Answer:
The correct answer is option c. "formation of protocells that use DNA to direct the polymerization of amino acids".
Explanation:
The polymerization of amino acids is a complex biological function that involves multiple proteins and cofactors working together at different locations in the cell. Even though there are some scientific advances in the production of synthetic protocells (cell like structures made from synthetic particles), the formation of protocells able to synthesize amino acids from DNA directly has not been accomplished.
Answer:
A trophic level is a level of an organism in the food web, and can be a producer, primary consumer, secondary consumer, apex predator, decomposer, etc.
Answer:
The effects of high altitude on humans are considerable. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 meters (6,900 ft) above sea level, the saturation of oxyhemoglobin begins to decrease There’s oxygen in the air at high altitude. An increase in red blood cells in their bodies allows people to increase their body oxygen levels, especially when they perform strenuous exercise at high altitudes. Many athletes will train at high altitudes in preparation for competitions at lower altitudes. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 meters (26,000 ft) as the death zone, where it is generally believed that no human body can acclimatize
