There is an uneven distribution of electrons between oxygen & hydrogen atoms
Answer: "To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells."
The answer is nitrogen fixation.

Answer: C) The subplate neurons attract the appropriate thalamic axons to the different parts.
Explanation:
Subplate neurons are the first developed neurons can be found in the cortex of mammals. These neurons disappear during the process of postnatal development and due to functional maturation.
These neurons are sensitive to the injury, when the humans experience cognitive and motor defects.
These neurons attract the thalamic axons and receive the synaptic inputs through the thalamic axons thus helps in establishing the link between the thalamic axons and the target layer IV. The signals are distributed from the thalamic axons to different parts of the body.
Answer:
The answer is C.
Explanation:
Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.
The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.
Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.
Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.
Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.
I hope this answer helps.
