Answer:
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. ... That means a white dwarf is 200,000 times as dense.
Explanation:
they are cold
they are about the size of Earth
these both are not true
Building blocks are the small units that make the larger, more complex molecule. The building block of protein is an amino acid and lipids are fatty acids and glycerols.
<h3>What are proteins and lipids?</h3>
Proteins and lipids are the biomolecules that are involved in major reactions in the living system. They are composed of smaller subunits joined together by bonds.
Proteins are molecules made up of amino acids linked by the peptide bonds to form the chain of proteins that plays a crucial role in cell functioning.
Lipids are composed of fatty acids and glycerol linked by the ester bond, essential for the storage of energy and in the composition of the membranes.
Therefore, proteins are composed of amino acids and lipids of fatty acids and glycerol.

The volume shown in the graduated cylinder according to the image would 28 mL. Thus, the correct option would be C.
In the cylinder, the top of the liquid formed a concave meniscus with the walls of the cylinder. Thus, the bottom of the meniscus would be read as this is the normal rule.
The rule is such that for liquids that form concave meniscus with the walls of cylinders, the bottom of the meniscus is read while it is the top of the meniscus for liquids that form convex meniscus with the walls of cylinders.
Hence, looking at the image, the bottom of the concave is on the 28 mL mark on the cylinder.
