Answer: monosaccharides are simple sugars made up of only a single sugar molecule. Disaccharides are sugars made up of two sugar molecules linked together by a glycosidic bond while polysaccharides are complex sugars made up of many sugar molecules linked together by glycosidic bonds.
Explanation: Examples of monosaccharides are glucose, fructose, and galactose, while examples of disaccharide sugars include maltose, lactose and sucrose. Examples of polysaccharides include glycogen
and starch.
Answer:
99 to 138.6 bpm
Explanation:
The heart rate of an individual is a measure of how many times the heart beats in a given time, usually measured in beats per minute (bpm).
Resting heart rate is the number of beats per minute when an individual at rest. Generally, it can be understood that the lower the resting heart rate, the more physically fit an individual is.
The maximum heart rate for an individual is 220 minus their age. The target heart rate for moderate physical activity is 50-70% of the maximum heart rate and for vigorous physical activity it is 70-85% of the maximum heart rate.
Based on Holly's age, her maximum heart rate is 220 - 22 = 198 bpm
Her heart rate zone for moderate physical activity is 50-70% of 198 bpm: 99 to 138.6 bpm
Her heart rate zone for vigorous physical activity is 70-85% of 198 bpm: 138.6 to 168.3 bpm
Answer:
The correct answer is Active transport moves substances against the concentration gradient.
Explanation:
The principle difference between active transport and facilitated diffusion is that active transport helps in the movement of various substances in the uphill direction which means against the concentration gradient.
In simple words active transport helps in the movement of substance from the region of low concentration to a region of high concentration.
On the other hand during facilitated diffusion substances move along their concentration gradient which means from the high concentration region to the region of low concentration until the concentration of both sides become same.
