A microbe from an ecosystem that exists in the same arctic region has infected the whale population. The graph below shows the new carrying capacity for the whale population. Explain how these microbes have affected the whale population. Does this new evidence change the seal and killer whale relationship? Does this new relationship represent a sigmoid or peak phenomenon? Please provide supporting details.

Decrease population.

Explanation:

These microbes decrease the whale population by causing infection that leads to the death of the whale. The seal and whale relationship is the relationship of prey and predator. In this relationship, seal is prey and whale is predator that feeds on seal. Whale is considered as the predator that is present at the top of the food chain which feeds on fish and squid, seals and sea birds etc.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.

b. the carbon cycle ensures living things have a source of hydrogen
