Answer:Oxygen
Explanation: During cellular respiration, glucose is broken down in the presence of oxygen to form carbon dioxide, water and energy. Glucose + oxygen --> carbon dioxide + water + energy.
The balanced chemical equation for cellular respiration is C6H12O2 + 6O2 --> 6CO2+ 6H2O + Energy
Answer: A. ancestral trait
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.

"Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells."
Answer:
Plants and animals
Explanation:
Cellular respiration occurs in the mitochondria, known as the "powerhouse of the cell." Since both plants and animals require energy and have mitochondrion, they will both perform cellular respiration.
