Which is a negative effect of deforestation on the environment?
habitat restoration
desertification
soil production
urbanization
The negative effect of Deforestation on the environment includes biodiversity loss, soil erosion, water pollution, and desertification. So option B is correct.
What is meant by deforestation?Deforestation is the process of removing trees from a forest to facilitate human activities. Deforestation is a major environmental issue as it can lead to biodiversity loss, habitat destruction, water pollution, and soil erosion.
The most common definition of deforestation is the felling of trees by humans. However, deforestation can also be caused by natural events such as floods or fires. Deforestation is most commonly used to clear land for agricultural purposes or to harvest timber from fallen trees.
The rapid decimation of forests is causing a biodiversity crisis unprecedented in history. The primary impact of deforestation on wildlife is habitat destruction. Many factors associated with the destruction of trees contribute to the extinction of species. Land erosion removes nutrients from the soil, which is a major source of food for animals and plants.

Assuming there has been no geological activity to disturb the order of the rock layers, rock layer is (b) The oldest rocks at Location.
What are the Finding of the oldest rocks?The global is a tougher challenge than it'd seem. Earth's crust is a dynamic gadget and is constantly in motion, so rocks are always being moved around, created and melted down withinside the fantastic geological recycling programThe oldest zircon dates are 4.36 billion years. Before this study, the oldest dated rocks have been from a frame of rock called the Acasta Gneiss withinside the Northwest Territories, which can be 4.03 billion years old.

What is the branch of biology that investigates cells called?.
Answer:
The branch of biology that studies the cell and its process in detail is called cellular biology or cytology
Explanation:
This includes studying their structure, functions, and biochemical processes.
The branch of biology that investigates cells is called cell biology.
What is cell?Cell is the smallest unit in biology that can sustain life on its own and makes up all living things as well as the body's tissues.
The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The substances that enter and leave the cell are governed by the cell membrane, which encloses the cell.
The study of cell structure and function is known as cell biology, and it is based on the idea that a cell is the basic building block of all life.
A thorough grasp of the tissues and organisms that cells make up is made possible by concentrating on the cell.
Thus, cell biology is the branch that investigates cells and its structure and functioning.

If you were to observe the activity of methylated dna, you would expect it to _____.
If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
What is the activity of methylated DNA?DNA methylation is a process by which methyl is added to the DNA molecule which can change the activity of a DNA without changing the sequence. When it is located in a gene promoter, DNA methylation acts to repress gene transcription.
So we can conclude that If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.

Which is a tectonic process that forces rock up from beneath earth's surface
Answer:
Uplift is a tectonic process that forces rock up from beneath earth's surface
Uplift is a tectonic process that forces rock up from beneath earth's surface.
What is tectonic process?
The process of plate tectonics may be driven by convection in Earth's mantle, the pull of heavy old pieces of crust into the mantle, or some combination of both.
Uplift, in geology, vertical elevation of the Earth's surface in response to natural causes. Broad, relatively slow and gentle uplift is termed warping, or epeirogeny, in contrast to the more concentrated and severe orogeny, the uplift associated with earthquakes and mountain building.
