Answer: olfactory receptors
Sharks have highly developed olfactory receptors. The olfactory receptors in animals allows them to sense the odor. Sharks have olfactory receptors more sensitive than humans. They have nostrils located on the underside of their snout, which they use for smelling not for breathing. The smell of the prey animal or the blood of any animal is detected by the shark with the help of these receptors.
B. Movement of sugars within the xylem results from changes in concentration of water.
C. Transpiration is the only force that drives water movement within a plant.
D. Cohesion and adhesion contribute to capillary action, which contributes to water movement.
True or false
Answer:
False. When bonds are broken, energy is absorbed.
Explanation:
Atoms form bonds to seek stability, which means lower energy compared to when they were separated. This means that separating atoms by breaking bonds is not energetically favourable.
Therefore, in order to break a chemical bond we need to provide energy to the system, which makes the process endothermic (it absorbes energy).
The attached image shows an energy diagram for the H₂ molecule, showing the variation in energy during bond formation.
