Which of the following examples best represent the levels of organization from least to most complex in humans

Answer:

V = 9

Explanation:

n = 0.410

T = 47.0C (must be convert to K by + 273.15) = 320.15 K

P = 1.20 atm

R = 0.08205

V = ?

To solve this equation, we must follow the equation below:

PV = nRT

1.20 x V = 0.410 x 0.08205 x 320.15 K

1.20 x V = 10.8

V = 9

So the answer is 9.

Answer:

C

Explanation:

I picked C because the plant is interacting with the sun which is a nonliving part of the environment.

A, B and D are wrong because seaweed, horses, and trees are living things.

Answer:

C) A plant bending towards the sunlight

Explanation:

A) is incorrect because both the lobster and the seaweed are organisms! Likewise, so are B) and D). D) might seem a little tricky, but ultimately the squirrel is interacting with the tree by living inside it.

A plant bending towards the sunlight, however, is an organism having a response to a factor in its environment.

Answer:

Magma is not a factor responsible for the formation of sedimentary rock.

Explanation:

The new pressure is 1.08 atm

From the question, we are to determine the new pressure

Using the General gas equation,

[tex]\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}[/tex]

Where

From the given information,

P₁ = 1.5 atm

V₁ = 15 L

T₁ = 105 C = 105 + 273.15 = 378.15 K

V₂ = 25 L

T₂ = 181 C = 181 + 273.15 = 454.15 K

P₂ = ?

Putting the parameters into the equation, we get

[tex]\frac{1.5 \times 15}{378.15} = \frac{P_{2} \times 25 }{454.15}[/tex]

[tex]P_{2}= \frac{1.5 \times 15 \times 454.15}{25 \times 378.15}[/tex]

P₂ = 1.08 atm

Hence, the new pressure is 1.08 atm

If Liquid 1 has a higher specific heat than Liquid 2, then Liquid 1 will take longer to increase in temperature because the higher specific heat of a liquid needs more thermal energy for heating a liquid.

Specific heat of a substance refers to the quantity of heat that is required to raise the temperature of one gram of a substance by one Celsius degree so we can conclude that  Liquid 1 will take longer to increase in temperature

Bothe calcium and radium are second group elements in periodic table with two valence electrons. They exhibit similar physical and chemical properties.

All the elements in periodic table are classified into different groups and periods. The horizontal rows in periodic table are called periods. From left to right in a period the atomic number increases.

The vertical columns in the periodic table are called groups. Down a group the number of shells increases thereby the atomic size also. A group contains elements with same number of valence electrons and similar physical and chemical properties.

Calcium and radium are in the second group of periodic table and they are called the alkaline earth metals. Both contains two valence electrons and they will participate in chemical bonding by losing these two electrons and thus are divalent cations.

The standard cell notation for an Galvanic cell with aluminum and gold electrodes is Au(s)| Au³⁺  ||   Al³⁺| Al (s)

A device in which electrical energy is converted into chemical energy or chemical energy is converted into electric energy is called an Electrolytic cell

The electrolytic cell consists of two metallic electrodes and an electrolyte.

In this cell nomenclature, the electrode to the left of the salt bridge is always assumed to be the anode, and the accompanying half-equation is always stated as an oxidation , while right side is cathode and the half equation is Reduction.

Au(s) → Au³⁺(aq) + 3e⁻  ..........(oxidation)

Au³⁺(aq) + 3e⁻ →Au(s) ..............(reduction)

Explanation:

Using Charles's Law to solve this question: V1/T1 = V2/T2

V1 = 2.24L

T1 = 52C (covert to Kelvin by plus 273.15) = 325.15K

V2 = 1.66L

T2 = ?

V1/T1 = V2/T2 must change to V2×T1/V1 = T2

1.66 x 325.15/2.24 = V2

V2 = 240.96K ≈ 241K

The molality of the CaCl₂ solution given that 166.5 g of CaCl₂ dissolves in 3.5 Kg of water is 0.429 M

This is the defines as the mole of solute per unit mass (in Kilogram) of water.

Molality = mole / mass of water (in Kg)

The mole of 166.5 g of CaCl₂ can be obtained as illustrated below:

Mole = mass / molar mass

Mole of CaCl₂ = 166.5 / 111

Mole of CaCl₂ = 1.5 moles

The molality of the CaCl₂ solution can be obtained as illustrated below:

Molality = mole / mass of water (in Kg)

Molality of CaCl₂ = 1.5 / 3.5

Molality of CaCl₂ = 0.429 M

Thus, the molality of the solution is 0.429 M

Explanation:

The car is not moving / is at rest from section(s) e to f & a to b.

Here, from e to f & a to b, we can see in the distance-time graph that the car shows no motion & is present in the same direction even though the time changes. Hence, we can infer that the car is at rest.

If the line goes up then the speed increases, if it's moving down then the speed decreases & if the line is the same then the car is at rest.
