Sudan changes to deep orange or red in the presence of lipids. Sudan in not soluble in water lipids will absorb sudan's particle that will cause the change in color. Lipids will form distinct fat layer in the solution. This can be done during experiment where a macromolecule is unknown. Application of this experiment applies in health such as during confirmation of excessive fat in stool. The affinity of this dye to the lipids is high and alcoholic solutions of sudan dye can also be used.
Answer:
water melon model is the first model y
so the correct answer sequence is y z w x
Answer: Checkpoints in the cell cycle A checkpoint is a moment in the eukaryotic cell cycle where the cell considers internal and external inputs before deciding whether or not to divide. There are other checkpoints, but the following are the three most important: At the G/S changeover, there is a G checkpoint.
Explanation:
knowledge!
Answer:
(a) <u>16</u> % of the alien genome is comprised of G.
(b) 17% of the alien genome is comprised of T.
(c) 17% of the alien genome is comprised of A.
(d) <u>22</u> % of the alien genome is comprised of X.
Explanation:
Assuming the alien follows Chargaff's rules which states that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases.
So if:
16% contains C ; 16 % pairs with G = 32% C-G pairing.
22% contains Y ; 22 % pairs with X = 44% X-Y pairing.
44% G-C + 32% X-Y = 76%
100%-76% = 34% the remaining should be split between T and A which is 17% each one.
