll molecules is facilitated by forming hydrogen bond with water molecules.

What is cell surface to volume ratio and why is it important in cell functioning? Can it explain why cells are so small?
MrMuchimi
<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>
