Answer:
Nucleus
Explanation:
The nucleus stores hereditart material and coordinates activities of the cell
The answer is D. NADH to NAD+
When no oxygen is present, anaerobic respiration occurs.It is the only way to produce ATP in this condition.NAD+ is necessary because it is converted into NADH and at the same time ADP is converted to ATP in the reaction of pyruvate synthesis from glucose.Therefore, NADH must be converted to NAD+ in order to have NAD+ always present in the cell.
The answer is B) Chlorophyll
Answer:
The correct answer is true.
Explanation:
Swallowing of food is the process of passing the food from the mouth to the stomach through the way of the throat (pharynx) and esophagus. This process takes place in three stages: oral, pharyngeal, and esophageal stages
During the pharyngeal stage, epiglottis which is a leaf-shaped flap of cartilage located at top of the larynx (a muscular organ forming voice box) perform functions in response to the swallowed food as the larynx lift up or rises inside the neck to close the epiglottis while the epiglottis moves downward to cover it, providing more airway protection.
Thus, true is the correct answer.
The answer is PRODUCERS.
Plants are producers and perform photosynthesis.
They use the sunlight, that provides them with energy, and take the carbon dioxide from the atmosphere, that helps reducing it.
Photosynthesis is a way for them to make their own food (sugars), necessary for them to stay alive and to produce oxygen. Both will be needed for their cellular respiration, a process that occurs in the mitochondria, and will produce energy, in the form of ATP, and CO2.
The carbon dioxide that they produced in cellular respiration can be used for photosynthesis.
