Has movement my because it moves with any little air going towards it; it moves with the air.
Answer:
Uncontrollable cell division.
Explanation:
Cancer is a disease which is caused when cells division is uncontrollable and spread into surrounding cells and tissues. Mutations in genes is also responsible for the cause of cancer because this mutation accelerate the rate of cell division or inhibiting normal controls on the system, such as programmed cell death. When the mass of cancerous cells grows with the passage of time, it turn into a tumor.
Answer:
The sour flavors come from lactic and acetic acids produced by inevitable environmental bacteria, which are working on the flour's sugars along with the yeast. Different bacteria make different sour flavors

Explanation:
The process of cellular respiration, which generally involves the synthesis of energy from carbohydrate molecule (glucose), occurs in four major steps in eukaryotic cells. These steps are glycolysis, kreb cycle, bridge or intermediate step and oxidative phosphorylation (electron transport chain).
The features of each step is highlighted below:
GLYCOLYSIS: This is the first stage if cellular respiration in which Glucose is broken down into 2 pyruvic acid (pyruvate). It can occur without oxygen in the system and it uses 2 ATP molecules to start the process.
INTERMEDIATE STAGE: This stage is also called bridge or transition reaction. It does not produce any ATP molecule but only prepares the reaction for aerobic respiration in the mitochondria by turning Pyruvate molecule into acetyl CoA.
KREB'S CYCLE: This is the third step in the process. AcetylcoA undergoes series of chemical processes to release 4 carbon dioxide molecules and generates FADH2 and NADH electron carriers. It takes two cycles to process two glucose molecules that is used in the respiration process.
ELECTRON TRANSPORT CHAIN: In this stage, approximately 34 ATP molecules are produced in the mitochondria using enzyme called ATP synthase, which catalyse the conversion of ADP to ATP.
ANAEROBIC RESPIRATION: This type of respiration occurs in the absence of oxygen. In animal cells, lactic acid/lactate is produced and stored in the muscle as an end product
