How Clark Developed Seizures
The following list is not in the correct order. The first three events are numbered correctly. Drag and drop the
remaining events in the order that led to Clark's seizures.
picture above for the order.
Answer:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures
Explanation:
Seizures are defined as the common complication of drug intoxication.
As per the clinical observations for Clark , normal blood and matrix sodium concentration lose sodium ions due to diarrhea. As given too much water causes sodium levels to decrease. Due to lower sodium concentration, the free water move into the matrix and increased matrix pressure. This pressure causes the abnormal neuron firing rate to increase which causes seizures.
Hence, the correct order is:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures

S-waves do not travel through Earth's mantle.______ 8. Surface waves are the first to arrive at a seismic station.______ 9. P-waves are bent when they strike the core.______ 10. On seismograms, seismic waves recorded from more distant facilities are closer together than those recorded from facilities close to the epicenter.______ 11. S-waves do not enter the core because they cannot travel through solids.______ 12. Seismologists have reasoned that Earth's outer core must be liquid based on the disappearance of S-waves.______ 13. Studies of how waves reflect deep inside Earth show that Earth's inner core is solid.______ 14. The P-wave shadow zone does not receive direct P-waves.
Answer 1:
Seismic waves change speed and direction when they encounter different materials: True
Explanation:
When a rock suddenly breaks withing the earth or there is an explosion, it releases vibrations that flow across the earth as waves. These waves are called Seismic waves. The change in speed and direction of the waves as they encounter different materials is called refraction.
Answer 2:
P-waves travel through Earth's mantle: True
Explanation:
Another name for a P-wave is Primary Wave. They are a type of seismic wave and are known to be faster in the speed of travel than other types of seismic waves. They travel through the earth's mantle in compressional and extensional forms. They have the ability to alter the volume of rocks through which they travel.
Answer 3:
S-waves do not travel through Earth's mantle: False
Explanation:
Also known as secondary waves, or shear waves, S-waves can travel through the objects. They occur after an earthquake and have the ability to forcefully dislocate or shake in a back and forth manner, the land that is perpendicular to its direction of travel.
Answer 4
Surface waves are the first to arrive at a seismic station: False
Explanation:
The first wave to arrive at a Seismographic station (which is an observatory for recording, and processing shockwaves, oscillations of the earth generated by earthquakes and other deep earth movements) is the Primary Wave or P-Wave.
Answer 5:
P-waves are bent when they strike the core: True
Explanation
The core of the earth comprises predominantly of Iron and Nickel. Because of the strength and structure of the core, the P-waves can still pass through but have their speed slowed very significantly and refracted.
Answer 6:
On seismograms, seismic waves recorded from more distant facilities are closer together than those recorded from facilities close to the epicenter.: False
Explanation
On seismograms, seismic waves recorded from more distant facilities are father than those recorded from facilities close to the epicenter.
P-waves are known to be faster than S-waves. The difference between the speed in both waves are known constants. Thus the farther the distance of the waves from the point of an earthquake or epicenter, the farther apart they are.
Answer 7:
S-waves do not enter the core because they cannot travel through solids: False
Answer 8:
Seismologists have reasoned that Earth's outer core must be liquid based on the disappearance of S-waves. True
Answer 9:
Studies of how waves reflect deep inside Earth show that Earth's inner core is solid. True
Answer 10:
The P-wave shadow zone does not receive direct P-waves: True
The following statements shows if they are true or false properties of the S and P waves
5. Seismic waves change speed and direction when they encounter different materials is a True statement
6. P-waves travel through Earth's mantle is a True statement
7.S-waves do not travel through Earth's mantle is a False statement
8. Surface waves are the first to arrive at a seismic station is a True statement.
9.P-waves are bent when they strike the core is a true statement
10. On seismograms, seismic waves recorded from more distant facilities are closer together than those recorded from facilities close to the epicenter is a False statement
11.S-waves do not enter the core because they cannot travel through solids is a False statement
12.Seismologists have reasoned that Earth's outer core must be liquid based on the disappearance of S-waves is a True statement
13.Studies of how waves reflect deep inside Earth show that Earth's inner core is solid is a True statement
14.The P-wave shadow zone does not receive direct P-waves is a True statement

Southern Florida has many tropical hardwood hammocks—forest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.
Answer:
Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.
Explanation:
The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.

