Organisms
Explanation:
Come to think of it,what do organs form
Answer:
Exposure to the disease
Explanation:
Before vaccines, the only way to develop immunity to a disease was to be exposed to the disease-causing pathogen without being harmed by it. A good example of this is smallpox, which was also the first vaccine developed. It was noticed that milk maids weren't catching and dying from small pox like everyone else, because they had been exposed to cowpox. This premise was used to create the first vaccine.
Vaccines give you immunity by injecting you with a small amount of a (usually inactive) pathogen. inside your body. This means your immune system produces antibodies against it. Similar to what happened with the milkmaids.
<h2>Phenotype probability</h2>
Explanation:
- In the given question,let say A is dominant allele and a is recessive allele
- Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by Aa
- When a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%
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>

The main role of DNA in the cell is the long-term storage of information. This backbone carries four types of molecules called bases and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
