Why is the intensity of a pulse different at different sites?
Answer:
Because pulse wave velocity decreases as arterial diameter decreases, a slight difference in local vasculature can cause inter-site differences not only in pulse transit time but also in its variations.

Group of answer choices The bacteria would grow by itself outside the person. The virus would have DNA. The bacteria would make another person sick. The virus would have proteins.
Answer:
The bacteria would grow by itself outside the person
Explanation:
The bacteria would grow by itself outside the person. - this is correct. Bacteria are independent organisms that do not need other cells to replicate. However, viruses require the cell's machinery to divide and cannot survive independently
The virus would have DNA. - Both bacteria and viruses have DNA (or the virus might have RNA)
The bacteria would make another person sick. - Both viruses and bacteria could make another person sick
The virus would have proteins - Both viruses and bacteria have proteins

How is cold front formation different from stationary front formation? Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass. Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses. Cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold air mass moves over a warm air mass. Stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when a warm air mass moves over a cold air mass.

Which type of information can scientists collect using a seismograph?
a) slight shifts in the inclination of a surface
b) pollution levels in the air after a volcanic eruption
c) vibrations occurring inside Earth
d) temperatures of molten rock inside Earth
Answer:
C
Explanation:
Vibrations occurring inside Earth
The type of information that scientists collect using a seismograph is vibrations occurring inside Earth. The correct option is c.
What is seismograph?A seismometer is a measuring device that detects ground noises and shaking caused by earthquakes, volcanic eruptions, and explosions.
Seismographs are typically made up of a seismograph, a timing device, and a recording device.
Seismographs are devices that record the movement of the ground during an earthquake. They are installed in the ground all over the world as part of a seismographic network.
To better understand seismic waves, scientists developed and used a device known as a seismometer. Seismometers now assist scientists in predicting earthquakes.
Scientists use seismographs to collect information about vibrations that occur within the Earth.
Thus, correct option is c.

9. If your cells were used to discover a cure for a disease do you think you should have first given consent for their use? Should you also receive something back if the research makes lots of money. Explain why.
Answer:
If my cells were used to discover a cure for a disease I don't think it would matter to give consent because I would have saved lots of people. I think I should earn just a little bit of money, because they are my cells, but I don't think I should earn a lot or most of it.
Answer:
Yes, you need to give consent because otherwise, they can not have any part of you without consent.
Explanation:
You should expect some money even if it is a small amount to come to you due to you being the one with the cure therefor the scientist or bioglist would have to study them and would go on to trials if they make a vaccine. Always, give consent if you deem it the right choice never by force.
The human body is composed of cells, organs, organ systems, and tissues. How are these organized?
A) Groups of cells form tissues.
B) Groups of organs form tissues.
C) Groups of organ systems form tissues.
D) Groups of tissues form organ systems.
PLZ HELP
Answer:
C) Groups of organ systems form tissues.
Explanation:
Explain how dysfunction at one level of organization impacts other levels and provide an example.
Answer:
Please find the explanation below
Explanation:
All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.
Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).
