Answer:
c. More oxygen and less carbon dioxide
Explanation:
The composition of air in the layers between the soil is called soil atmosphere or gas.
The maximum percentage of gas in soil is nitrogen with 79.2 %. Then it is oxygen with 20.6 % and the last is carbon dioxide with 0.25 %. These gases are required in order to maintain life under the ground. The roots of trees and the microorganisms require soil atmosphere to carry out their functions.
The Nucleus contains most of the genetic information for making proteins
The ribosome is the place where the polypeptide strand and the mRNA meet in order to create a protein
Nucleolus has a role in the biogenesis of the ribosomes
RER -intracelular transport and protein making because of the attached ribosomes
SER-intracelular transport,lipid synthesis and it is the place where the glicogen is metabolized
Golgi Apparatus has a secretive role
Lysosomes contain 40+ hydrolytic enzimes that help with intracelular digestion
Cilia and flagella both help with the moving of the cell
Extracellular matrix keeps the cells together
The Mitochondria sythesizes ATP in a process caled oxidative phosphorylation of organic substances
<h2>Answer:</h2>
Salivary amylase breaks the chemical bonds of starch to form sugar monomers.
<h3>Explanation:</h3>
- Amylase is one of the digestive enzymes which catalyze the breakdown of starch molecules into its monomers.
- A starch molecule is made of the Glucose molecules which are bonded with each other with glycosidic linkages.
- Salivary glands secrete saliva into the mouth cavity.
- Saliva contains amylase for the digestion of starch are known as salivary amylase.
- Steps in the digestion of sugars start from the action of this enzyme.
