Answer:
The correct answer would be parts of atmosphere, hydrosphere, and lithosphere.
Biosphere refers to the area of the earth where life exists. It ranges from the deepest sea to the high mountain tops.
On planet earth, life can exist on land or soil (lithosphere), water (hydrosphere) and in the air (atmosphere).
Thus, biosphere overlaps all these spheres.
cell theory
chromosomal theory
The most accepted theory regarding the make-up of living things is the cell theory.
It was proposed by German scientists Theodor Schwan, Mathias Schleiden and Rudolf Virchow.
It states that;
1. All living organisms are made of cells.
2. The cell is the basic unit of life.
3. Cells arise from pre-existing cells.
in addition the modern version of the cell theory states:
4. Energy flow occurs within cells
5. Heredity information (DNA) is passed from cell to cell.
6. All cells have the same basic chemical composition.

Cell Theory
Explanation:
Answer:
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.
The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
Answer:
The block o time in the geological time scale are called:
Eon: The biggest ones
Eras: Which are the middle ones
Periods: Which are the smallest ones.
Explanation:
The geological time scale classifies the lapses of time in different gradients. It does it like that to optimize the retrieval of data and locate the objects and phenomenons of study to analyze them and conduct the research in an organized way. Eons are classified in Archean, Proterozoic, and Phanerozoic. Eras are classified in: Early archean, middle archean, late archean, Early proterozoic, Middle proterozoic, late proterozoic, Paleozoic, Mesozoic, Cenozoic. Periods are classified in Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian, Triassic, Jurassic, Cretaceous, Tertiary, Quaternary.
