Polar bears live in the north pole, and they rely heavily on the large slabs of ice for many aspects of their lives.
For example, they often hunt for animals in the ocean, and these chunks of ice serve as resting points for the bears when they tire of swimming.
If these ice blocks are melting, the polar bears will have to swim farther distances. Many become tired and don't make it, dying in the process. Therefore, the change in climate negatively affects polar bears.
The answer will be 1. Energy from photosynthesis will transfer to the snake.
When bacteriophage is used to infect bacterial cells in culture grown under unfavorable conditions, it will incorporate its genomic DNA into the bacterial genome.
Bacteriophage, also known as a phage, is a virus which infects and replicates within bacteria. Bacteriophages contain DNA or RNA genome which is encapsulated in a protein coat.
Bacteriophages infect the bacterial cultures. When they infect the bacteria, the genomic DNA of the bacteriophage enters into the bacterial genome. It then replicates within the bacteria. It hijacks its cellular machinery so that it can and does not allow it to produce bacterial components anymore and rather produce viral components.
