Answer:
(a).concentrated lactic acid and that of NAD+.
(b).use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
Explanation:
To understand this question and be able to solve this question efficiently we have to understand the concept of "respiration''. But, the short and the most simple answer to the question above can be found in the first statement of the question.
The electron transport chain include the cycle that occurs during glycolysis, fermentation and the transformation of NAD+ to form NADH and vice versa.
In the research, the dependent variable is the concentrated lactic acid and that of NAD+.
In order to increase the validity of the experiment, the Researcher can make use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
They live in the Winter climate
Answer:
Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.
Example for animals: Animals using glucose and oxygen in diffusion.
Examples for plants: Plants using carbon dioxide to photosynthesize.
