Answer:
B. they are pumped by proteins that require ATP hydrolysis and when the electrical charge gradient repulses or attracts them
Explanation:
Hello,
Ions move in the direction opposite to that favored by the chemical concentration gradient when they are pumped by proteins that require ATP hydrolysis and when the electrical charge gradient repulses or attracts them because active pumping moves ions against their chemical concentration gradients and the Nernst equation describes how membrane potentials can yield electrical gradients to motivate ion movement.
Best regards.
Answer- The correct answer is ammonia.
Explanation- All other compounds that are formed do not have any essence of Nitrogen in it. Whereas, Methane is a compound with carbon and hydrogen as elements while water has hydrogen and oxygen as its elements.
Lastly Hydrogen and chlorine combined together to form hydrochloric acid. Hence the only compound left with nitrogen is ammonia and has nitrogen and hydrogen as its basic elements.
It’s A because bleach doesn’t sting on touch and you can’t taste it
The chemical formula C₂H₆O, which is designated as option D, is equivalent to this structural formula.
<h3><u>What is a Chemical Formula ?</u></h3>
Chemical element symbols, numbers, and occasionally additional symbols like parentheses, dashes, brackets, commas, and plus (+) and minus () signs are used in a chemical formula to represent information about the chemical proportions of the atoms that make up a certain chemical compound or molecule.
- An empirical formula represents by symbols, such as Na for sodium and Cl for chlorine, with subscripts that show the relative number of atoms in each.
- The composition of any member of an entire class of compounds can be represented by a general formula, a sort of empirical formula.
