Answer: A high-pitched, singsongy vocalization means that an animal is non-threatening, peaceful or empathetic. Dogs even employ a higher pitch with us when they're trying to get the same message across, like when they whine when they see their owner.
Explanation:
Answer: His famous theory was that all the continents could stick together like pieces of puzzle.
Explanation:
The correct answer is 2 ATP, 2 NADH, 2 pyruvate.
Glycolysis will produce 2 NADH (reducing agents) from the 6th reaction involving the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate by the enzyme glyceraldehyde-3-phosphate dehydrogenase. 2 ATP and 2 pyruvate is yielded by the last reaction of glycolysis which is the conversion of phosphoenolpyruvate to pyruvate by the enzyme pyruvate kinase.
Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.
