Explanation:

Answer:

i would say B

Explanation:

that feels like the right answer

The center of the atom is called the nucleus. The correct option is B.

The nucleus is the central region of an atom that contains most of its mass.

It is composed of protons and neutrons, which are collectively known as nucleons.

Protons have a positive charge, while neutrons have no charge. Together, protons and neutrons form the nucleus and are responsible for the stability of the atom. Surrounding the nucleus are electrons, which have a negative charge and orbit the nucleus in various energy levels or electron shells. The nucleus is highly dense and compact compared to the electron cloud surrounding it.

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

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.

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.

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.

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.

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

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.
