Answer: 0.5 mm
Explanation: The smallest division that a common ruler has is 1 mm so any measurement taken is approximately accurate to a mm.
Uncertainty of any measuring instrument is the inaccuracy or lost of precision that occur due to its less divisions in an instrument
Uncertainty= Least Count /2
Uncertainty= 1 mm /2
Uncertainty= 0.5 mm
it means that measurement can be 2.3cm ± 0.5mm

Answer:
A) Fusion
Explanation:
Fusions of atoms heavier than hydrogen like helium takes place in the core of the star, at the core the temperature and density of gases is the greatest .
C. Light color became an adaptation in the surviving moths? Not fully sure.
Answer:
An instrument for measuring the density of liquids.
Explanation:
A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.
Thermohydrometers is one type of hydrometer.
