GaryK [48]
<h2>The correct answer is: Mutualism.</h2>

Explanation:

  • Mutualism can be defined as a type of symbiotic relationship.
  • Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
  • Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
  • In the given question, some micro-organisms survive in the digestive tract of the cattle.
  • These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
  • On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.

When you eat salmon for dinner, your digestive system will break down that food
zimovet [89]

Answer:   c. Amino Acids

Explanation:

Food is chemically and mechanically broken down into smaller particles like building blocks, the smallest of these are a basic unit called monomers. In the <em>stomach</em>, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. The <em>duodenum</em> processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acid monomers for absorption into the bloodstream via the small intestines.

Strike441 [17]

The simulation supports the scientific law : I.e TRUE

<h3>The scientific law of conservation of mass</h3>

The scientific law of conservation of mass states that the mass of a substance remains the same in a closed system  as the substance/matter undergoes a chemical reaction. during chemical reaction the matter changes from one form to another. Therefore measuring the mass of matter in an object before it undergoes a chemical reaction support the scientific law as the mass of reactants is equal to mass of product.

Hence we can conclude that the simulation supports the scientific law : I.e TRUE.
