Answer:
Presence of chlorophyll pigment in the leaves and cell walls were made of cellulose
Explanation:
The first plants that appeared on the land areas were comprised of the main component known as the cellulose that forms the cell wall of the plants and is responsible for making the various parts of plants such as branches, plant stems, and leaves, stronger and supportive.
In addition to this, the leaves of these primitive plants were comprised of green pigments known as chlorophyll that absorbs the sunlight and CO₂, and helps the plants in preparing the food for themselves as well as for the consumers, and also liberates oxygen (O₂) with it.
Thus, these are the two common characteristics that supported the idea that the primitive land plants had a relation with the green algae.
Odd question as there is multiple types of tissue that could be tested. Is there any additional information for the question?
Most likely though, it’s epithelial tissue.
Answer:
C. exact same type of alleles
1) Mice not radio waved.
2) Radio
3) Strength of mice
4) Maybe inconclusive.
5) Improves strength
Explanation:
- Control Group - Mice not radio waved.
- Independent Variable - radio.
- Dependent Variable - Strength of mice.
- What should Bart's conclusion be? Maybe inconclusive.
- How could Bart's experiment be improved? Improves strength
Experimental setup
setup that is testing a hypothesis using a variable. In most cases only one variable should be tested at a time.
Control Setup
setup that is identical to the experimental setup, only it does not contain a variable.
Independent Variable
The one factor that is change by the person doing the experiment
Dependent Variable
The factor which is measured in the experiment
Constant
all the factor that stay the same in an experiment.
