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.

HELPP!! Describe how the enzyme transforms the substrate. Include in your answer the vocabulary terms: substrate, active site, enzyme, product(s).
describe the arrangement of water molecules in a solid, liquid and gas form. how does the movement of the molecules differ in each form? Describe the bonds when the molecules are in motion.
Answer:
In a solid, the molecules are tightly packed in neat rows and they vibrate quickly. Solids have a definite shape and volume. In a liquid, the molecules have more energy and they move around more freely. Liquids have a definite volume but they don't have a definite shape. The molecules in gases are spread apart and move very freely with very much energy. Gases do not have a definite shape or volume.
Hope this helps!
:)
The description of the arrangement of water molecules and their motion in a solid, liquid and gas form and how they differ in each form is as follows:
Solid state is characterized because the molecules that compose it are very close together by a network of covalent bonds and in more or less fixed positions; this makes the distance between the particles practically unchanged.
This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.
In the liquid state, the forces between the particles are weaker than in the solid state, which allows the particles to have some freedom of rotation and translation, due to mobile ions.
Besides the vibration; they can slide over each other and maintain a constant mean distance between them without being fixed.
For this reason, liquids, unlike solids, take variable forms, depending on the container that contains them and they can also flow easily.
Their similarity to solids is based on the fact that, like the solids, they are difficult to compress and have constant volume.
In the gaseous state the attractive forces are practically zero and the particles acquire a total mobility of vibration, rotation and translation,
Being the distance between the molecules much greater than the one that they have in solid or liquid state and, in addition, variable at all times.
Gases, unlike solids and liquids, can be easily compressed or expanded and also take the shape of the container that contains them, occupying the entire available volume.
Therefore, the intensities of the interactions or cohesion forces of water molecules are not the same in solids, liquids and gases, the effects of movement and interaction on the arrangement of the particles are opposed, resulting in different states of aggregation.

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.

Most pneumonia infections are caused by a virus or bacteria. What characteristic could scientist use to distinguish an infection caused by bacteria from an infection caused by a virus? 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

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).

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.
