<h2>Kelp forests decline</h2>
Explanation:
- Kelp forests rely on the proper balance of herbivory and predation
- Sea urchins dwell on the seafloor where they forage on macro algae, including giant kelp,if their populations are left unchecked by predation they can prevent kelp from growing which can transform a thriving community of kelp into an oceanic desert, known as an urchin barren
- If there is a decline in sea urchin population then there will be an increase of kelp population because it lost a predator
- The kelp crab will diminish because the sea otters would prey on them more often after losing a food source and the sea otters population will also decrease with time
- The horn sharks will slowly die from the lack of food because sea urchins were their only prey and the northern elephant seals will decline as well because of the death of horn sharks
- Hence, the decline in sea urchin population will upset the entire kelp population
Explanation:
Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.
Although the direst consequences of human population growth have not yet been realized, exponential growth cannot continue indefinitely.
In the late 1970s, China’s “one-child” policy tried to control population growth, but restrictions were relaxed in the early 2000s.
Answer:
These embryonic stem cells are known as pluripotent stem cells. ... When a cell undergoes mitosis, it duplicates its DNA and separates into two new cells that have the same genetic code. They are two identical copies (or daughter cells) from one mother cell.

In pneumonia, the accumulation of pus and/or fluid will thicken the respiratory membrane and slow down the diffusion rate. This would decrease the amount of oxygen taken up by the blood.
<h3>How does pneumonia affect diffusion in the alveoli?</h3>
Pneumonia is caused by an infection, and a wide variety of microbes can infect the lungs. Pneumonia is typically brought on by bacteria or viruses, but it can also be brought on by fungus and other organisms. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing.
In alveoli, blood is given oxygen and carbon dioxide is expelled. Pneumonia causes the alveoli in one or both lungs to swell with fluid and pus (exudate), obstructing normal gas exchange. Consolidation and collapse of the lung is another name for this. Diffusion is the method used for gaseous exchange at the alveoli.
