Osmosis and diffusion are both examples of passive transport, neither of which requires energy to cross the cell membrane from areas of high concentration to areas of low concentration. Active transport is the process of moving molecules and ions from areas of low concentration to areas of high concentration. Active transport requires energy in the form of ATP.
Which cell? Animal, or plant?
Euthrophication is caused by excess nutrient run off, such as nitrogen or phosphorus. A common chemical that generally cause euthrophication is fertilizers from farm, if there's heavy rainfall or floods, they're easily washed into the rivers and lakes to cause euthrophication.
Euthrophication generally cause a sudden large scale algao bloom, or other plants, and they may cover the whole surface of water. Once these plants die, decomposers such as bacteria decompose them and take in oxygen for respiration, such that animals from the river originally may die due to lack of oxygen.
Answer:
Type of milk
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. It is the variable that causes the dependent variable to change.
In this experiment, the hypothesis, which shows the relationship between the independent and dependent variable is stated as follows: IF the amount of protein is calculated in three different lipid levels of milk, THEN whole milk will have the highest level of protein. This shows that the amount of protein is dependent on the TYPE OF MILK used, which is the independent variable.
