Briefly outline the progressive evolution of the respiratory and circulatory systems in vertebrates
nikitadnepr [17]

The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. Made of specialized and unique cardiac muscle, it pumps blood throughout the body and to the heart itself.

Claps shut at birth. Evolutionary changes in the vertebrate heart are tied to change from single to double-circuit heart, with increased separation of oxygenated and deoxygenated blood, allowing more efficient respiration and circulation to fuel high activity and increased oxygen demands associated with endothermy.

elena-14-01-66 [18.8K]

Explanation:

E, will be lower- this denotes the activation energy

Activation energy is the specific amount of energy required for a chemical reaction to occur. Enzymes lower the activation energy, significantly speeding up the reaction rate.

Further Explanation:

Enzymes are proteins that catalyze reactions by working on substrates to promote reactions-including amylase breakdown of broad polysaccharides. Some enzymes like catalase, allow for the degradation of hydrogen peroxide into oxygen and hydrogen; the pH, temperature, and involvement of inhibitors influence their specificity.

The population will increase because the coyote population are eating all the deer and are bearing children!
