"The Hershey-Chase experiment was a series of experiments, conducted in 1952 by Alfred Hershey and Martha Chase. It identified DNA to be the genetic material of phages and, ultimately, of all organisms. Before this experiment was conducted, it was suspected that proteins were the genetic material in viruses, not DNA. A bacteriophage is a small virus that infects bacteria. It consists of a protein coat that encloses the genetic material. When a phage infects a bacterium, it inserts its genetic material into the bacterium, while its coat remains outside." ~https://br.answers.yahoo.com/question/index?qid=20080328174055AAMvFCw maybe this can help
Answer:
The balance form of the equation is given below.
Pb(NO3)2+2KI ——-> 2KNO3 + PbI2
Explanation:
In this equation lead nitrate and potassium iodide are reactants while potassium nitrate and lead iodide are the products. In the unbalanced form of equation, two molecule of iodine are formed in the product whereas there is only one molecule of iodine is present in the reactant. So for balancing this, 2 value is put in front of potassium iodide but by putting 2, potassium is also double in the reactant so 2 is also placed in front of potassium nitrate in the product and the equation is balanced.
Farmers and other people that deal with plants no longer have to use pesticides, and other insect repellants and killers.
Answer:
Enzymes
Explanation:
Enzymes are biological molecules that catalyze specific reactions.
Enzymes are organic proteins, and are catalysts for chemical reactions, meaning that they help to speed up the reaction.
They do this by lowering the amount of activation energy needed.
