They looked and saw Rosalind Franklin's X-ray crystallography which sparked them to think about the double-helix structure, and from there, they played around with cafeteria items (forks and spoons and whatnot) to create a model that finally worked.
Answer:
Taking antibiotics only on doctor prescription and completing the full course of antibiotics.
Explanation:
Antibiotic resistance occurs when bacteria do not get harmed or killed by a drug which is made against them. Misuse and overuse of antibiotics are the main culprits which induce antibiotic resistance in bacteria.
To prevent the spreading of antibiotic-resistant bacteria antibiotics should only be taken on doctor's prescription. Full course of antibiotics should be done to eliminate all the bacteria which ensures that no bacteria is left to gain antibiotic resistance against the drug.
Antibiotics do not affect or kill virus therefore they should not be taken in viral infection.
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.
<h3>What is heterozygous?</h3>
The occurrence of different types of alleles is referred to as heterozygous condition.
A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.
The missing options of the question are:
- Yy ´ yy
- YY ´ yy
- Yy ´ Yy
- yy ´ yy
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.
Thus, the correct option is A.

Answer:
Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range.
