The particles of a liquid are able to move around each other. What property of a liquid does this behavior create?
Answer:
Behaviour is in the form of surface tension.
Explanation:
The particles of the liquid are quite close to each other and move with the random movement around the containers. These particles tend to move rapidly in all directions due to the shorter distances between particles. The property of the liquids to flow is their viscosity. Described as the quality of the liquid to flow. They have no fixed shape, as they are made by tiny vibrating particles that are held together by intermolecular bonds. liquids don't disperse like the gases they have surface tension.Which of the following is an example of a parasite?

Answer:
Carbon=about 85.13%
Hydrogen=about 14.26%
Explanation:
Percent composition= (molar mass of element x amount of it)/Molar mass x100
C= 12x3/42.08 x100=about 85.13
H=6x1/42.08 =about 14.26

What caused the deer population to grow early on?
A.) An abnormally cold winter caused offspring to die.
B.) A drought caused there to be less food and water available to the deer.
C.)The number of births was equal to the number of deaths in the deer population.
D.) The deer had a better food source so they had 2-3 fawns per year instead of 1 fawn
per year.
Answer:
i think it is C but not 100% sure.
Explanation:
Answer:
D) The deer had a better food source so they had 2-3 fawns per year instead of 1 fawn per year.
The other options show that the populations actually decreased, due to cold temperatures and droughts.

Provide a brief description of how the respiratory system works
Answer:
The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.

Identifying Variables in the Effect of Type of Material on
Absorption Experiment
Answer the questions using the drop-down menus.
Which is the independent variable in this experiment?
Which is the dependent variable in this experiment?
Which is a controlled variable in this experiment?
In Absorption Experiment,
Water location is the independent variable in this experiment.
Room Temperature in the material is dependent variable in this experiment.
Type of a material is a controlled variable in this experiment.
What is Absorption Experiment ?Absorption experiment is nothing but the experiment of absorption of water in a material (sponge).
Experiment requires vessel, water and sponge.
Processor - take a vessel, pour water into it and dip sponge. take out the sponge. After taking of out sponge, water appears to be decreased from the vessel and sponge gets heavier. When we squeeze the the sponge, water drops down. It is because of water is absorbed by the spouge.
There are number of pores in the sponge, which absorbs the water.
Water location is the independent variable.
In this experiment Room Temperature is dependent variable in this experiment rate of absorption increases with increase in the temperature. decrease in the temperature cause to solidify the water. Type of a material is a controlled variable, we can change type of the material.

What causes adaptions to occur ?
Factors that influence general adaptation syndrome include that of a person’s health, nutrition, sex, ages, race, socioeconomic status, and genetics. These are factors that are either can precipitate a different reaction, while others are modifiable and unmodifiable traits.
In biology, adaptation has 3 related meanings. Firstly, it is the dynamic evolutionary process that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each organism, that is maintained and has evolved through natural selection. Historically, adaptation has been described from the time of the ancient Greek philosophers such as Empedocles and Aristotle. In 18th and 19th century natural theology, adaptation was taken as evidence for the existence of a deity. Charles Darwin proposed instead that it was explained by natural selection. Adaptation is related to biological fitness, which governs the rate of evolution as measured by a change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects. In mimicry, species evolve to resemble other species; in Müllerian mimicry, this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defenses in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight. Adaptation is a major topic in the philosophy of biology, as it concerns function and purpose (teleology). Some biologists try to avoid terms that imply purpose in adaptation, not least because it suggests a deity's intentions, but others note that adaptation is necessarily purposeful.

Answer: 6. The pressure inside the baloon will be 6.8 atm
7. The final volume is 21.5L at tempearture of 388 K.
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
[tex]P\propto \frac{1}{V}[/tex] (At constant temperature and number of moles)
[tex]P_1V_1=P_2V_2[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 3.5 atm
= final pressure of gas = ?
= initial volume of gas = 32 L
[tex]V_2[/tex] = final volume of gas = 19.3 L
[tex]3.5\times 32=P_2\times 19.3[/tex]
[tex]P_2=5.8atm[/tex]
Therefore, the pressure inside the baloon will be 5.8 atm
7. To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
where,
[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.
[tex]V_2\text{ and }T_2[/tex] are the final volume and temperature of the gas.
We are given:
[tex]V_1=13L\\T_1=235K\\V_2=?\\T_2=388K[/tex]
Putting values in above equation, we get:
[tex]\frac{13L}{235K}=\frac{V_2}{388K}\\\\V_2=21.5L[/tex]
Thus it will occupy 21.5L at tempearture of 388 K.
What is a chemical equation, and
how do scientists use these
equations to represent chemical
reactions?
Answer:
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.
In mathematic equations we use an equal sign (=) for example 2 + 2 = 4, but in scientific chemical equations, we use an arrow (→), for example C + O2→ CO2. To the left of the arrow, we have the 'before' situation. This side represents the substances we have beforethe reaction takes place. They are called the reactants.
