Answer:
Hypothesis is ''With the increase of algae in the aquarium, fish population decreases''.
Explanation:
The main problem was that there is no need for 2 aquarium because there is no need for aquarium 1 which has no fish and aquarium 2 which has fishes but no algae. With the increase of algae in the aquarium, fish population decreases is the hypothesis for this experiment. Concentration of algae is the independent variable of the experiment because there is no effect on it in the experiment.

When meteoroids enter Earth's atmosphere at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
The parasympathetic nervous system responds when the body is relaxed and at rest while sympathetic nervous system is responsible for response to emergency situation.
Explanation:
- The sympathetic nervous system is called fight or flight division while the parasympathetic nervous system is the rest and digest division.
- The pre-ganglionic neurons of sympathetic nervous system arises from lumbar and thoracic regions of spinal chord while the preganglionic neurons of parasympathetic nervous system arises from the brain and sacral region of the spinal cord.
- The sympathetic nervous system decreases the activity of digestive system while the parasympathetic nervous system increases the activity of digestive system.
- Sympathetic nervous system dilates bronchioles while parasympathetic nervous system constricts bronchioles.
- Sympathetic nervous system increases blood pressure while parasympathetic nervous system usually do not effect blood pressure.
- Sympathetic nervous system increases heart rate while parasympathetic nervous system decreases heart rate.
Answer: Glycosidic bonds.
Explanation:d
Glycosidic bonds are covalent bonds that join monosaccharides or longer glucose chains to other monosaccharide or carbohydrates to form disaccharides, oligosaccharides and polysaccharides and are named according to the type of the atom present on the second carbohydrate to be linked. The bond is usually formed between the hemiacetal of the first carbohydrate and the functional group on the second molecule which could be Oxygen-, Nitrogen-Sulphur -, and Carbon -glycosidic bonds.
Examples of Polysaccharides are Cellulose Starch , Glycogen formed by the linkage of many long residue monosaccharides connected through glycosidic bonds.
