A tetrad consists of 2 homologous chromosomes each of which is made up of 2 sister chromatids
Answer: c. 2 pyruvate molecules
Explanation:
Glycolysis is the first step it the cell respiration cycle. It turns one molecule of glucose into two molecules of pyruvate by a series of reactions catalyzed by different enzymes.
It starts by using 2 ATP to turn glucose into fructose-1,6-bisphosphate, which then divides in two and releases 4 ATP when it turns into two pyruvate molecules.
Thus glycolysis consumes 2 ATP and releases 4 ATP (giving a net gain of 2 ATP) and 2 pyruvate molecules.
Answer:
contour farming
Explanation:
Contour farming is the method of growing crops on sides of hills, mountains and steep slopes by planting on graduated terraces built into the slope. This method effectively reduce soil erosion and water loss and maximizes arable land area. In most of the systems the contours are low, flat ridge of earth built across the slope, with a channel for runoff water just above the ridge. In areas where soils are able to take in water and rainfall amount is relatively low, level terraces may be used to reduce soil erosion too.
Carnivores (meat eaters): lion, wolf, polar bear. herbivores (plant eaters): cows, beaver, deer. omnivores (both meat and plant eaters): bears, humans, hedgehogs.
