The way genes determine traits with cells is now well understood. This has opened up a new field of study called genetic engineering, through which organisms can be modified or engineered to possess new traits. It is common practice in the field of genetic engineering to remove a gene from one organism and insert it into the genome of another. It is a challenging task, but many examples of genetically modified organisms have been produced in both the plant and animal domains. Since genes from one organism can be inserted into the genome of a completely different organism, which statements below are conclusions that can be made from this observation? Select all that apply.

A. All forms of life have DNA in their nucleus.

B. In cells, traits are the result of proteins, and protein production is controlled by genes.

C. The molecular basis of inheritance is universal in all forms of life.

D. By changing one letter in the genetic code, the entire gene changes.

Can someone me with this and tell me what’s fracking and what does it have to do with carbon, carbon dioxide, or fossil fuels?

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.

Consider the model of the oxygen cycle on earth. the majority of earth's oxygen reservoirs are found in the a) atmosphere. b) biosphere. c) hydrosphere. d) lithosphere.
