What are some possible consequences if transgenic salmon escape from their pens into the ocean population?
babunello [35]

Answer:

If the transgenic salmon escapes from their pens into the ocean population there are chances that they would compete with the wild salmons for food and space. They may also bring new diseases and changes to the food webs and ecosystem of the ocean.

Explanation:

A transgenic organism or genetically modified organism is the one that undergoes alternation through recombinant DNA technology.

No, I do not think that FDA should approve Aquabounty of growing and selling transgenic salmon since there is higher chance that they may interfere and disturb with the ecosystem and might also bring new diseases.

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.

Jlenok [28]

Answer:

This question lacks options, however, primary succession will be explained for detailed comprehension.

Explanation:

Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.

Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.
