The answer is (b.) Fine Pebbles have a higher threshold velocity than sand.
Given the fact that fine pebbles' diameter size are usually 2.0 to 5.0 mm which is bigger compared to sands which diameter is usually measure only at 0.05 to 2.0 mm, thus fine pebbles have higher threshold velocity than sand. In Geophysics, threshold velocity refers to the minimum velocity of a particle such as pebbles and sand to move by the cause of wind or water. Therefore, the higher threshold velocity is the fine pebble since it is bigger.
Answer;
Sister chromatids may drift apart after being synthesized.
Explanation;
-Cohesin is a protein which localizes between the sister chromatids and holds them together to resist the pull of the kinetochore microtubules.
-Because cohesin enables sister chromatids to remain attached from the time they are synthesized during S phase until the end of metaphase. If cohesin is defective, sister chromatids may separate before they normally would in anaphase, which would lead to daughter cells that have too few or too many chromosomes.
Answer and Explanation:
Hydrogen ions in the thylakoid space form an electrochemical gradient because of the difference in the concentration of protons (H+) and the difference in the charge across the membrane that they create. This potential energy is stored as chemical energy in ATP through chemiosmosis. The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. Energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space. The photon causes an electron in the chlorophyll to become excited.
