Answer:
Option C, Plant A
Explanation:
Control group within an experiment is the substance/organism or subject which shall enact as a base for comparison of impact of experiment created on the dependent variables.
Here, the impact of fertilizer is to be studied on plant. Thus, plant set up is dependent variable and amount of fertilizer is an independent variable. Out of all plants one plants is getting 0 amount of fertilizer hence this plant can be used for comparison with other plants which receives the fertilizers.

Answer:
The most appropriate tissue to join the pubic symphysis -that provides resistance to pressure and stretch during childbirth- is fibrocartilage.
Explanation:
Options for this question are:
- <em>A. Fibrocartilage.</em>
- <em>B. Elastic cartlage.</em>
- <em>C. Bone.</em>
- <em>D. Hyaline cartilage.</em>
Fibrocartilage is made up of dense connective tissue rich in type I collagen fibers, hyaluronic acid and proteoglycans, which give it resistance to stretching and pressure.
Some ligaments are formed by fibrocartilage, in addition to the intervertebral discs and the junction of the pubic symphysis, allowing a certain degree of mobility to the associated structures due to their semi-elastic properties.
Hyaline cartilage, also made up of connective tissue, is less resistant than fibrocartilage.
Bone cannot form this junction, because it would not allow the relative mobility of the joint.
The elastic cartilage allows for stretching but not the strength needed to join the pubic symphysis.
