Answer:
Planet B is expected to be cooler than Planet A.
Explanation:
In the given case, planet A is closer to the star than planet B. Their atmospheric conditions and mass is same so their surface temperature will depend on their distance from the star. Since planet A is closer, it will receive more radiation from the star. In turn it will be hotter to re-radiate that energy back to space. Hence, average surface temperature of planet B will be lower than planet A.
<span>Choices (b) and (c) are the most correct. Bilateral symmetry requires a central axis for there to be two halves. In addition, this type of symmetry requires a head, which will encounter the environment before any other part of the body and move in the direction of travel. Most animals exhibit this characteristic.</span>
Explanation:
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: 2 H2O → 2 H2 + O. Efficient and economical photochemical water splitting would be a technological breakthrough that could underpin a hydrogen economy.
