The above diagram illustrates how nature recycles what natural resources?
The diagram illustrates how nature recycles carbon through the various spheres of the globe.
Carbon cycleThe diagram illustrates the cycling of carbon.
Carbon is an important element in nature and cycles through various spheres of the globe.
One of the reservoirs of carbon is the atmosphere - it exists as carbon dioxide. The supply in the atmosphere is maintained by burning, respiration and decay of living organisms, volcanic eruption etc.
Carbon is fixed into living organisms (the biosphere) via photosynthesis.

Lifeforms have changed throughout Earth's geologic history. Scientists learn about these changes by studying the fossil record. For example, scientists have learned when different groups of organisms first appeared. These events can be placed within specific periods on the geologic time scale, which is shown below.
Fishes with jaws first appeared during the Silurian period, and dinosaurs first appeared during the Triassic period. Large mammals first appeared after both dinosaurs and fishes with jaws.
Using this information and the geologic time scale above, choose the period in which large mammals first appeared.
A.
Permian
B.
Ordovician
C.
Tertiary
D.
Cambrian
Answer:
C. Tertiary
Explanation:
mammals have fur unlike the others period animals
Tertiary is the period in which large mammals first appeared.
What is Tertiary period?The Cenozoic era's initial geological phase is the tertiary, which is also known as the Paleogene and Neogene periods. Between 66 million and 2.6 million years ago, there was a geological epoch called the Tertiary.
The Cretaceous-Paleogene extinction catastrophe at the beginning of the Cenozoic Era marked the start of the Tertiary Geological Period, which lasted until the Quaternary Glaciation at the end of the Pliocene Epoch.
The tertiary period began approximately 66 million years ago with the extinction of the dinosaurs, and it ended when the Quaternary Period's ice ages started, or roughly 2.6 million years ago.
Therefore, Tertiary is the period in which large mammals first appeared.

Which process helps replace damaged skin cells?
meiosis
mitosis
fertilization
fusion
Answer:
1) growth and development
2) to heal wounds,cuts,etc.and replace damage cells
3) to maintain the ideal surface area to volume ratio
❕♥️HOPE IT HELP'S♥️❕Mitosis is a process of cell division that results in the formation of two new daughter cells. It plays a crucial role in living organisms. It helps to maintain the genetic stability and helps in increasing number of cells in body thus leading to growth.
Replacement of damaged cells is carried out by mitosis. Mitosis helps in the production of identical copies of the cells this helps in repairing the damages tissue or worn out cells. It creates new skin cells to replace read skin cells.How can cells from the same organism have such different shapes and functions?
Answer:
As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity. B Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
Explanation:
Answer:
Because cells are not only characterized by by their genetic material and other interior components, but also by the genes they express. Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. For example melanocytes in the skin are highly specialized cells which mostly make the pigment melanin. Plasma cells on the other are highly specialised for making antibodies.
