Name four behaviors that animals must use to survive


Answer 1
Answer: Smelling, seeing, quickness, stealth
Answer 2


Understanding how genes and the environment come together to shape animal behavior is also an important underpinning of the field. Genes capture the evolutionary responses of prior populations to selection on behavior. ... Many scientists study animal behavior because it sheds light on human beings.

What type of biological molecule is catalase?


Catalase is a common enzyme found in nearly all living organisms exposed to oxygen.

Final answer:

Catalase is an enzyme, a type of biological molecule composed mostly of protein, that serves as a catalyst to accelerate the breakdown of hydrogen peroxide into water and oxygen within living organisms.


Catalase is a type of biological molecule called an enzyme. Enzymes are macromolecules, primarily composed of proteins, that act as catalysts to accelerate chemical reactions within living organisms. They work by lowering the activation energy of the reaction they are catalyzing, thereby speeding up the reaction rate. Catalase serves a critical biological function by converting the harmful substance hydrogen peroxide into water and oxygen.

Enzymes function by binding to reactant molecules and facilitating bond changes in order to make the reaction occur more readily. However, they do not change the reactants' or products' free energy or alter the direction of the reaction. Instead, they simply reduce the activation energy required to reach the transition state of a chemical reaction.

Like all enzymes, catalase is highly specific to its substrate (the molecule it reacts with). In this case, the substrate is hydrogen peroxide. Importantly, like all catalysts, enzymes including catalase do not get consumed or modified during the reaction, making them reusable.

How does the respiratory system interact with the circulatory system?A)The respiratory system transports oxygen and other nutrients to the heart for the circulatory system.

B)The respiratory system brings in carbon dioxide so the circulatory system can transport it throughout the body.

C)The circulatory system transports nutrients and oxygen brought in by the respiratory system throughout the body.

D)The circulatory system removes oxygen and other nutrients from the body to make room for carbon dioxide in the respiratory system.


C. Oxygen and nutrients taken in by the respiratory system are transported to the circulatory system for transport around the entire body.
Also, B and D cannot be correct, as carbon dioxide is not wanted in the body (it's a waste product of respiration of the body cells)
