Answer:
The needed options are
A. an uncontrolled experiment
B. intuitive reasoning
C. extrapolation
D. replication
E. exploration
The ANSWER is D. replication
Explanation:
Replication in research means using the same method and methodology in proximity to the original research work.
It helps in bringing, validating and proving the original study is up-to-date. It may be done using the same exact methods in a different cultural settings, location or different research subjects to determine if the original experimental results is up-to-date.
Answer:
5 bases
Explanation:
If there are 17 amino acids and only 2 bases that can be combined in order to make a codon then:
for 4 bases 
is 16 and it is not enough combination for all 17 amino acids
for 5 bases 
is 25 combinations (meaning that more than one codon could code for the same amino acid).
Answer:
I believe the answer is C) Carbohydrate
Explanation:
Sugar gives you fast energy, and it is not long term like a lipid, so the answer is C.
Answer:
in the S phase of the cell cycle
Explanation:
<em>Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have 1.5 times more DNA than G1 phase cells. The cells of this group are _____.</em>
The cell cycle has two main stages which is the interphase and the M phase.
While the M phase is characterized by active division, the interphase consists of G0 phase which is entirely a resting phase for cells that do not need to divide ordinarily, G1 phase which is a phase for cell drowth and development, S phase which is a phase for DNA synthesis or replication and G2 phase which is a phase for protein synthesis.
Hence, cells in the S phase and G2 phase of the cell cycle are expected to have more DNA than cells in the G0 and G1 phase.
<em>Essentially, the amount of DNA is doubled in the S phase. Therefore, if the cell group have 1.5 times more DNA than G1 phase cells, it means the cells are still in S phase.</em>
