Answer:
0.75 g/cm³
Explanation:
Given data:
Mass of wooden block = 180 g
Length of block = 10 cm
Width of block = 6 cm
Height or thickness = 4 cm
Density of block = ?
Solution:
Volume of block = height × length × width
Volume of block = 4 cm × 10 cm× 6 cm
Volume of block = 240 cm³
Density of block:
density = mass/ volume
d = 180 g/ 240 cm³
d = 0.75 g/cm³

<span>First, you should know that the four properties given are used in the identification of minerals. Hardness is the level of difficulty with which the smooth surface of a mineral sample may be scratched. Cleavage is how the crystal splits along a plane. Color is the result of the reflection of the light by the atoms and Streak is the color displayed by the mineral when it is crushed to a fine powder, while impurity contents affect the color, they do not affect the streak. So, streak is a better technique to identify minerals than colors. And the other two, hardness and cleavage are well known as being very useful. So, the least useful is color. Answer: option D.) color.</span>
In the given condition where the thylakoids are isolated from the chloroplasts to make the pH of the thylakoid space acidic, the isolated thylakoid will form the ATP.
ATP is also referred to as Adenosine Triphosphate and is correctly called as the energy currency of the cell as it is responsible molecule for carrying the energy units in the cell. When the isolated thylakoids are made to transfer in the pH = 8 basic solution, then the acidic lumen of the chloroplast will be having a higher concentration of H⁺ ions. When they are placed in the basic solution then the H⁺ ions will move out because of the occurrence of concentration gradient which is higher in the lumen than the surrounding. The chloroplasts will now bear synthesis of ATP. Therefore, the isolated thylakoid is able to make ATP when the lumen is acidic, and the surroundings are made basic in nature.
Thus, the thylakoid which is isolated will bear the synthesis of ATP.

Answer:2 ml.
Explanation:Volume. 2.5 g/ml = 5g/Volume. Volume = 5g/(2.5 g/ml). = 2 ml.
