In order to be classified as a living thing an organism must share or have the characteristics that define for what a living thing is ought to be, can grow and develop, can respond to stimuli in the environment, and more.
The most fundamental are that organisms must be composed of cells, regardless whether that it is prokaryotic and or eukaryotic. All living things must be made of cells.
Fish has a singular circulatory system, means the blood carrying oxygen from pulmonary circuit will be dumped into the same chamber as the blood carrying wastes and CO2 in the heart, because the heart has only one chamber.
amphibians has a 3 chamber heart, but still not a complete separated pulmonary circulation. However, it does have 2 loops at this stage. Of course birds and mammal also has this feature. So the distinction will be between fish and amphibian, which is the evolutionary double loop pathway.
Answer:
Proteins are a class of macromolecules that perform a diverse range of functions for the cell. They help in metabolism by providing structural support and by acting as enzymes, carriers, or hormones. The building blocks of proteins (monomers) are amino acids
Explanation:
<u>Answer:</u>
Enzymes 'reduces the activation energy' of both Exergonic and Endergonic Reaction by acting as a catalyst.
<u>Explanation:</u>
- For example, in the case of 'carbonic anhydrase', enzymes act rapidly causing the chemicals to 'react 107 times faster' than they would normally.
- Enzymes are substrate specific meaning an enzyme working on one substance may not work on another.
- Function of the enzyme is identified by its 'shape of the protein' and arrangement of these molecules produces an area called activation site.
I don't know the answer sorry
