They might have a common ancestor.
B. synapomorphy
A synapomorphy is a shared apomorphy that distinguishes a clade from other organisms.
A clade also known as monophyletic group, is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life".
Answer:
It is the biological concept of species
Explanation:
In 1970 Mayr stated that "species are formed by groups of potentially intercrossing populations that are reproductively isolated from others". The biological concept of species puts emphasis on existence of barriers that limit the gene flow among groups within the same species
Answer:
Aerobic respiration is a process glucose produces energy in the presence of oxygen. In this process glucose is oxidized to produce carbon dioxide, water and energy in the form of ATP.
C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + Energy (ATP)
Three main processes that make up aerobic respiration are:
1. Glycolysis: it takes place in the cytosol of the cell. Here, glucose is oxidized to form three carbon molecule pyruvate. This process produces energy in the form of 2 ATP molecules and 2 NADH molecules. These NADH molecules carries 2 energy electrons these electrons are utilized by the electron transport chain.
2. Kreb's cycle: it takes place in the cytoplasm and mitochondria of the cell. Here, the molecules of pyruvate produced during glycolysis is utilized to produce ATP.
3. Electron transport chain: glucose is not entirely converted into ATP. The NADH molecules produce during glycolysis produces 2 energy electrons these electrons are taken up by electron transport chain in the mitochondria inner matrix. A proton gradient develops across the matrix after donation of electrons to electron transport chain. This gradient in turn produces energy in the form of ATP.
