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.

but idk, i only know that eukaryas have membranes around nucleus and the other one doesn't
Answer:Cholecystokinin
Cholecystokinin stimulates the gallbladder to contract and release stored bile into the intestine.

Answer:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
