Define these words:

6. cultivar-
7. inbreeding depression (include how to prevent it)-
8.seedbank (include reasons for having them)-
9. gene promoter-
10. genetic trespass-

6. cultivar- a plant variety that has been produced in cultivation by selective breeding
▁▁▁▁▁▁▁▁▁▁▁▁

7. inbreeding depression (include how to prevent it)- is the reduced biological fitness in a given population as a result of inbreeding, or breeding of related individuals.

The first step in managing a hatchery population to prevent inbreeding depression is to decide what level of inbreeding causes problems. Unfortunately, there is no answer to this seemingly simple question.
▁▁▁▁▁▁▁▁▁▁▁▁
8.seedbank (include reasons for having them)- A seed bank (also seedbank or seeds bank) stores seeds to preserve genetic diversity

Aside from crop diversity, there are many other reasons we need to store and preserve seeds:

Climate change: Scientists are concerned that climate change will cause extreme weather conditions and bring new pests into some environments. These events could cause certain species of plants to go extinct [source: Rosenthal].

Natural disasters: Natural disasters can wreak havoc on a region's ecosystem. After the 2004 tsunami destroyed rice paddies in Malaysia and Sri Lanka, international seed banks provided local farmers with varieties of rice to begin growing their crops again.

Disease: Disease quickly and easily wipes out crops. For example, a recent strain of the disease called stem rust may have the capability to infect up to 25 percent of the world's wheat supply.

Man-made disaster: Man-made disasters can be as devastating to plant life as natural disasters. An obvious example would be war. In fact, one of Iraq's vital seed banks was looted during fighting].Research: Indigenous people have used plants to cure sickness for centuries. One in every six wild plants is used for medicinal purposes. Who knows what diseases the right plant or herb could eradicate?
▁▁▁▁▁▁▁▁▁▁▁▁

9. gene promoter-  is a region of DNA that initiates transcription of a particular gene.
▁▁▁▁▁▁▁▁▁▁▁▁
10. genetic trespass-  is a technique to splice, 
delete, add, isolate, recombine or transfer genes from one 
organism to another that may be totally unrelated.

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. earth science (also known as geoscience), is an inclusive term for all sciences related to earth (geology, meteorology, oceanogr maphy, etc).  although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.    environmental and earth science study the interactions of four major systems or “spheres” (figure 8.6).  the  geosphere  consists of the core, mantle and crust of the earth.the  atmosphere  contains all of the earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.the  hydrosphere  contains all of the solid, liquid and gaseous water on earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found.  ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields.  the  biosphere  is the collection of all earth’s life forms, distributed in major life zones known as biomes:   tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.although the four systems have their unique identities, there is substantial interaction between them.  environmental scientists study the effects of events in one sphere on the other spheres. for example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows: example 1 (volcano)    on may 18, 1980, mount saint helens, in the state of washington, erupted.  this event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere.  such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. the following are but a few of the myriad of interactions resulting from a volcanic
