Answer:
Primary active transport
Explanation:
Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump is an example of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).
B. by the sharing of electrons
Answer choices A and C are incorrect because covalent bonds form as a result of electrons (protons are kind of irrelevant). Answer choice D is incorrect because it describes an ionic bond.
Further study topics: water polarity, hydrogen bonds, free radicals, valence electrons, and more!
Answer:
The answer is B. Relative humidity percentage will be 50 %.
Explanation:
Relative humidity is the percentage of water vapors in the air at a particular temperature compared to the how much it can hold at that temperature. if the relative humidity is high (100%) we feel hotter than the actual temperature because water will not evaporate due to air saturation. in this case as the real feel is 108 F at 96 F the relative humidity will be 50 %.
Answer:
identification
Explanation:
because identification means identifying, elaborating, exploring more about that field by identifying it.
They would expect only about 5 hours of darkness.
