Answer:
Reabsorption takes place mainly in the proximal convoluted tubule of the nephron .
Answer:
A. ATP
B. Yes, protons move with the concentration gradient
C. proton gradient across mitochondrial and chloroplast membrane.
Explanation:
A. During cellular respiration and photosynthesis, the free energy produced by the flow of electrons across the mitochondrial membrane and stroma lamellae leads to the formation of ATP molecule.
B. Due to the movement of electron down the reducing equivalent causes the flow of protons across the membrane. This leads to the formation of a concentration gradient.
C. The energy which drives the formation of ATP from ADP comes from the kinetic energy provided by the movement of protons across ATP synthase.
D. The back-flow of protons from intermembrane space of mitochondria to the matrix through ATP synthase and backflow from thylakoid lumen to stroma through ATP synthase add Pi to ADP and form ATP.
Answer:
30 percent tree cover - 2000 - 2009JPEG ... of forest cover vary widely—as much as 6 percent of Earth's land area, or the equivalent area of China.
Explanation:
Answer:
The genotype of the Dad must be X^AY because that's the only possible genotype for a normal male.
The genotype of the mom must be X^AX^a because that's the only way to have a colorblind son while being a normal mom. The colorblind son gets a Y from his dad and X^a from his mom.
The genotype ratio among the children must be 25% heterozygous dominant, 50% homozygous dominant, and 25% heterozygous recessive.
The phenotype ratio among the children must be 75% normal and 25% colorblind.
