B. Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.

Explanation:

A major difference between a plant cell and an animal cell is presence of chloroplasts in plant cells. Another key difference between plant and animal cells is the presence of a cell wall in plant cells. Both structures are absent in an animal cells.

The cell wall surrounds the plasma membrane of plant cells. This helps to provide the required tensile strength and protection against mechanical and osmotic stress.

Cell walls also help plants to maintain shape and rigidity.

The plant cell has a cell wall and chloroplast, while the animal cell lacks both of them. Thus, option B is correct.

The cell has been the smallest unit of life that has been performing varying functions with the help of different organelles.

The plant cell has been exposed to harsh environmental conditions, thus has been consisting of the cell wall along with the cell membrane. However, animal cell lacks a cell wall.

The food has been processed in the plant cells with the help of photosynthesis that required chlorophyll. The chlorophyll has been consisted in the chloroplast. Thus plants cell have consisted of chloroplast, however, animal cells lack chlorophyll as well as chloroplasts.

Thus, the plant cell has a cell wall and chloroplast, while the animal cell lacks both of them. Thus, option B is correct.

The role of the forensic chemist in the Pan Am Flight 103 investigation was primarily focused on identifying the explosive used, which is crucial in determining the cause of the explosion and providing valuable evidence for the investigation.

The role of the forensic chemist in the Pan Am Flight 103 investigation involved identifying the explosive used. In this case, the forensic chemist would have analyzed the debris from the wreckage to determine the type of explosive that was used to cause the explosion.

To identify the explosive, the forensic chemist would have used various techniques, such as spectroscopy and chromatography, to analyze the chemical composition of the debris. By comparing the results with known explosives, the forensic chemist would have been able to determine the specific type of explosive used.

The identification of the explosive is crucial in the investigation as it helps in determining the cause of the explosion and provides valuable information about the perpetrators. Different types of explosives leave distinct chemical signatures, which can be used to link the explosion to a specific group or individual.

In addition to identifying the explosive, the forensic chemist may have also been involved in determining the cause of death of the victims. This could include analyzing autopsy samples for the presence of explosive residue or other chemical substances that could have contributed to the deaths.

It's important to note that while identifying the explosive and determining the cause of death are key responsibilities of a forensic chemist, other experts such as forensic pathologists and dental professionals would have been involved in identifying the victims from dental records and reconstructing the accident.

The volume of carbon dioxide produced when 10.0 L of oxygen is consumed is 6.67 L of CO2 (rounded to two decimal places).

Given balanced equation: C2H4(g) + 3 O2(g) → 2 CO2(g) + 2 H2O(g)The molar volume of all gases at standard temperature and pressure is 22.4 L/mol.Using the balanced equation, we can find the ratio of the volume of oxygen used to carbon dioxide produced.C2H4(g) + 3 O2(g) → 2 CO2(g) + 2 H2O(g)3 moles of O2 produce 2 moles of CO2So, 1 mole of O2 produces (2/3) moles of CO2 or 1 mole of CO2 produces (3/2) moles of O2.

To find the volume of carbon dioxide produced when 10.0 L of oxygen is consumed, we need to use the mole ratio:3 mol O2 → 2 mol CO22/3 mol CO2 is produced by 3 mol O210.0 L of O2 is consumed, which is equal to 10.0/22.4 = 0.4464 moles of O2Thus, using the mole ratio:0.4464 mol O2 × (2/3) mol CO2/1 mol O2 = 0.2976 mol CO2The volume of 0.2976 mol CO2 is:0.2976 mol CO2 × 22.4 L/mol = 6.67 L of CO2 (rounded to two decimal places).

The given chloride level in Michelle's blood is 0.55 g/dL. Now we need to convert this value into milliequivalents per liter.

Chloride has a molar mass of 35.45 g/mol. The equation for calculating milliequivalents per liter is:milliequivalents per liter (mEq/L) = (mass in g / molar mass) x 10So, milliequivalents per liter (mEq/L) of Michelle's blood is:0.55 g/dL = 0.55 x 10 / 35.45 mEq/L (since 1 dL = 1000 mL)0.55 x 10 / 35.45 ≈ 0.1561 (rounded to four significant figures)So, the value of chloride level in milliequivalents per liter in Michelle's blood is approximately 0.1561 mEq/L (to two significant figures, the answer is 0.16 mEq/L).Thus, the correct answer is IVAL 0.16 mEq/L.

Fermentation is a metabolic process in which a reactant, usually sugar, is broken down into simpler components, such as alcohol or acids. The reactants of fermentation are usually sugar, starch, or proteins and the products are usually alcohol or acids and occur in the cytoplasm of cells.

Fermentation typically occurs in the cytoplasm of cells, and the enzyme responsible for the process is called an 'alcohol dehydrogenase.' Fermentation requires no external source of energy, and is an anaerobic process, meaning that it does not require oxygen.

The fermentation process begins with the breakdown of a sugar molecule, such as glucose, into two molecules of pyruvate. During this process, two molecules of NADH are also produced. The pyruvate molecules then undergo a process called 'decarboxylation,' where the carboxyl group of the pyruvate is removed, forming an acetaldehyde molecule and releasing carbon dioxide as a waste product.

The acetaldehyde molecule is then converted into ethanol by the enzyme alcohol dehydrogenase. The two NADH molecules are also converted into two NAD+ molecules, which can then be used in other metabolic processes. The end product of fermentation is ethanol and carbon dioxide.

In summary, fermentation is a metabolic process that involves the breakdown of a reactant such as sugar or starch into simpler components, such as alcohol or acids, occurring in the cytoplasm of cells.

A metal ion occurs whenever a metal gives up the outermost electrons to obtain a full octet. Calcium (Ca) will become a cation when it loses two electrons from of the outermost energy shell.

The correct answer to this question is To prevent water from evaporating we should water in the morning.

As the plant has time to dry before the sun sets, morning watering is really preferable to evening watering. Water tends to rest in the soil, around the roots, and on the leaves at night, which facilitates insect proliferation, rot, and fungal growth. During the heat of the day it evaporates before it can reach the roots, water your plants early in the morning or late at night. To help the soil retain moisture, sprinkle it with water-retentive crystals.

The molar concentration of Al(OH)₃ in the solution is 1.61 M.

we need to calculate the number of moles of Al(OH)3 in the solution:

Number of moles of Al(OH)₃ = mass of Al(OH)3 / molar mass of Al(OH)3

Molar mass of Al(OH)₃ = (1 x atomic mass of Al) + (3 x atomic mass of O) + (3 x atomic mass of H)

Molar mass of Al(OH)₃ = (1 x 26.98 g/mol) + (3 x 16.00 g/mol) + (3 x 1.01 g/mol) = 78.00 g/mol

Number of moles of Al(OH)₃ = 62.7 g / 78.00 g/mol = 0.804 moles

Next, we need to calculate the volume of the solution in liters:

Volume of solution = 500.0 mL = 500.0 mL x (1 L/1000 mL) = 0.500 L

Finally, we can calculate the molar concentration of Al(OH)₃

Molarity = moles of solute/volume of solution in liters

Molarity = 0.804 moles / 0.500 L = 1.61 M

Therefore, the molar concentration of Al(OH)₃ in the solution is 1.61 M.
