Use the following experiment to answer questions #16-#20. The materials needed are an ice cube tray, water, a clear jar or glass, and food coloring (darker food colorings are better).
16) Mix the water and food coloring and pour it into the ice cube tray. Put the ice cube tray in the freezer till frozen. Once frozen, fill the clear glass with warm water. Add one colored ice cube to the glass. Observe what happens. What starts to happen?
17) Does the colored water sink or float?
18) Why does the colored water behave in this manner?
19) How does this experiment show heat transfer?
20) What is this process called?
Answer:
the water begins to sink to the bottom of the glass. The colored water behaves this way because of convection currents. As the warm air rises, a pattern of air movement is formed called a convection current. We can see this in air and in water. The process is convection current.
Explanation:
Convection is one of three main types of heat transfer. The other two being radiation and conduction. Convection is the transfer of heat by the movement of heated particles into an area of cooler particles. You can experience convection when you light a match. The air directly above the lit match is always hotter than the air around the match.
This difference in temperature around the match is caused by effect of heat on the density of air. Hot air is less dense than cool air and will rise leaving the cooler air below. As the warm air rises, a pattern of air movement is formed called a convection current. We can see these convection currents in air and in water.
Convection currents in the atmosphere affect our weather. The rising of warm air and falling of dense cool air causes our winds. When warm, moist air rises and mixes with cold air, the atmosphere becomes unstable. This causes thunderstorms.
The Gulf Stream off the eastern coast of the States is a convection current. It carries warm water from the tropics up the east coast north toward the cold arctic waters.
Heat affects the density of water as well. You can create your own convection current with water that will allow you to see the currents caused by the density difference of water at different temperatures.
The warm water will melt the ice cube, but the resulting water will be very cold. This cold, dense water will sink to the bottom of the glass. You can see this happening because the melted water from the ice cube will be whatever color you made your ice cube.
As the water warms, it will rise back to the top of the glass. The colored water will allow you to see the convection current in the glass.

The force that pulls falling objects toward earth is called
Answer:
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
A nerve impulse is an electrical charge running across a neuron. Explain why the simulation supports this explanation.
Answer:
Sudden reversal of the electrical charge across the membrane of resting neuron
Answer:
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

Fecal coliform is an indicator of what type of disease?
Answer:
Explanation:
Some waterborne pathogenic diseases include typhoid fever, viral and bacterial gastroenteritis and hepatitis A. The presence of fecal contamination is an indicator that a potential health risk exists for individuals exposed to this water.
Answer:
Thermotolerant coliform bacteria (commonly referred as fecal coliforms) are the group most frequently used as indicators of fecal pollution because they behave in a similar way to most pathogenic bacteria in the environment, and, during treatment, they are abundant and easy to determine.

Modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve
from them.
Aepycamelus don't share any evolutionar relationship with modern camels.
Aepycamelus are modern camels' closest extinct relatives.
Aepycamelus are modern camels' closest living descendants.
Answer:
A. Modern camels share an evolutionary relationship with Aepycamelus, but they didn’t directly evolve from them.
Explanation:
The phylogeny chart shows that modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve from them
What is a phylogeny chart?A phylogeny chart is a chart that shows the relatedness of organisms by charting structural relationships in order to determine their evolutionary origins.
From the phylogeny chart , modern camels, Camelus share an evolutionary relationship with Aepycamelus as they both originate From a common ancestor, Protylopus.
However, modern camels do not directly originate from Aepycamelus.
Therefore, it can be concluded that modern camels share an evolutionary relationship with Aepycamelus, but they didn't directly evolve from them.

if a woman who is a carrier for Fragilex syndrome (an X-linked disorder) has children with a man who does not have the disorder, what chance do their
daughters have of being carriers of Fraglese
None
50%
25%
100%
Answer:
Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.
Explanation:
Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.
In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).
Cross X x XY
Alleles X Y
[tex]X^{f}[/tex] [tex]X^{f}[/tex]X [tex]X^{f}[/tex]Y
X XX XY
The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.
