1) The main difference between a prokaryotic cell and a eukaryotic cell isD) the presence of a true nucleus.
2) Which type of cell contains DNA enclosed in a nucleus?
C) plasmid
3) Viruses CANNOT
B) live in bacteria.
Hope this helps.
It will be C because if a lower energy bonds are formed from breaking higher energy bonds then there will be excess energy to fuel other processes.
Complete question: What situation might develop in a population having some plants whose flowers open at midday and other plants whose flowers open late in the day?
a. Temporal isolation
b. Geographic isolation
c. Behavioral isolation
d. Genetic drift
Answer:
a. Temporal isolation
Explanation:
Temporal isolation is one of several mechanisms of reproductive isolation. Temporal isolation occurs when some organisms of a population exhibit different timing of reproductive maturity. It also occurs when some members of a population reproduce at a different time from the others. This does not allow interbreeding between them.
When plants of a population open flower at a different time of day, cross-pollination would not occur between these plants. This represents temporal isolation.
<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.
