Describe how scent and taste work in conjunction. Are the tastes of below mention foods that were tested heightened by the sense of smell, or only some of the foods? a. Salt
b. Sugar
c. Lemon Juice
d. Coffe grounds

Scent and Taste work in conjunction because when your brain smells food, it pulls up a picture or memory of that food in your head, and you remember what it tasted like and if you enjoyed it.

Only some of the food. Salt does not really have a smell, so it does not do anything, but all the others do and are heightened

Explanation:

Take cotton candy for example. When you smell cotton candy, you smell SUGAR and lots of it. You know that sugar tastes good and as such you now want to eat the cotton candy.

For this example, we will use lemonade. Lemonade is commonly a drink that most love on a hot summer day at the beach. When you smell the lemonade, it reminds your brain of how good it tasted and pulls up the memory at the back of your mind,  making you feel happy and relaxed. It then ends up tasting better

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
