68027 cells from plant leaves would fit in a volume of 1.0cm3. Explanation: As 1cm=10mm , 1.0cm3=103mm3 or 1.0cm3=1000mm3. Hence number of palisade cells from plant leaves would fit in a volume of 1.0cm3 are 1000mm30.0147mm3.
The correct answer for the simple machine is, Lever
Answer:
to separate the compounds by gravity
Explanation:
Centrifuging is the process of separating compound in a liquid mixture by means of gravity and settling. This makes use of the density principle. In the process, the sample is added to the centrifuge. This is then rotated at a certain speed, say 50 rpm. The circular motion creates a force of gravity that pulls the compounds downwards. This then separate the compounds. The heaviest and most dense go down first, then the lighter particles on the top.

Answer:
A)adding heat to the system and having the system do work on the surroundings
Explanation:
The variation in the internal energy of a system (ΔU) is given by the First Law of Thermodynamics. See the equation below:
ΔU = Q + W
Q: Heat added (+) or removed (-) from the system
W: work done on (-) or done by (+) the system
If you add heat (Q +) and have the system do work (W +), you guarantee that th internal energy of the system will increase (ΔU +).
