Researchers are investigating the effect of ph level in water on the breeding habits of the moon jellyfish. As part of a laboratory experiment, they will randomly assign one of three treatments, low ph , medium ph , or high ph , to the water in the tanks that hold the jellyfish.

Answers

Answer 1

In this experiment randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

In an experiment, variables are carefully controlled in order to ensure the reliability of the results. Usually, treatments are assigned randomly to experimental units. Randomization refers to the assignment of experimental units to groups by chance.

Randomization is important in this experiment because it  tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

Missing parts;

Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?

A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

B. Randomization will make up for improper experimental design, data collection, and analysis.

C. Randomization makes the analysis easier since the data can be entered into the computer in any order.

D. Randomization is required by statistical consultants before they will analyze the experiment.

E. Randomization means that the experiment would not need to be replicated

How many moles are represented by 12. 33 g of carbon dioxide?.

Answers

Explanation:

formula:

mass - moles = mass given ÷ molar mass

R.M.M of CO2 = 32 + 6 = 38

Molar mass of CO 2 = 38g (recall that r.m.m = molar mass)

38g of CO2 will produce 1 mole

therefore 12.33g will produce:

12.33÷38g (recall formula above)

answer: 0.324 moles

Find the measure of a negative angle coterminal with 95°.

Answers

The measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Thus, option (b) is correct.

What is coterminal?

Angles in common position (angles with the starting side on the positive x-axis) that have a shared terminal side are referred to as coterminal angles. It's as easy as subtracting or adding 360° or 2 to each inclination, depending on whether it's measured in degrees or trigonometric functions. There are an endless amount of coterminal angles to be discovered.

The measure of a negative angle coterminal with 95°

Ф + 360 n

n is any integer (negative or positive)

Ф = 95°,

- 3n is an integer,

The co-terminal angles of 95° are,

= 95° + 360° (-3n)

= 95° - (1080 n)° ; for any integer n.

As a result, the measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Therefore, option (b) is correct.

What should you do when a garbage can is nearly full.

Answers

Answer:

You can also place a false bottom inside the trash can to stop overfilling. To do that, simply place an object like a cardboard box underneath and outside the bag so that when it appears full it will not be as heavy as a bag that reached all the way to the bottom.

Explanation:

(winks and runs off)

When the garbage can is full, it is transferred into bigger dustbins that are placed outside the houses.

What is garbage management?

Domestic composting, recycling, reusing, and burning or burying of waste in their own yards are all examples of on-site household waste management. Off-site household waste management consists of delivering separated recyclables to drop-off locations, dumping at a landfill or in public trash cans, or making donations.

The environment is protected from the hazardous effects of the inorganic and biodegradable elements included in trash via waste management. Air pollution, soil erosion, and water poisoning can all result from improper waste management. If waste is collected and managed well, it can be recycled.

Therefore, when the trash container is full, it is moved into larger trash containers that are positioned outside the homes.

Explanation:

What mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C?.

Answers

Answer:

6.7 kg

Explanation:

(0) - (-5.8)= 5.8ºC

5.8 / 1.86 = 3.12 m C6 H12 O6

The molar mass of C6 H12 O6 is: 180.156 g/mol

3.12 * 12 kg * 180.156 g/mol = 6,745.041 g = 6.7 kg.

The mass of glucose solute dissolved in the solution is 6.739 Kg.

Recall that;

ΔT = K m i

ΔT = Freezing point depression

K =Freezing point depression constant = 1.86°C/mol

m = molality of the solution

i = Van't Hoff factor = 1 (molecular solution)

We have to find the freezing point depression from;

Freezing point depression = Freezing point of pure solvent - Freezing point of solution

Freezing point of pure water = 0°C

Freezing point of solution = -5. 8 ∘C

Freezing point depression = 0°C - (-5. 8 ∘C) = 5. 8 ∘C

Now;

m = ΔT/K i

m = 5. 8 ∘C/ 1.86°C/mol × 1

m = 3.12 m

But molality = number of moles of solute/mass of solvent in Kg

Molar mass of solute = 180 g/mol

Let the mass of solute be m

3.12 = m/180/12

3.12 = m/180 × 12

m = 3.12 × 180 × 12

m = 6739 g or 6.739 Kg

------------------------------

so the ratio of the area ABC to the area of ABD = (9*12/2)/(16*12/2) =  

= 9/16  

hope this helped!

mark me brainliest :D

The ratio of the area of ABC to the area of ABD is 9/16. The correct option is B.

What is the area?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.

The area of a triangle is the region bounded by its perimeter or its three sides. The area of a triangle can be calculated using the formula, where the base of the triangle is b and the height is h.

A = ½ (b × h)

The two areas will be calculated as:-

Area ABD = ( 1 / 2 )  x 16  x  12

Area ABC = (1 / 2 ) x  9  x  12

So the ratio of the area ABC to the area of ABD will be

= [ ( 1 / 2)  x 16  x  12 ]  ÷  [ (1 / 2 ) x  9  x  12 ]

=  9 / 16

Therefore, the area of ABC to the area of ABD is 9/16. The correct option is B.

Contrary to popular perception, underground rivers are not created by groundwater. Similar to how water fills a sponge, it fills the pores and cracks in subterranean materials like sand, gravel, and other rock.

Rock materials are referred to as aquifers if groundwater flows naturally out of them or if it can be pumped out of them. One of the most significant natural resources for the country is groundwater, which is found in aquifers beneath the Earth's surface.
