Answer:
Greenhouse gases absorb radiation from the sun and re-radiate it back toward the <u>atmosphere,</u> which helps to maintain a normal range of <u>temperature</u> on Earth.
Greenhouse are glass house which are used to grow crops in regions exhibiting extreme cold temperatures and snow fall. The soil in these regions are frozen therefore, are not suitable for plant growth. These glass houses trap the sunlight which is used by the plants for photosynthesis and growth. Some gases like methane, carbon dioxide, carbon monoxide, sulphur and nitrogen dioxide are released into the atmosphere. These gases maintains the range of temperature of atmosphere.
Answer:
plant cells have a rigid cell wall that helps it keep shape and animal cells don't
Answer:
Enzymes speedup the chemical reaction.
Explanation:
Enzymes are the molecules which are responsible for speedup of the chemical reaction. In this picture, we can see substrate attached to the active site of the enzyme. This enzyme speedup the chemical reaction and products are formed after completion of chemical reaction. When the chemical reaction is over, the products detached from the enzyme and no decrease occurs in the size of enzyme.
Answer:
Chitin, Cellulose and Peptidoglycan (B, C and D)
Explanation:
Both chitin and cellulose are composed mainly of glucides, bound by glycosidic bonds of the Beta 1-4 type. This is largely why they cannot be digested by most non-herbivorous animals.
As for peptidoglycans, it is a net. It is a molecular framework present in bacteria that has β1-4 and α1-4 bonds in different proportions.
