Answer:
B
Explanation:
This macromolecule is DNA. Its stored genetic information in form of genes that translate to functional or structural proteins that make up an organism. The DNA double helix is unzipped by helicases enzymes into single strands. RNA polymerase transcribes the single strands into mRNA. The mRNA is then translated into proteins by ribosomes. This is called the central dogma (DNA RNA Proteins).
During cell division, the DNA is replicated into two copies and each copy goes to each of the two daughter cells preserving, more or less, the same genetic code to the new cells.
The name of the embedded protein that provides a channel for the hydrogen ions to pass through the membrane is ATP synthase.
ATP synthase is a protein that catalyzes the formation of the energy storage molecule adenosine triphosphate (ATP) using adenosine diphosphate (ADP) and inorganic phosphate (Pi). It is classified under ligases as it changes ADP by the formation of P-O bond (phosphodiester bond). ATP synthase is a molecular machine.
The overall reaction catalyzed by ATP synthase is:
ADP + Pi + 2H+(out) ⇌ ATP + H2O + 2H+(in)
The formation of ATP from ADP and Pi is energetically unfavorable and would normally proceed in the reverse direction. In order to drive this reaction forward, ATP synthase couples ATP synthesis during cellular respiration to an electrochemical gradient created by the difference in proton (H+) concentration across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria. During photosynthesis in plants, ATP is synthesized by ATP synthase using a proton gradient created in the thylakoid lumen through the thylakoid membrane and into the chloroplast stroma.

-Subduction causes the lithosphere to be recycled at plate boundaries
At destructive boundaries, tectonic plates collide, the denser plate gets subducted under the less dense plate. The subducted plate dives into the mantle, melts and is recycled.
Explanation:
At the constructive boundary, as two plates move away from each other, magma from the mantle rises to occupy the void. The magma cools to form new crust in between the two plates.
As new crust is formed at the constructive boundaries and old crust is destroyed at destructive boundaries this maintains a balance that ensures the crust is maintained more or less the same size over time. The only difference is that the crust shift position due to these tectonic plates movements driven by convection currents of the mantle.

Answer:
True
Explanation:
Some histones function as spools for the thread-like DNA to wrap around.

Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.
