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:
Water-The entire process of water cycle takes place in almost five steps which includes the evaporation, condensation, precipitation, infiltration, and runoff. To begin with, water gets evaporated from the water bodies on the surface of earth like rivers, oceans etc. into the overlying atmosphere.
Nitrogen-The nitrogen cycle is split up into five main processes. These processes are nitrogen fixation, assimilation, ammonification, nitrification, and denitrification. Each of these play an important role in movement of nitrogen through the different ecosystems on earth.
Answer: They do this to obtain the vital nitrogen that they need to grow.
Explanation:
Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
they might conserve water
