The answer is plankton are floaters. Plankton and nekton are both marine aquatic organisms. The main difference between the two is that plankton tend to float and be carried by water currents while nekton are organisms that swim against the current of the water. Plankton are passive swimmers while neekton are active swimmers.
Answer:
a. Mastication process and formation of bolus in the oral cavity
b. The contraction in the stomach breaks the food down into smaller pieces. These pieces are then moved to the small intestine.
c. In the small intestine, food particles are broken down into nutrients, fat, protein and carbohydrates which are absorbed into the bloodstream.
Explanation:
a. First step of digestive system functioning is the mastication process and formation of bolus in the oral cavity.
b. The contraction in stomach, with the help of digestive enzymes and acids, break the food down into smaller pieces. The small pieces of food are then released into the first part of the small intestine (duodenum).
c. In the small intestine, two enzymes released from pancreas and gall bladder break down the food particles into fats, proteins, and carbohydrates. Thereon, nutrients and carbohydrates, proteins and fats are absorbed into the bloodstream.
Answer:
c.The addition of a water molecule breaks a bond between sugar mono-mers.
Explanation:
Hydrolysis refers to reaction with water. When water molecules are added to carbohydrates, the bonds between the sugar monomers are broken. This is the chemical reaction known as hydrolysis reaction.
Generally, since carbohydrates are polymers we can say that hydrolysis reactions result in the breakdown of carbohydrate polymers into sugar monomers by using water molecules
The general theory is that mitochondria and chloroplasts began initially as separate cells that were "eaten" by larger cells, but not digested and simply passed on due to their advantages.<span />
