Answer;
-Hydroxyl groups.
-They have multiple hydroxyl groups.
Explanation;
-Monosaccharides are the simplest form of sugars found in common food items such as honey, cane sugar, fruits. They are the building blocks of other carbohydrates (disaccharides and polysaccharides).
-The are formed by three elements and three elements only: Carbon (C), Hydrogen (H) and Oxygen (O). Monosaccharides have two broad classifications on the basis of the functional group present in them, that is; aldose (contains aldehyde group) and ketose (contains a keto group).
-Monosaccharides contain multiple hydroxyl groups, and are responsible for the hydrophillic property of monosaccharides allowing them to dissolve in water easily.
Answer:
C. extinction
Explanation:
For example, you have a dog that naturally salivates at the sight of food. The salivation is an unconditioned response that is generated by the an unconditioned stimulus which is the food you present to your dog.
If you decide to ring bell before presenting food to your dog, your dog would associate the sound of the bell with food. And each time you ring the bell, your dog would salivate even when food is not presented. This salivation is a conditioned response that is generated when a conditioned stimulus (sound of the bell) is presented.
If the conditioned stimulus (sound of the bell) is presented repeatedly to your dog without the unconditioned stimulus (food), extinction occurs. Meaning your dog would stop salivating when next it hears the sound of the bell over time. The association of the sound of the bell with food by your dog would be weakened and goes to extinct over time.
<u>Answer</u>:
Different types of magnifying technology like light microscopy and electron microscopy helped scientist to determine differences in the internal structures of plant and animal cells.
<u>Explanation</u>:
Human eyes can only see up to 1 mm in range. Plants and animal cells are very small which cannot be seen by the naked eye. For this reason, microscopes have been used to see enlarged structures of cells with the help of a compound microscope or electron microscope.
Light microscope can only magnify up to 1000x time to see the details of the cell but electron microscopes can magnify up to 100,000x times. The cells to be examined for the internal structures are cut into fine slices with the help of ultramicrotome and visualized under transformation or scanning electron microscope.
