On number two of the second file, mass is how many atoms there are, while weight is how much he gravitational body the object is on (if any) pulls the object (which is why we weigh nothing in space).
For the first question of the second image, A's answer would be 1,800 g/300cm^3, or 600g/cm^3.
For B, .250g/cm^3 * 200cm^3 is 50g.
For the table: Density is how compact the matter of an object is in a certain amount of space. An example would be that water has a density of 1g/cm^3
Mass is how much matter there IS, for example, a car has more mass than an orange.
Volume is the quantity of 3d space an object has or how "big" it is. For example, a cubed building is the length of one side to the third power
Weight is how much gravity is pulling on an object, and not related to how much stuff an object has other than that, for example, you might weigh 100 kilograms on Earth but none is space, and your matter hasn't changed.
I hope you enjoyed your answer.

For the transport of metals across the fluids and the body membranes, the intracellular potential is needed. But sometimes due to the toxicity of lead, the process is affected especially in the digestive tract.
How bioaccessibility of lead is affected in the human digestive tract?
Both the organic (tetra alkyl lead) and inorganic forms of lead have been demonstrated to be extremely hazardous in experimental studies. This lead absorption, which typically occurs by inhalation or food contamination, is influenced by variables including absorption rate, particle size, and solubility. The majority of the lead that is inhaled is in tissues that contain minerals. Following speciation, Lead's binding power increases in comparison to Zinc and Calcium, which has an impact on fluidity. Lead's bioavailability seems to be reduced when food is present. The concentration of lead may also be reduced by pyromorphite. Since solid state speciation happens when the pH is between 6 and 7, Now, this results in a change in circumstances from the stomach to the intestinal tract, leading lead to transform into lead phosphate, which is less soluble and reduces bioaccessibility.

The cells are generally the same but animal cells don't have a cell wall and also there vacuole is smaller than plants
After the 1st half-life 250 g of the radioactive material will be left.
<span>After the 2nd half-life 125 g of the radioactive material will be left. </span>
<span>After the 3rd half-life 62.5 g of the radioactive material will be left. </span>
<span>Therefore after 60 minutes, 3 half lives would have occurred. </span>
<span>Therefore the half-life = 60 / 3 = 20 minutes when 250 grams of the original material would have remained radioactive. </span>
<span>Therefore the answer is A) About 250 gram of the material decayed in 20 minutes.</span>
