Answer:
Disease and Famine
Explanation:
If there is a disease that affects a type of plant, having other types of crops to rely on could save one from starvation. Also, only planting one crop in an area can change the pH and nitrogen levels in negative ways, so that eventually no plants can grow there. Not to mention the obvious balanced diet needed for a healthy body.

Further Explanation:
The hydropower dam uses water instead of coal to generate electricity. Since they are build on the water, they will be using that source as a way to generate electricity. This will cause the water levels to be lower in some areas along the river.
When building a dam, they will need to use property that is located on the river. Many people own homes along the river banks all over the world. The company who will be building the dam will usually buy out the property owners at a fair market price. This will mean that they will have to move and leave their homes. The homes are typically torn down to make way for the dam.
In some instances, the water bills for the people in the area may be raised also since so much water is being used by the hydropower dam.

Answer:
Transduction is a process by which DNA is transferred from one bacterium to another by the action of a virus. It is also used to designate the process by which exogenous DNA is introduced into a cell by a viral vector. This is a tool that molecular biologists usually use to introduce a foreign gene in a controlled way into the genome of a recipient cell.
Explanation:
When bacteriophages (viruses that infect bacteria) infect a bacterial cell, their normal mode of reproduction consists in capturing and using the machinery of replication, transcription, and translation of the recipient bacteria cell to produce large numbers of virons, or produce particles. viral, including viral DNA or RNA and protein coat.
Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear
Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.
