Answer:
What is the difference between a pupa and the adult stage of a butterfly?
Adult butterfly has reaches its maximum growth stage while pupa is still growing and will develop into caterpillar before metamorphosing into adult butterfly, Adult has colorful wings while pupa stage does not
Explanation:
A) Each DNA nucleotide is made up of a sugar, a phosphate group ... Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are ... In the case of RNA, the five-carbon sugar is ribose. DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C. In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff’s rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds. The two strands are anti-parallel in nature; that is, one strand will have the 3′ carbon of the sugar in the “upward” position, whereas the other strand will have the 5′ carbon in the upward position. The diameter of the DNA double helix is uniform throughout because a purine (two rings) always pairs with a pyrimidine (one ring) and their combined lengths are always equal.
Answer:
b. synthesis of cellular membrane components
Explanation:
Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.
The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).
Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles
While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.
Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
