Answer:
The given statement is false because there is no involvement of solar energy during electron transport chain.
Explanation:
Solar energy is utilized in photosynthesis but not in electron transport chain(ETC).During ETC electrons are liberated from the reducing equivalent such as NADH,FADH2.The liberated electron moves from one electron carrier to another until it(electron) reaches the terminal electron acceptor oxygen.
The movement of electrons occur simultaneously with the movement of proton(H+) resulting in the generation of proton motive force(PMF). This proton motive force helps in the phosphorylation of ADP to form ATP with the reduction of o2 to water.
Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
Destruction of coral reefs would cause an imbalance in the ecosystem. Some species could be driven to extinction.
Coral reefs are the base of the most diverse marine ecosystem in the world. They are often referred to as the ‘rainforest’ of the oceans and seas. They provide shelter for cnidarians, sponges, crustaceans, and etcetera and provide hiding grounds from predators.
