Answer: Ribose nucleotides and the nitrogenous bases
Explanation: RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

Answer:
b. phospholipid bilayer of membrane
Explanation:
The phospholipid bilayer evidently has in its structure mainly phospholipids, alcohol compounds and fatty acids.
Each molecule in the membrane phospholipid bilayer has two heads and a tail, both heads being hydrophilic (having affinity for water) and the tail being hydrophobic (having no affinity for water, and therefore repelling it).
This structure, with the heads, which are hydrophilic facing the intracellular and extracellular environments of cells, thus prevents the passage of polar compounds.
The answer would be no, because if evolution did occur in this situation, then habitats could just as well change, and evolution helps organisms to adapt to change.
<u>Answer</u>: C. competency and proficiency
<em>Competency and proficiency’ guiding principle of forensic science states that a forensic scientist should be committed to lifelong learning.
</em>
<u>Explanation:</u>
A forensic scientist should be well aware of the <em>new technologies</em> and should have the expertise in using this new technology and equipment. The seriousness of the role that a <em>forensic scientist</em> is engaged in makes it necessary for him to be a continuous learner throughout his lifetime.
<em>Professionalism guiding principle</em> explains the need for a forensic scientist to remain impartial and conduct fair examinations. Clear communication principle mentions the importance of accuracy and clarity in a <em>forensic science report.
