Answer:
Field research and laboratory research are different from each other on various accounts. In a lab, the study is not on such a broader level as that on a field.
Some of the tools in a lab and a field study will be same because such tools cannot be changed. For example, for amplification of genes, PCR will be used whether a field research is being made or a lab research.
On the other hand, some of the tools will be different. For example, to study field plants we'll use quadrants for counting but in a lab, as a lesser number of plants are understudy so we won't need a quadrant.
I have my notes here about cell division which could hep you solve the problem on your own.
The first period of the first phase (interphase) of the cell cycle is G1, followed by S and G2, and finally by the mitotic phase.
During G1, the ploidy (the quantity of DNA molecules in the cell) can be represented by the formula 2n (n is the number of DNA molecules in a gamete cell of a given species). During S, DNA duplicates and the quantity of genetic material increases from 2n to 4n. During G2, the quantity remains the same: 4n. After the mitotic phase, the quantity of genetic material decreases to 2n in each daughter cell.
The answer is D.) Some environmental change has happened that favors the red flowers. The reason is, this is the most logical answer, the other are close, but D.) makes the most sense.
Answer: DNA is a double-stranded molecule, while RNA is a single-stranded molecule. ... DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.
