One way to identify bacteria is using Gram Staining.
---
<span>The bacteria are stained with a purple dye (Crystal Violet). Though, most bacteria are then stained red. The bacteria are stained again with Potassium Iodide, then t<span>he bacteria are then washed with alcohol.
The bacteria that keep the dye after washing is known as Gram Positive bacteria. Likewise, those who don't keep the dye are Gram Negative bacteria. </span><span>The bacteria are further stained with a pink dye (Safranin). Gram Negative bacteria will go pink after this dying, whereas Gram Positive bacteria will remain purple, from the original purple dye.
Then there is </span></span><span>Ziehl-Neelsen Staining, also known as acid-fast staining. It's necessary as all mycobacteria have waxy coats on their cell walls that Gram Staining can't touch. All Mycobacteria test positive with this test, so, unfortunately, you cannot differentiate different species of Mycobacteria. </span>
Answer:
Decayed organic matter provides nutrients to other organisms
Explanation:
Genes are the proof of evolution and show that we are related to another species that existed long ago. So that means we all share some of the same genes.
Answer:
ATP releases energy (ATP + H2O --> ADP + P + energy) and in order for things like active transport to happen ATP is required.
Answer:
A copy of DNA is passed on to new offspring.
Replication is the process by which DNA is copied.
Explanation:
During cell division, the DNA molecule in the parent cell must replicate accurately before the cell divides. The two strands are believed to separate. Each strand becomes a template that specifies the base sequence of a new complementary strand. Through the action of replicating enzymes, free nucleotides come and take up positions along the template strands. Covalent bonds are then formed between the new nucleotides resulting in formation of new DNA strand.
