Scientists and nutritionists have long suspected that high-fructose corn syrup, used to

sweeten soft drinks, is one of the causes of childhood obesity. In a recent study, at the

University of Cincinnati, researchers found that mice that drank water with added

fructose ate less solid food, gained more weight, and put on 90% more body fat than

mice that drank only water. Scientists concluded that fructose may affect metabolism in

a way that favors fat storage.

What is the independent variable?

The mice that drank only water

The presence of fructose in their diet

The quantity of water provided

The weight gained by the mice

Answers

Answer:

The presence of fructose in their diet

Explanation:

The independent variable in an experiment is the type of variable which is changed at intervals in order to study if it has a direct effect on the dependent variable.

The dependent variable in the experiment is the amount of weight gained by the mice in each group and the control group is the mice who drank the water without the fructose added.

Christy won by about 30 cm Christy won by about 30 cm Molly won by about 25 cm Molly won by about 25 cm Christy won by about 12 cm Christy won by about 12 cm Molly won by about 10 cm

Answers

Answer: Christy won Molly by 12cm

Explanation:

Ist step

Molly's ;ong jump was 118.3cm

Christy long jump was 51.18inches

2nd Step

we change christy score to cm so we can compare

1 inch = 2.54cm.

therefore 51.18 inches = 51.18 x 2.54= 129.9972cm

Christy won molly by 129.9971cm-118.3cm=11.69 rounded to 12cm

Christy won Molly by 12cm

When exposed to very high temperatures, metals like iron can be turned into fluids that flow and can be poured into molds. What happens within the iron to allow it to flow?

A) The energy of the solid decreases, and the particles begin to collide with high frequency

B)The energy of the solid increases, and the particles begin to slide past each other

C)The solids collide at an increasing rate until reaching equilibrium energy

D)The particles vibrate about equilibrium in an effort to minimize energy

Answers

Answer: B) The energy of the solid increases, and the particles begin to slide past each other.

Explanation:

The energy of the solid matter is required to be increased so that molecules of the solid matter get separated from each other and an transition from solid matter to liquid matter occurs. The liquid components of the matter will slide past each other as they have obtain energy for fluidity. The liquid iron can be molded into any shape and the energy decreases considerably.

A 1.00-L flask is filled with 1.00 moles of H2 and 2.00 moles of I2. The value of the equilibrium constant for the reaction of hydrogen and iodine reacting to form hydrogen iodide is 50.5 under the given conditions. What are the equilibrium concentrations of H2 , I2 , and HI in moles/L? H2 (g) + I2 (g) ⇌ 2HI(g)

Answers

Answer:

[tex] C_{H_{2}} = 0.07 M [/tex]

[tex] C_{I_{2}} = 1.07 M [/tex]

[tex] C_{HI} = 1.86 M [/tex]

Explanation:

The reaction is:

H₂(g) + I₂(g) ⇄ 2HI(g)

Initially, we have the following concentrations of H₂ and I₂:

[tex] C_{H_{2}} = \frac{n}{V} = \frac{1 mol}{1.00 L} = 1 mol/L [/tex]

[tex] C_{I_{2}} = \frac{n}{V} = \frac{2 mol}{1.00 L} = 2 mol/L [/tex]

Then, in the equilibrium we have:

H₂(g) + I₂(g) ⇄ 2HI(g)

1-x       2-x         2x

[tex] Kc = \frac{[HI]^{2}}{[H_{2}][I_{2}]} = \frac{(2x)^{2}}{(1-x)(2-x)} [/tex]

[tex] 50.5*(1-x)(2-x) - (2x)^{2} = 0 [/tex]

By solving the above equation for x we have:

x₁ = 2.32 and x₂= 0.93

Hence, the concentrations of H₂, I₂ and HI are:

[tex] C_{H_{2}} = 1-x = 1 - 0.93 M = 0.07 M [/tex]

[tex] C_{I_{2}} = 2-x =  2 - 0.93 M = 1.07 M [/tex]

[tex] C_{HI} = 2*x = 2*0.93 M = 1.86 M [/tex]

An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.

What is an echolocation ?

Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.

(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.

Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.

Thus, option A is correct.

You have a solution of water and pure ethanol. The boiling point of water is 100 degrees Celsius and the boiling point of pure ethanol is 78 degrees Celsius. A. What process would you would use to separate this solution? Describe, in detail, how this process works.

Answers

Answer:

Distillation

Explanation:

A solution of water and ethanol are miscible. Hence, they can only be separated by a process known as distillation. Distillation is the process in which two or more constituents in a mixture are separated based on there difference in boiling points. The mixture is subjected to high heat and the one with the least boiling point distills/evaporates out first followed by the next least boiling point.

From the explanation above, it can be deduced that ethanol (with boiling point of 78°) will be distilled out while water remains in the boiling tube or container.

A piece of metal of mass 27 g at 93° C is placed

21°C. The final temperature of the mixture is 34.9 ° C. What is the specific heat capacity of the metal? Assume that there is no energy lost to the surroundings.
Answer in units of J/g. ° C

Answers

Answer:

1.586 J/g°C

Explanation:

So, we have the formula [tex]q = mc\Delta t[/tex].

Since heat released by the metal is = to the heat absorbed by the water (because they eventually become the same temperature in solution), we can say

[tex]m_{water}C_{water}(T_{water}-T_f) = - m_{metal}C_{metal}(T_{metal} - T_f)[/tex]

Plugging in, we get:

[tex]59.2*4.184*(21- 34.9) = - 27*C_{metal}*(93 - 34.9)[/tex]

Solving, we get [tex]C_{metal} = 1.586[/tex] J/g°C.

Gains energy by eating other living things

The statement 'gains energy by eating other living things' is a characteristic shared by both primary and secondary consumers (Option D).

Producers (e.g. algae and plants) are autotrophic organisms that generate their own food.

Primary consumers and secondary consumers are heterotrophs that need to eat other organisms to survive.

Primary consumers can be, for example, herbivores, whereas secondary consumers can be carnivores.

In conclusion, the statement 'gains energy by eating other living things' is a characteristic shared by both primary and secondary consumers (Option D).

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

of water to raise its temperature from 35 C
to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.

Answers

Q must be supplied = 119523.3~J

Further explanation  

The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released  

Q in = Q out  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

So from the question :

Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)

[tex]\tt Q~supplied=m.c\Delta T(water)+m.c\Delta T(vessel)\\\\Q~supplied=375\times 4.18\times (100-35)+532\times 0.51(100-35)\\\\Q~supplied=101887.5+17635.8=119523.3~J[/tex]

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{2.39 \times {10}^{23} }{6.02 \times {10}^{23} } \\ = 0.39700996...[/tex]
