One of the first modern chemotherapeutic agents was sulfonamides which acts as a competitive inhibitor to an enzyme involved in folate synthesis.
Sulfonamides are sulfa drugs that were very first modern antimicrobial drugs that are synthetic. Human beings can not make folic acid themselves and need enzymes to synthesize it. Microbes can, they have the enzymes for it. We target those enzymes with sulfonamides and trimethoprim-competitive inhibition.
It is supplied to cells in high concentrations to make sure enzyme is constantly occupied rather than the true substrate of the enzyme.
Both of them (tortoises and anoles) represent examples of evolution observed by different scientist.
Darwin proposed that animals such as Galapagos tortoises changed as they adapted to new environments and this observation led to his theory of evolution by natural selection.
On the other hand, Losos observations were anoles of the Caribbean islands. He noticed that physical characteristics of those animals changed in response to their environment change. The traits that changed were the ones that affect the survival of anoles. Losos also concluded that the similar lizards that are not closely related, but were similar evolved separately in response to their environment. This is known as convergent evolution.
Answer:
The slime mold is a protists, not a fungus. However, it has a similar appearance as a fungus but a different cell wall composition.
Explanation:
Slime mold is protist not a fungus. It is due to the composition of the cell wall. The cell wall of fungi is composed of chitin while cell wall of slime mold is made up of cellulose. The other characteristic of slime mold is the movement. They can move from one place to another like animals.
Monomers are molecules whose linkage between them form polymers.
<h3>What are monomers?</h3>
Monomers are molecules that have a low molecular mass.
<h3>Characteristics of monomers</h3>
- When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.
- Natural monomers allow the formation of biomolecules found in living beings.
- Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).
Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.
