Which process plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus?

Answers

Answer 1

Answer: The biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. The purpose in these cycles are to maintain balance and to ensure the ongoing process of the living and non-living organisms in the environment. These cycles’ help to living organisms survive and thrive. One popular example is the water cycle.

keeps the body warm

Answers

Answer: helps cool the body

removes waste chemicals through pores in the skin

Explanation:

Perspiration is a natural biological process that occurs in an mammals including human beings. Perspiration is required to maintain the homeostasis of the body. Homeostasis is the condition of maintenance of stable internal environment of the body with respect to the changes occurring in the external environment. Perspiration is also called as sweating when the body is exposed to heat it secrete sweat in order to provide coolness to the body. As the sweat contents are evaporated in the exposure of air. The sweat contents are emerge out by the pores present on the skin surface. The sweat consists of chemicals like aminoacids, salts and excess of water. Therefore, sweat removes the waste chemicals through the pores of the skin.

In the example of the finches on the Galapagos, what is the cause of the geographic isolation?A. the ocean
B. the foods the finches ate
C. the mating behavior of the birds
D. the climate on the different islands

Answers

The Galapagos Islands are geographically isolated due to the Ocean that surrounds the islands themselves. The finches can't fly far enough to make it past the vast ocean to other mainland so they are stuck on the island and must adapt to what the island provides for food in varying areas.

What is a limitation of using electron microscopes to view specimens? (2 points)

Answers

Answer:

The electron microscope uses electrons to form images for this reason does not allow to observe living cells because they need to work in a high vacuum atmosphere, the samples require preparation through a long fixation process, which means that it is not possible to observe living cells. To observe a cell with this microscope, dead cells must be observed, after being fixed and stained with heavy metal ions.

In these microscopes it is not possible to observe the cells carrying out their normal behaviors (for example, migrating or dividing) under the microscope

The correct answer is C. You cannot view live specimens because the necessary preparation kills cells.

The answer is pretty self-explanatory. Unlike it, regular microscopes can view living creatures such as bacteria or similar.

How does mass extinction affect species that survive?There are no surviving species if a mass extinction occurs.

They will soon become extinct.

They combine gene pools.

They fill new roles in the changed environment.

Answers

When there is a mass extinction, species that survive will combine gene pools. A gene pool is the sum of population of same species have the same genetic material. Those species that survived will combine for them to survive from extinction. If there is a combination of gene pool then there will be a possibility that evolution will happen

The mass extinction may cause the arrival of new species in the new and changing environment.

Further Explanation:

Mass extinction is the phenomenon when there is the extinction of many organisms or the group of an organism from the Earth due to change in environmental condition as it would not allow the survival of these organisms in the new environmental condition. This may cause the appearance of a new organism or the spread of mutant organisms in the prevailing environment that may play new roles. Hence new kind of ecosystem may be formed in the changing environment and those organisms that survive or get adapted to this condition may reproduce more and increase in number.

Therefore mass extinction although causes removal of some organism but may provide a new platform for the arrival of new kind of species and formation of a new ecosystem.

Which can be concluded from a comparison of the two phylogenetic trees?A. Phylogenetic trees are not subject to change.
B. Classification can change with new discoveries and evidence.
C. Classification does not change with more evidence.
D. Phylogenetic trees are inaccurate.

Answers

Answer;

B. Classification can change with new discoveries and evidence.

Explanation;

-Classifying organisms on the basis of descent from a common ancestor is called phylogenetic classification

-A phylogenetic tree is a visual representation of the relationship between different organisms, showing the path through evolutionary time from a common ancestor to different descendants. Trees can represent relationships ranging from the entire history of life on earth, down to individuals in a population.

B because it shows how related species are so if they find new evedince showing 2 species are more related than we thought then the tree must change to show accurat information.
