Lymph nodes. They comprise the lymphatic system that
connects to the blood circulatory
system. They are significant in the
immune system. At the lymph nodes, foreign bodies
in the lymph, such as pathogens, are filtered
and trapped in lymph nodes where they are later destroyed by lymphocytes.
All of the following is leading to less habitable land for human populations except fewer wildfires. A wildfire can burn a natural area.
A wildfire is a fire that can burn an entire natural area (e.g., forest, grassland, prairie, etc).
Wildfires are generally due to anthropogenic (human) unconscious activities, but they can also be natural (for example, wildfires caused by lightning).
It has been proposed that when considering the total surface area burned at the global Earth level, wildfires declined over the last decades.

1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
<span>Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.</span>
