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.
Answer:
Smooth muscle fibers have an oblong shape, much like a football. They’re also thousands of times shorter than skeletal muscle fibers. Similar to skeletal muscles, cardiac muscles are striated. They’re only found in the heart. Cardiac muscle fibers have some unique features.
Explanation:
Answer: Option A
Explanation:
A tunicate is marine invertebrate animal which is a part of chordates. They have notochords and dorsal nerve chord. The subphylum of the organism is called as Urochordata.
The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.
The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.
