Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.
Answer:

it would be A
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

<u>Answer</u>:
Neutral molecules are the products of the hydrolysis reaction.
<u>Explanation</u>:
Hydrolysis reactions are double decomposition reactions. In these reactions water reacts to the ester linkage in a molecule resulting into the breaking of bond between the elements of the molecules.
The products those result include the one which receives the hydroxyl (OH) group from the reacting water molecule and another one receives the remaining proton (H+). For example, if AB is a compound in which A and B are atoms or groups after the hydrolysis reaction with a water molecule (HOH) the products of this reaction may be the neutral molecules represented by the given reversible chemical equation i.e. AB + HOH ⇌ AH + BOH.
As prey increase predatory increase and as prey decrease due to the increase of predators. The number of predators will decrease due to the lack of foods.
