Cellular respiration included the metabolic pathways of glycolysis, the Krebs cycle, and the electron transport chain is described below.
Explanation:
1. Catabolism of glucose in glycolysis and pyruvate oxidation-Produces NADH for use in ETC.Produces acetyl-CoA for entry into kerbs cycle.Provides energy for phosphorylation of ADP.
2. Oxidation of intermediates in the Krebs cycle-Produces NADH or FADH2 for use in ETC.Releases high energy electrons for use in ETC.Provides energy to pump protons against their concentration gradient.Produces GTP for phosphorylation of ADP.
3. Formation of a proton gradient by the electron transport chain-The flow of protons through membrane-bound ATP synthase generates ATP.Provides energy for phosphorylation of ADP.
A fetus is still a developing organism inside the womb so the circulation differs due to the difference in the environment the organism is in, while the baby adapts to the surroundings around it from the womb its circulation changes
9) Andromeda Galaxy is blue shifting when viewed from earth
The answer is :
A population of birds with red feathers slowly changes to having blue feathers
Microevolution is a change in allele frequencies and can be caused by mutations, selection (natural and artificial), gene flow or genetic drift.
What's different from macroevolution is that this change happens over a shorter time when compared to macroevolution which is when big differences in the population happen.
From the options, a change in the colors of fethers seems like a microevolution that happened due to a mutation in the population over a period of time.
