In a one word response, mitosis.
In an explanation: Before the replication process, an ordinary sex cell contains only has 23 chromosomes. That is half the amount of a normal cell. So when the cells join together they make up the 46 pairs. Then through replication and division(i.e mitosis), the cells are copied to form in short a tiny human. You then forever live with the same amount of chromosomes in your normal cells.
Answer;
C. a scanning electron microscope
Explanation;
-Electron microscopy is a technique for obtaining high resolution images of biological and non-biological specimens. There are two main types of electron microscope; the transmission EM and the scanning EM.
-Scanning electron microscopes allow scientists to find the shape and surface texture of extremely small objects, including a paperclip, a bedbug, or even an atom.
-These microscopes slide a beam of electrons across the surface of a specimen, producing detailed maps of the surface of objects.
Answer:
Being cylindrical, phospholipid molecules spontaneously form bilayers in aqueous environments. In this energetically most-favorable arrangement, the hydrophilic heads face the water at each surface of the bilayer, and the hydrophobic tails are shielded from the water in the interior.

<span>Lipids doesn't have monomers while carbohydrates does and can be categorised into three: monosaccharide, disaccharide, polysaccharide.
For a polymer to be considered a polymer it must be comprised of monomers like proteins and other macromolecules.
There
are 20 different type of monomers present in proteins. Amino acids are
in reality the monomers of proteins. Out of the 20 amino acids, only 9
are considered essential. The other 11 are of little use to the humans.
The nine of the essential amino acids required by humans are Tryptophan,
lysine, Histidine, Isoleucine, Valine, Threonine, Phenylalanine,
Methionine and Leucine. The amino acids combine with one another to form
different types of proteins. These proteins satisfy a number of our
physical functional needs.<span> </span></span>
