A= cell wall
B= cytoplasm
C= Plasmid
Answer:
Option A: True
Explanation:
Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.
As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.
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.
Answer:
Stored water - gravitational energy
Water fall - kinetic energy
Turbine - kinetic energy
Powerlines - electric energy
Explanation:
Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.
When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.
As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.
Kinetic energy is transformed to electric energy and transmitted along powerlines.
*See attachment below for labelled energy that is being transformed at several points.
