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

During a science lab the teacher provided Michael with a triple-beam balance, a ruler, and four cube-shaped metals. Based on Michael's calculations and the table below, the conclusion can be BEST made Substances can be identified by their density
what is density?
Density refers to the mass of a unit volume of a material substance. The formula for density is represented by d = M/V, where d is density, M is mass, and V is volume.
It is commonly shown as units of grams per cubic centimeter, it can also be expressed as kilograms per cubic meter .
Density can used to define how different materials interact when mixed together. For example Wood floats in water because it has a lower density, while an anchor sinks because the metal has a higher density.
Density can be applied in pipe design, shipbuilding, helium balloons, weight distribution in the aero plane, and the fact that ice floats on water.

Roberto stepped onto the hot sand at the beach. Realizing it was hot, he quickly moved to the shaded area. Which two systems worked together to move him safely into the shade so that he doesn't hurt his feet? A. Nervous and muscular B, Nervous and cardiovascular C. Cardiovascular and respiratory D. Immune and muscular
Answer:
A. Nervous and muscular
Explanation:
The thermoreceptors of the sensory afferent pathway were activated when they perceived high temperatures, and after that they sent a signal to the CNS for it to execute the "withdrawal" reflex in the face of danger or pain.
The reflex act is an immediate and unconscious action, like walking, and like other movements that are coordinated between the CNS, SNP, NEUROMUSCULAR PLATE AND MUSCLE.

Why is the following molecule nonpolar and hydrophobic?
The image shows a polymer composed of a chain of 14 carbon atoms. The first carbon atom is bound to three hydrogen atoms. The next 12 carbon atoms are bound to two hydrogen atoms. The final carbon atom is bound to a carboxyl group.
The carbon and hydrogen atoms share electrons equally.
The glycerol molecule in fats contains a carboxyl group.
There are exactly three fatty acid chains present in each fat molecule.
There is an unequal distribution of hydrogen and oxygen atoms.
Answer:
a
Explanation:
The following molecule is nonpolar and hydrophobic because the carbon and hydrogen atoms share electrons equally. The correct option is A.
What are nonpolar and hydrophobic?Non-polar molecules are those which can not be dissolved in water. These molecules have ends that are not dissolved in water. Hydrophobic is a quality of the substance that is not dissolved in water or repels water.
The image shows a polymer made up of three hydrogen atoms are bonded to the initial carbon atom. Two hydrogen atoms are joined to the next 12 carbon atoms. A carboxyl group is attached to the last carbon atom.
Since charges fluctuate, a momentary dipole moment exists in a so-called nonpolar molecule.
Thus, the correct option is A, The carbon and hydrogen atoms share electrons equally.

Explain the role of the ozone layer in sustaining life on Earth.
Answer:
The O3 layer, (Ozone Layer) leads a greatly significant role in sustaining life on Earth. It acts as a barrier against the harmful UV rays from the Sun. The Ozone and Oxygen molecules are able to absorb a staggering 95% to 99.9% of the ultraviolet radiation travelling to our planet. When this ultraviolet radiation is absorbed, heat is generated.
Answer:
The ozone layer helps regulate the Earth’s temperature by absorbing a large percentage of the UV radiation entering the atmosphere. This protects living organisms from exposure to large amounts of UV radiation, maintains livable climates, and regulates the amount of harmful ground-level ozone.

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.

Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter
Answer:
c) The total amount of matter decreases over time.
Explanation:
The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).
The biosphere refers to the total of all ecosystems of the Earth.The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).
