Answer:
adaptations (based on natural selection)
Answer:
systematics is the correct answer.
Explanation:
- The modern approach to classification, with the broader goal of reconstructing the evolutionary history, or phylogeny, of organisms is: systematics.
- Systematics plays an important role in the field of biology.
- Carl Linnæus is the father of Systematics.
- Systematics refers to the study of the diversification,nomenclature, and classification of the living organism in the past and also in present.
- Systematics is used to understand the evolutionary relationship and the purpose of systematics is to describe and explain biological variety.
- The main objective of systematics is to identify species and to give scientific names to organisms, it used to determine the arrangement of the living organism and to study the evolutionary history of organisms.
Answer:
Hydrogen and electrons
Explanation:
Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.
For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
The purpose of the experiment is to test a hypothesis and draw a conclusion
