Explain how human activities can intensify, or even cause a landslide

Biology
2 answers:
defon3 years ago
8 0

Answer: There are various means by which the environment can be affected. These can be human activities or natural calamities.

Landslide is one of the major disaster which can be intensified by human activities.

Mining, deforestation, construction are some of the activities that can loosen the soil which aids to intensify the landslide.

Once the landslide is occurring the loosen soil intensifies the landslide. So, the activities that loosens the soil must be avoided to prevent landslide frequently.

The human activities directly or indirectly affect the nature. The deforestation and the removal of the vegetation  for the purpose of development or timber, the land is exposed to the dangers of the landslide. The tress, plants and other vegetation keeps the soil in place with the help of their roots. The soil erosion is prevented by the trees, but the cutting down of them by the humans increases erosion and hence, the risk of landslide.

How could human activity alter the availability of water in an ecosystem.
Sonja [21]

Answer:

Many activities of human alter the availability of water in ecosystem.

Explanation:

We know that water is an essential item for daily use and development works. Water is required for different development processes.

Although, the drinking of water is foremost work, but human beings utilize water into agricultural practices, industries, cleaning activities etc. These activities of human beings alter the availability of water in an ecosystem. Thank you

Nitella [24]
The answer is 3. <span>made from the remains of living organisms.

Sedimentary rocks are formed at Earth's surface. They can be clastic, chemical, and organic.
Clastic sedimentary rocks are the result of sedimentation of rocks and mineral fragments. Chemical sedimentary rocks are the result of sedimentation of chemical solutions of dissolved minerals.
<em>Organic sedimentary rocks are made from the remains of living organisms, fossils and corals.</em>

Write a summary about the cell theory
julia-pushkina [17]

Answer:

Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:

all organisms are made up of one or more cells,

all the life functions of an organism occur within cells,

all cells come from preexisting cells.

Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:

all known living things are made up of one or more cells,

all living cells arise from pre-existing cells by division,

the cell is the fundamental unit of structure and function in all living organisms,

the activity of an organism depends on the total activity of independent cells,

energy flow (metabolism and biochemistry) occurs within cells,

cells contain hereditary information (DNA) which is passed from cell to cell during cell division,

all cells are basically the same in chemical composition in organisms of similar species.

The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

I believe it would be polyphyletic.
Polyphyletic groups are formed when two lineages convergently evolve similar character states. Organisms classified into the same polyphyletic group share phenetic homoplasies as opposed to homologies. The key difference between paraphyletic and polyphyletic groups is that paraphyletic contain their common ancestor, whereas polyphyletic groups do not.
