Please answer these questions
Answers
1) photosynthesis
2)guard cell
3) fishes die when they are taken out of water because they can not breath as they can not take the oxygen present in the atmosphere.
4) pepsin
5) glycolysis
6)common for cuscuta ticks and leeches is that they are parasites.
7) small intestine is the site of complete digestion of our body
Carbohydrate are converted into monosaccharides like glucose,
Proteins are converted into amino acids and fats are converted into fatty acids and glycerol.

mark as brainalist. if it helps u
Answer:
1) Photosynthesis
2)Guard cells
3) Fishes generally live in water bodies and a respiratory organs gills which is used to observe the dissolved oxygen present in water.but when the fish is taken out of water the only oxygen available for respiration is the oxygen present in the atmosphere but the fish has no special organs to breathe in land. Due absence of lungs which helps in exchange of gases in terrestrial environment the fish dies.
4) The enzyme secreted by the stomach to digest proteins is pepsinogen which is in inactive state .On exposure to hydrochloric acid secreted in the stomach ,it converts itself into pepsin which is active.
5) Glycolysis is the common step for both aerobic and anaerobic respiration. Glycolysis results in the breakdown of one glucose molecule into two moles of pyruvic acid.
In aerobic respiration pyruvic acid is broken down into carbon dioxide molecules whereas in anaerobic respiration pyruvic acid is broken down into acid or alcohol
6) All of them are ectoparasites that is they live on the host body and obtain all nutrients from the host.
Ecto - live externally.
7)site of complete digestion is small intestine more appropriately duodenum of the small intestine.
End products of digestion.
Carbohydrates - simple sugars like glucose ,fructose.
Proteins - amino acids
Fats - simple fatty acids and glycerol.
Hope it helps you!!
