I'm sure this is the answer
Answer: 30. D. Cell
31. A. Tissue
32. D. Biome
33. A. Population
34. D. Condensation
35. B. Precipitation
Explanation:
30. A cell is a largest component of life among the options given. As it includes within it molecule, and organelles required for the functioning and metabolism of cell.
31. A tissue is the smallest component of life. It is made up of group of cells. The cells combine together in tissue to perform a specialized function in organisms.
32. Biome is the largest ecological group which includes diversity of living organisms interacting with the physical environment. The biome is characterised by abiotic factors like climate, temperature, geography, and soil and also by the biotic factors such as flora and fauna.
33. Population is the smallest group which includes the members belonging to the same species living in the same location or region. These members are capable of inbreeding among themselves and producing viable offsprings.
34. Condensation is a process in which the water vapors being in high temperature cools down in the sky to form clouds. It is the part of water cycle.
35. Precipitation is the part of the water cycle. In this the clouds formed after the condensation process, due to increase in amount of water vapors in them the water falls off under the effect of gravity. The precipitation is in the form of sleet, snow, hail, drizzle and rain.
The correct answer is: Protons are pumped out of the mitochondrial matrix into the intermembrane space
Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).
Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.
H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.
Well, it depends but adults can weigh up to 420,000 pounds
