Answer:Oxygen
Explanation: During cellular respiration, glucose is broken down in the presence of oxygen to form carbon dioxide, water and energy. Glucose + oxygen --> carbon dioxide + water + energy.
The balanced chemical equation for cellular respiration is C6H12O2 + 6O2 --> 6CO2+ 6H2O + Energy

Southern blot helps to get the sequence of DNA that is complimentary to the DNA or RNA probe used
Answer:
Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!
Answer:
4. Variations that help with survival will be passed on to future generations and will rapidly change the whole population.
Explanation:
Variations that help with survival MAY be passed on to future generations, depending on how much pressure that variation relieves. Change may not be rapid, depending on how fecund the species is. Also, it will not change the whole population, only future offspring. The current offspring won't all have the new variation.
Answer:
Lower esophageal sphincter
Explanation:
The biological valves are the muscular structures composed of the smooth muscles which form thick tubular structure to allow the controlled movement of any material through it. The valves in the digestive system are known as the sphincters.
The sphincters control the unidirectional movement of the eaten food, chyme and the bolus in the digestive tract.
A sphincter is present at the lower portion of the oesophagus (food pipe) which contracts to prevent the backflow of the food from the stomach and since the sphincter is present at the lower side of the oesophagus, therefore, is known as the lower esophagal sphincter.
Thus, Lower esophageal sphincter is correct.
