Well CO2 levels are high , and that’s a shift in their reaction. so i suppose when the person is sleeping their CO2 levels are lower so if there is an answer asking if it’s lower then press that if not i don’t know i’m sorry :/. if you ever need anything else DM me lol

vegetative propagation.

Budding and grafting. It is mainly used for propagating a plant. In layering sometimes the portion of the aerial stem grows roots while it is still attached to the main plant and then it is separated from the main plant and allowed to grow on its own. This is another technique used for layering.

Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?

daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

monomer/glucose glycosidic bond branching

1.starch α glucose 1-4 and 1-6 branch and unbranced

amylose 1-4 unbranched

amylopectin 1-4 and 1-6 branched

2. dextran α glucose 1-6 branched

3. cellulose β glucose 1-4 unbranched, linear

4. glycogen α glucose 1-4 and 1-6 branched (shorter

branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.

Compare and contrast saturated and unsaturated fats

gogolik [260]

Saturated fats are bonded together by single bonds, are found in animals, and are solid at room temperature; unsaturated fats are bonded together by double bonds that create a “kink”/bend, are found in plants, and are liquid or oil at room temperature.
