Amount of carbon dioxide
Explanation:
The dependent variable in this experiment is the amount of carbon dioxide CO₂ produced by yeast during the experiment.
- The independent variable is the cause in an experiment. It is the variable that causes the change we are measuring. In this experiment, the yeast is the independent variable. The yeast is producing the carbon dioxide.
- The dependent variable is the effect in the experiment. It the variable changing in an experiment.
- The amount of carbon dioxide production is the dependent variable in this experiment.

Answer:
Evolution.
Explanation:
It might have acquired the ability to cause disease due to evolution. Due to evolution, the harmless bacteria can turn into infectious pathogens that cause diseases. Evolution is the change in the characteristics of a species over several generations due to the process of natural selection. This evolution in the bacteria occurs due to changing of environmental conditions which changes the genetic makeup of that harmless bacteria and turn into infectious pathogen.
Answer: Anaerobic, Aerobic
Explanation: Aerobic means with Oxygen,while Anaerobic means without oxygen. Aerobic exercise like running,bike ride,walking increases blood flow. In Aerobic exercise with oxygen,your body produces the muscle need to perform a needed exercise. While in Anaerobic exercise without oxygen means oxygen demand is greater than oxygen supply.
Answer:
To discharge energy gradually in a step-by-step process.
Explanation:
The process of cellular respiration comprises various reactions in which electrons are transferred or mediated from one molecule to another. The reactions taking part in electron transfers are called redox reactions or oxidation-reduction reactions.
With the movement of electrons the energy is released that can be captivated and is used to do work. In cellular respiration, the electrons from glucose move slowly via the electron transport chain ultimately towards oxygen that is, transferring towards lower and lower energy states and discharging energy at each stage.
Cell division is characterized by two important processes called the karyokinesis followed by the cytokinesis. Karyokinesis refers to the division of the nucleus which is followed by the division of the cytoplasm called the cytokinesis. In animal cells, it is by the formation of a cleavage furrow and in plant cells it is by the formation of a cell plate. Cytokinesis results in the formation of two daughter cells. If the cells are treated with chemicals that block cytokinesis, the seperation of cells is not possible leading to the formation of abnormally large sized cells, each containing two nuclei or sometimes can be multinucleated.
