Subunits are called nucleotides
Answer:
C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced
Explanation:
The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.
Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.
Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
Answer:
When the plates are at the mid ocean ridges thay are spreading apart creating new ocean floor. this is also called a divergent boundary
Answer:
The correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
Explanation:
The plant cell has a rigid cell wall that provides support to the plant cell that is not the case in the animals as they lack the cell wall. The low tidewater is an example of the hypotonic solution as it has fewer solutes than the plant cells or animal cells.
When a plant cell is in freshwater it takes up the water with the help of osmosis and begins to swell but the cell wall does not let it burst and become turgid.
Thus, the correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
When using the term 'life form' I assume you are speaking of animals, bacteria, etc. Scientists take years to find their desired conclusion because of how the environment tends to change quite frequently (Depending on where the creature lives). The earth is constantly revolving and rotating, which causes changes in the environment. These changes affect the animals behavior, eating habits, and overall chances of survival. A factor that must also be considered is that scientists have to examine these creatures in their natural habitat which can be an issue depending on where they live. For example, if I were to study the behavioral patterns of a Leopard, it would be extremely difficult to do so because the Leopards are specifically keen at camouflaging in their environment. That would make observing its behavioral patterns very frustrating and time consuming. In a way, mother nature is always against us.
(Hope this helps)
