Nuetrik [128]

Answer:

1. Biological structure of the human body

The human body is organized in different levels according to their complexity.

The levels are the folowing (increasing complexity).

1. Atom (N, O, C,..)

2. Molecule (Protein, lipids, water...)

3. Organelle (mitochondria, golgi apparatus,...)

4. Cell (blood cells, bone cell,..)

5. Tissue (connective tissue, epithelial tissue,..)

6. Organ (lungs, kidney,..)

7. Organ system (skeletal system, muscuar system,...)

8. Organism (the human body)

Each of the levels is formed by an agrupation of the previous level. For example, cells are formed by a number of organelles, and a group of cells form a tissue.

Cells are the basic units of structure of the body, and there are different types of them.

2. Homeostasis

Homeostasis is a process of the body by which the organism works to maintain a stable internal environment, while adjusting to changes in the external environment.

This process is possible because of the work of both the nervous system and the endocrine system. While the first controles the body's activities and detects the necesity of adjustments, the second regulates the activities by using hormones.

Which ecosystem has more biodiversity EXPLAIN!
Gekata [30.6K]
The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.

Hope this helps!
