The answer is electron transport chain. It is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples the electron transfer with the transfer of protons across a membrane. Electrons are transferred from NADH and FADH2 (proton donors) through the electron chain to oxygen, which is reduced to water. This process produces 34 ATP molecules and water from the carrier molecules.
Experimental design refers to how participants are allocated to the different groups in an experiment. Types of design include repeated measures, independent groups, and matched pairs designs.
I think the answer is probably A because the population will eventually start to reproduce
D, the theory has been built up with evidence over time.
Answer:
- Determine what information is required to collect
- Determine the methodology used for data collection
- Determine the methodology used for analyzing data
Explanation:
Data collection is the process of obtaining and measuring information on a variable of interest, which is used to answer questions about a particular issue and to obtain conclusions by the evaluation of the outcomes. Data collection represents an important issue from a broad spectrum ranging from social sciences to physical/natural sciences, as well as in business structures. For example, in an international company, such data collection enables to save money by building customer's databases that help to reduce marketing efforts. Methodologies for data collection include observational procedures, interviews, questionnaires and group discussions.
