Explain how seismic waves are used to determine composition, thickness and density of the interior of the Earth (write 2-3 sente

nces)
Biology
1 answer:
Alexus [3.1K]3 years ago
7 0

Explanation:

Seismic waves are elastic waves that are able to propagate within the subsurface.

The travel - time to depth expressed in form of velocity is used to determine the composition, thickness and density of the interior of the earth.

  • Different earth materials shows different behavior in response of seismic waves.
  • By checking the attributes of the waves as they go through the subsurface, we can predict some of the properties of the underlying beds.

Answer:

Cell structure: The cell structure comprises individual components with specific functions essential to carry out life's processes.

Eukaryotic: A eukaryotic cell contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum.

Prokaryote: any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes.

Cytoplasm: a thick solution that fills each cell and is enclosed by the cell membrane.

Organelle: specialized structures that perform various jobs inside cells

Tissue: a group of cells that have similar structure and that function together as a unit.

Organ: a collection of tissues that structurally form a functional unit specialized to perform a particular function.

What is the natural source of energy in Mars and how is created, fission of fusion?
Alexxandr [17]

Answer:

Fission and fusion are two processes that alter the nucleus of an atom. Nuclear fission provides the energy in nuclear power plants and fusion is the source of the sun's energy. The use of fission in power plants can help conserve fossil fuels.

Did you get the same blood pressure reading manually as you did with the use of probes? provide at least two reasons these value
Genrish500 [490]
Part I
NO, this is because of different judgement as to when pulse start/stops.
In addition, computers are more sensitive than probes, prob could be more accurate because it does not have human error, which manual method has. Other factors that affect the reading may include temperature, eating, body position among others. 

Part II
The causes of changes in blood pressure that might occur within a given day include; stress and level of activity. Eating a flux of nutrients like sodium could affect the blood pressure. Also different requirements from the body . Therefore, if one is lying down versus when one is standing up, it might take more energy standing up, such that when one is relaxing lying down, blood pressure will be lower due to the relaxation.

Part III
What is needed to be kept constant through out the experiment is; 
same person, same amount of time in between readings or for the readings, same pressure that is pumped at the beginning, same temperature.
It is important to keep all those factors constant because if not, the factors that are not iv's could change the data. keep the same person because data can change a lot based on who you use while retrieving the data.

Part IV
Prehypertension is the sign that one might have high blood pressure in the future. it is valuable to know if one is considered prehypertensive because one can implement proper changes to lifestyle in order to maintain a healthy blood pressure.  

Part V
An ACE inhibitor works by blocking the body from producing angiotensin II which causes blood vessels to become narrower, raising blood pressure. This stops the chemical, thus relaxing the blood vessels and also lowering the blood pressure.
