Answer:
64 g of O₂ is consumed in this reaction.
Explanation:
Mass of H₂O = 72 g
Mass of H₂ = 8 g
So, mass of O₂ consumed = mass of H₂O - mass of H₂ = 72 - 8 = 64 g
64 g of O₂ is consumed in this reaction.
The bear population would increase. The bears would have enough food to support more cubs/bears.
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
Answer:
Option (2).
Explanation:
The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.
The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.
Thus, the correct answer is option (2).
Answer: Microfilaments assist with cell movement and are made of a protein called actin. Actin works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. Microfilaments keep organelles in place within the cell.
