Answer:
1. Glucose is the simple food which is prepared first in the process of photosynthesis.
Glucose and oxygen are the final products of photosynthesis.
Starch is the food that gets stored in plant leaves.
2. In Amoeba, digestive juices are secreted in the food vacuole, which act on the food and break it down into simpler form.
Gradually, the food is absorbed. In the same way, in human beings, digestive juices secreted by various body organs (e.g., mouth, stomach, intestine, etc.)
3. How is food digested.
Digestion involves the mixing of food, its movement through the digestive tract, and the chemical breakdown of the large molecules of food into smaller molecules.
Digestion begins in the mouth, when we chew and swallow, and is completed in the small intestine.
4. Wastewater released by houses is called sewage.
5. (a) Solid water – ice is frozen water. When water freezes, its molecules move farther apart, making ice less dense than water. ...
(b) Liquid water is wet and fluid. ...
(c) Water as a gas – vapor is always present in the air around us.
6. Cleaning of water is a process of removing pollutants before it enters a water body or is reused.
This process of wastewater treatment is commonly known as Sewage Treatment.
It takes place in several stages.
Cleaning of water is a process of removing pollutants before it enters a water body or is reused.
7. Water in aquifers is brought to the surface naturally through a spring or can be discharged into lakes and streams.
Groundwater can also be extracted through a well drilled into the aquifer.
A well is a pipe in the ground that fills with groundwater.
This water can be brought to the surface by a pump.
8. (a) Oils and fats should not be released in drains because they harden the soil in the sewage pipes and block them. Fats get clogged in holes of the soil in the drain and block it. It does not allow the water to flow. ...
(b) Hence Drains get blocked by cooking oils and fats.
(c) Drains get blocked by cooking oils and fats.
9. Liver: is the largest gland in body.
It stores its waste bile in Gall Bladder.
Bile is released into duodenum and helps in digestion of fats.
Liver secretion, bile, does not have any enzymes in it.
10. A drought is defined as "a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the affected area." -Glossary of Meteorology (1959).
