1. Suzie's hypothesis (i.e. prediction of results) is that ferns which are placed in white light will grow to a taller height after two weeks than ferns which are placed in other coloured light or in a closet.

2. Her independent variable (the thing she changes to produce a result) is the kind of light that she places each plant in.

3. The dependent variable (the thing she measures) is the height of the plants after two weeks.

4. I would say her control group would be the plant placed in the closet, because every other group is exposed to some form of light.

5. I would say that Suzie has 4 experimental groups: white, red, blue, and green light.

6. The constant variables were the amount of water each plant was given, the initial height of the plants, the age of the plants, the species of fern, and what she planted the ferns in.

7. To determine how each fern did, Suzie could measure the height in addition to noting the appearance of all the plants. E.g. did any look paler than the others?

Part a - identifying the processes of replication, gene expression, and recombination this activity requires that you correctly

Naddika [18.5K]

I found the exercise on the internet with the images and brief descriptions. Attached is an image of it.

To the DNA replication bin:
-Image of one cell dividing into two cells, and the mother cell has its DNA being unfolded and replicated.
-"DNA -> 2DNA (copying one DNA molecule to make two identical DNA molecules)"

To the gene expression bin:
-Image of only one cell with some arrows within it indicating the gene expression flow: DNA -> mRNA -> protein
-"DNA->mRNA->protein"
-"transcription"
-"translation"

To the recombination bin:
-Image with two cells being one the donor and the other one the recipient. The recipient has DNA with different colours pretending to represent that its DNA has different origins.
-"transformation"
-"conjugation"
-"transduction"
