Answer:
A proton Pump, using ATP, pumps protons outside
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
pH decreases;
The gradient becomes sufficient.
H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.
Explanation:
A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease
At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.
H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.
Answer:
Freshwater biomes are large areas consisting of plants and animals grouped around water with "less than 1% salt concentration." This includes lakes, rivers, ponds, streams, and some types of wetlands.
Answer:
C. The moon's gravitational pull and Earth's rotation
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Answer:
missing - biostatics
Explanation:
Longitudinal studies differ from one-off, or cross-sectional, studies. The main difference is that cross-sectional studies interview a fresh sample of people each time they are carried out, whereas longitudinal studies follow the same sample of people over time.

Answer:
Double Helix
Explanation:
It is called the double helix for the signature shape that a DNA strand takes.
