Explanation:
Bipedalism can be define as a form of terrestrial locomotion, in which the organism moves with the help of two rear limbs or legs. Typical bipedal movements includes the hoping, running and walking. The evolution of the human bipedalism occurred in primates in about 4 million years ago with Sahelanthropus (oldest human ancestors or African Apes). The human ancestor Sahelanthropus led to the morphological alterations in the human skeleton including changes in the bones such as size of the bones of the foot, knee size, shape and orientation of the vertebral column, and leg length. All these changes contributed to the bipedalism.

Explanation:
Excitation of photosystems by light energy, Production of ATP via an electron transport chain and reduction of NADP+ and the photolysis of water are the correct order of thylakoid reaction.
<h3>What are the three stages of thylakoid reaction?</h3>
These reactions occur within specialized membrane discs within the chloroplast called thylakoids. It consists of three steps.
- Excitation of photosystems by light energy.
- Production of ATP through an electron transport chain.
- Reduction of NADP+ and the photolysis of water.
