In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer or soap and warm water for two minutes; then they dried their hands with a paper towel. The standard of comparison was rubbing hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. The sanitizer advertisement claimed to kill bacteria more effectively than any soap. After washing, hands were swabbed and then the swab applied to a culture plate and incubated. Finally, the bacterial cultures were counted. Students using the antibacterial santizer had the lowest bacterial culture count. What is the control in the experiment? A) washing with soap B) rubbing vigorously C) the time: two minutes D) rubbing hands in warm water
Oceans and seas can act as a heat reservoir to regulate climates. They can both absorb great quantities of heat in the summerRead theOceans and seas can actas a heat reservoir to regulate climates. They can absorb great quantities of heat in the summer, with very little temperature change. In the winter, oceans and seas release the heat. This is the main reason why coastal climates are milder compared to inland climates. Which choice correctly explains this phenomenon? 1) the high boiling point of water caused by hydrogen bonding 2) the high specific heat of water caused by hydrogen bonding 3) the high heat of vaporization of water caused by the non polar bonds 4) the high freezing point of water caused by the strength of its covalent bonds

This trochophore larvae is planctonic which means it is a free-swimming.

hybridization
DNA profiling
cloning

Answers

The correct answer would be DNA Profiling. When Joe denied being the father of Lisa, Lisa's mom took Joe to the court to prove that he was Lisa's biological father. One way of proving that he's truly the biological father is by undergoing both DNA's into DNA profiling.
