Answer:
A. Selective breeding
Explanation:
Imagine your at school or where ever you wanna be and you see a girl/boy that you really like because of their lips or how great their hair looks or the size of their eyes or what ever else. ( Sorry for some of those very visual images there... ) That's called selective breeding.
Fats and lipids are hydrophobic which makes them water repelling compounds. Therefore, presence of a waxy coating on the outer skin of the desert plant prevents loss of water via evaporation from the skin of the plants. This helps the plant store water and increases its survival period.
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.
