<h3><u>Answer and Explanation</u>;</h3>
- Purines: Heterocyclic rings are synthesized one atom at a time, first atom attached to ribose phosphate (source is PRPP) and then all the other atoms are added .
- Pyrimidines: Common intermediate, orotate, synthesized first, then orotate is attached to ribose phosphate (source is PRPP or 5-Phosphoribosyl-1-pyrophosphate).

<span>Notice that diploid cells which 18 are the complete number of chromosome pair of the organism. This usually happens under cell divison –mitosis which process of replicating oneself to produce another like cell. Meiosis occurs in gametes, sex cells. Their respectively called spermatogenesis (sperm cells) and oogenesis (egg cells). These cell division –meiosis produces haploid cells, in which in words “half” from the complete cell chromosome number, hence, these </span>haploid cells<span> only produce half number or one set of chromosome (9) instead of the complete pair which in this case, 18.<span>

F(x) = x
f(x) = x^2
f(x) = 2^x
1) Which functions intersect?
2) How many points of intersection are there?
3) What does a point of intersection mean?
Answer:
c. Ribosomes
Explanation:
Ribosomes can be found in eukaryotic and prokaryotic cells. In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm. In both cells, ribosomes intertwine into an RNA molecule and form polysomes.
Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.
