The tools used by marine scientists to make observations about oceans and marine organisms are Remote Operated vehicle (ROV), Automated untethered Vehicle (AUVs), Global positioning system (GPS) and Human-occupied vehicle (HOV).
<h2>Further Explanation
</h2>
ROV mean Remote operated vehicle which allows marine scientists to explore the ocean without necessary being in the ocean. Remote Operated Vehicle is a robot that is controlled by a person on the ship.
It is connected to the ship and the person that controls it uses joystick, which is similar to how we play a video game. It has a still camera, video camera and lights used to transmit videos and images back to the ship.
Automated untethered vehicles (AUVs) are untethered, unmanned vehicles that are used by marine scientists to conduct underwater research. Through Micromodem, an operator controlled computer passes information or command to AUVs in regards to when, where and what they sample. AUVs use different types of equipment for surveying and sampling such as sonar, camera and depth sensors.
Global positioning system (GPS) receiver is a navigation system that is used to show the location of the ship. GPS provides accurate navigation information for marine scientists.
Human occupied vehicle (HOV) also known as manned submersibles have the capacity to reach the full-depth of the ocean. It is used by marine scientists to carry out geophysical, geochemical, and biological studies, viewing and sampling of organism.
It has high quality video imaging system and can produce 3-D movies. It also has sophisticated syntactic foam.

The scientist that thought he had proven that plants obtain their nutrients from water rather than soil is Van Helmont.
No generations or hybrid would form before meselson and stahl would have observed evidence of a band in the cscl gradient.
The conservative model predicts that, following a single replication, half of the newly formed DNA double helices will be made entirely of the original, or old, DNA, and the other half will be entirely new. Then, each double helix would be completely replicated during the second round of replication. After that, 25% of the double helices would be all new, and 25% would be entirely old. Thus, the fraction of entirely new DNA double helices would increase with each succeeding round of replication, but the total number of completely unique DNA double helices would remain constant. Therefore, no hybrid DNA molecule containing 14N and 15N is replicated in the conservative model.
