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.
The answer is absorbing dead or decaying organisms
1.
Han Solo genotype: ff
Offspring genotypes: Ff, ff
There is a 50% chance the child will have the force.
2.
Let f be webbed feet and F be non-webbed feet
Parental genotypes: ff ; FF
Possibility of webbed feet in offspring: 0%
3.
Yes, it is possible if both parents are heterozygous. 25% of offspring will be grey.
4.
Pheonotypes: Hairy and non-hairy fur
genotypes: HH, Hh, hh
5.
Parental genotypes: RR and RL
Offspring phenotypes: Brown hair and Brown and Black hair
Offspring genotypes: RR, RL
6.
Genotypes: BW
Phenotypes: Grey
7.
Black
8.
None of his children will be bald.<span />
