A massive landslide Mud flows in the Toutle river.
How changes have occurred in the North Fork Toutle River?There had been many earthquakes in the area prior to eruption but this happen to be a massive land slide because a moving magma have over steepened the mountain slopes.
This geologic process uses gravity to cause rock, soil, artificial fill or a combination of the three to move down a slope. Slow weathering of rocks as well as soil eruption and volcanic activity also causes landslides
Thus, massive landslide Mud flows in the Toutle river.

Cyanobacteria are photosynthetic marine organisms. why would these organisms likely be found only in shallow ocean zones? the current in deeper ocean zones is too traumatic. the amount of oxygen in deeper ocean zones is too high. the amount of light in deeper ocean zones is too dim. the amount of pressure in deeper ocean zones is too low.
Cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.
What are cyanobacteria?Cyanobacteria are any of the very many photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae.
Cyanobacteria are photosynthetic organisms, hence, require sunlight energy to undergo the process.
Light from the sun can only reach the photic zone of a water body, hence, cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.

Answer:
The amount of light in deeper ocean zones is too dim.
Explanation:
Not: the amount of oxygen in deeper ocean zones is too high, because their is barely any oxygen in deep ocean. Not:
The current in deeper ocean zones is too traumatic, it is very still, no currents.
The amount of pressure in deeper ocean zones is too low, there is high pressure deep ocean, like for example, when you go deeper in water your ears get filled, like you can't hear because of the high pressure.
So the answer is; The amount of light in deeper ocean zones is too dim.

Any change in a sequence of DNA is ...
A. a mutation.
B. mitosis.
C. a virus.
Answer:
A. Mutation
Explanation:
A change in the sequence of DNA would be best classified as a mutation. Mitosis refers to the reproduction of cells, and a virus is a foreign body that infects cells.
Answer:
A. Mutation
Explanation:
when you change DNA it causes mutations because they have been ruptured and many things could go wrong in your body, so stay away from x-rays and such because that can cause one. :)
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.

Cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.
What do you mean by Cell theory?Cell theory may be defined as a theory given by M.J. Schleiden and T Schwann which states that all living organisms are made up of cells which are the smallest unit of all living entities.
It is only due to mutations, cell changes its identity and properties randomly. Hence, it seems very tough for scientists to analyze all the mutations in the cell.
Therefore, cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.

Why is hair follicle and hair shaft important ?
Answer:
A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.

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.
