Answer:

C. 1 - IV (Independent Variable), 2 - constant, 3 - DV (Dependent Variable)

Explanation:

In science, an independent variable in an experiment is defined as a variable that is changed in order to see how it affects another variable. By analyzing the chart one can see that the pH is changed to see how the height of the plant changes. Thus, the pH is an independent variable.

A constant variable in an experiment is defined as a variable that remains constant throughout the entire experiment so that the researcher does not get conflicting results due to factors that were not relevant to the experiment. As the temperature indicated in the chart remains at 23 degrees Celsius for each and every plant, it is a constant variable.

A dependent variable in an experiment is defined as a variable that is the main focus of the experiment, where the researcher changes certain factors in order to observe how the variable changes. As the experiment features the researcher changing the pH value in order to determine how the height changes, the height is the dependent variable.

Thus, the answer is C.

Dna sequencing suggests that among the green algae, the __________ are most closely related to land plants.
makkiz [27]

DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.

<h3>What is DNA Sequencing ?</h3>

DNA Sequencing is a technique to determine the bases, nucleic acid sequence in the DNA. It is important to know the functions of genes, coding and non-coding part of proteins, identify the diseases, effectiveness of drug delivery etc.

<h3>What is Land plants and Stonewort ?</h3>

Stonewort is commonly known as Chara . It is a freshwater green algae which comes from the Charophyta division. Fossils of Charophytes shows that Stonewort is a type of algae which is 470 million years old.

Thus from the above conclusion we can say that DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.

How does limiting factors -such as space, light, and food- affect a population?
Anni [7]
These factors are essential for the growth and life span of the population of species in an ecosystem. The larger the space, the more light it obtains, and the more food the area produces; the larger the population of species in an ecosystem. having less space, light, and food, the results would be vice versa.
