The right answer is a. they contain many small, repeating subunits bonded together.
In chemistry and biology, a polymer is a molecule made up of a chain of similar molecules, called monomers; a polymer is a macromolecule resulting from the assembly of many identical units (monomers), a chemical compound with repetitive structural units.
DNA, glycogen and proteins are polymers
The cycle runs like this:
Deoxygenated blood enters from the body to the heart via the superior/inferior vena cava. It goes directly to the right atrium and down to the right ventricle. From there it'll pass through the pulmonary artery into the lungs where diffusion will happen in the capillaries. Gas exchanges will occur and the blood will become oxygenated and return to the heart via the pulmonary vein. From the pulmonary vein it will enter back into the left atrium and then will give the final pump of oxygen rich blood into the aorta and then into the entire body.
Answer:
I believe c not completely sur e though
Explanation:
The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.
<h3>What is population dynamics?</h3>
Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.
Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.
With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.
