The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches of rain falls yearly. Rain forests belong to the tropical wet climate group.
Explanation:
- The temperature in a rain forest rarely gets higher than 93 °F or drops below 68 °F. The average humidity is between 77 and 88%, rainfall is often more than 100 inches a year. In monsoonal areas, there is a real dry season.
- Rainforests now cover less than 6% of Earth's land surface. Tropical rainforests produce 40% of Earth's oxygen.
- About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, is used as an anesthetic and to relax muscles during surgery. Quinineis used to treat malaria.
- There are four very distinct layers of trees in a tropical rain forest. They are the emergent, upper canopy, understory, and forest floor.
- The soil of the tropical rainforests is shallow, poor in nutrients and without soluble minerals. Years of rainfall have washed away the nutrients in the soil obtained from weathered rocks.
- The tropical rain forest can be found in three major geographical areas around the world.
-
Central America in the the Amazon river basin. Africa - Zaire basin, with a small area in West Africa. Indo-Malaysia - west coast of India, Assam, Southeast Asia, New Guinea and Queensland, Australia.
Answer:
The Session layer (Layer 5)
Explanation:
The OSI (Open Systems Interconnection) seven-layer model is a reference model that explains how devices (or applications) communicate over the network. The model consists basically of seven different layers which are;
i. Layer 1 or the physical layer
ii. Layer 2 or the data-link layer
iii. Layer 3 or the network layer
iv. Layer 4 or the transport layer
v. Layer 5 or the Session layer
vi. Layer 6 or the presentation layer
vii. Layer 7 or the application layer.
Out of the seven layers, the session layer (layer 5) keeps track of a system's connections to send the right response to the right computer by setting up, coordinating and managing these connections. It controls, establishes and maintains the connection between multiple computers or applications on a computer.
