Hello!
Red stars have a larger radius and luminosity than a main sequence (aka dwarf) star of the same surface temperature.
The thin tubes that form between the centrioles during mitosis are the spindle fibres. Spindle fibers originates from a protein structure that divides the genetic material in a cell. They are necessary for the equal division of the chromosomes in a parental cell into two daughter cells during bth types of nuclear division (mitosis and meiosis). During the process of mitosis they are called mitotic spindles.
Cell interprets a genetic code by reading and interpreting each codon which corresponds to a single amino acid. each three letter "word" in mRNA is a codon. ... Protein synthesis creates proteins from amino acids. DNA replication creates a new DNA molecule from an existing one
<span>Lipids are fat,play multiple roles in the body. Fats are broken down in the digestive tract to form individual fatty acids and cholesterol molecules. Fatty acids and cholesterol are key components of the membranes that surround all cells
</span><span>Proteins are large and fairly complex molecules that are responsible for doing most of the work that occurs in cells. They also are needed to maintain the structure of cells and are critical for the function and regulation of all of the body's tissues. T</span>
Ok, I'm not fully sure but answer B sound right, so I think it's right