What allows the three atoms in a water molecule to stay together
Answer:
Three types of bonds hold atoms together within molecules: ionic, covalent, and polar covalent. ... Hydrogen bonds allow two molecules to link together temporarily. • Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds.
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Thus, option A is correct.
What are covalent bonds?A covalent bond is the exchange of electrons between atoms. This type of bond occurs between two atoms of the same element or elements that are close to each other in the periodic table.
Strong linkages—called covalent bonds—hold together the hydrogen and oxygen atoms of individual H₂O molecules.
Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge.
Therefore, covalent bonds formed by shared electrons of hydrogen and oxygen atoms of individual H₂O molecules. Thus, covalent bond allows the three atoms in a water molecule to stay together. Thus, option A is correct.

When completing fruit fly crosses, what is counted at the end of the cross?
A.parent flies only
B.offspring and parent flies together
C.offspring flies only
Answer:
A complete fruit fly crossing requires that at the end of the crossing only offspring flies be counted
Explanation:
The fruit fly —Drosophila melanogaster— was one of the species used by Mendel to carry out his experiences related to genetics. Its rapid reproduction allowed the observation of hereditary characteristics —such as eye color and wing size— in the offspring.
Any experiment in genetics involving the crossing of fruit flies must ultimately take into account the offspring flies, their characteristics and phenotypic proportions.
Regarding the other options:
The characteristics and number of the parent flies are data already known before the crossing of fruit flies, so they do not represent a relevant data to be taken into account at the end of the crossing.

Answer:
Form hypothesis: Where do you think trees get the nutrients they need to grow?
I think the trees get the nutrients from the soil and sunlight
Predict: Based on your hypothesis, how will the tree population change if ALL other organisms (deer, bears, and mushrooms) are removed from the forest?
I think they will increase dramatically because there is nothing affecting them badly.
Analyze: Remove ALL organisms except trees. Click Advance year a few times and select the DATA tab. Was your prediction correct? Explain what you found.
Yes my hypothesis was correct without the other organisms affecting the trees growth the tree population increased.
Draw conclusions: Substances that contain carbon and are produced by living things are called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.
Do your results show you that trees are producers or consumers? Explain.
Trees are producers because they make it by using the sun's light.
Analyze: Click the FOREST tab. Click the plus (+) button for mushrooms several times. Click Advance year a few times. Select the DATA tab. How did adding mushrooms affect trees?
adding the mushrooms didn’t affect the trees.
Extend: The mushrooms thrived without hurting trees. How could this happen? Try for two possible explanations. Write your ideas in the space below.
The mushrooms are decomposers; they thrive off of dead things including the trees so they do not harm the trees at all.
Explanation:
The trees in the forest controls the flow of water on the land.
When heavy rainfall occurs the trees help in trapping the water in the soil which reduces the chances of flood. These trees also provide habitat as well as food for living organisms that lives in the forests.
The trees get the nutrients they need to grow from the soil with the help of their roots. Decomposers present in the soil feed on dead bodies which turn into nitrogenous substances that is used by the trees for making amino acids.
The tree population increases if all other organisms such deer, bears, and mushrooms are removed from the forest because these organisms feed on the trees so increase occur in the tree population.

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.
What type of landscape made up most of the land during the Carboniferous period
Answer:
Characteristic of the Carboniferous period (from about 360 million to 300 million years ago) were its dense and swampy forests, which gave rise to large deposits of peat. Over the eons the peat transformed into rich coal stores in Western Europe and North America. The name "Carboniferous" refers to this coal.
