Which activities? I want to say the nucleus as it is the control center of the cell, but this is a vague question.
Through crossing over during meiosis. In eukaryotic cells (us), there are these things called Histone proteins. TONS of these wrap around and form what eventually will be a chromosome in the nucleus of the cell. These chromosomes contain genes which contain genetic information in the form of DNA. If a trait is sex linked it will pass through to the offspring by meiosis, specifically during crossing over when homologous chromosomes exchange genetic information.
Presumptive Presumptive identification of microorganisms is defined as identification by the colony morphology, growth on selective media, gram stains, or up to three tests.

Answer:
1. Fibrocartilage.
2. dense regular connective tissue.
3. Hyaline cartilage
4. Dense irregular connective tissue.
5. Hyaline cartilage.
6. Fibrocartilage.
Explanation:
1. A meniscus is an example of an articular disc, which is composed of fibrocartilage.
2. Ligaments connect bone to bone and are composed of a dense regular connective tissue.
3. Hyaline cartilage is what makes up the articular cartilage of synovial joints.
4. Synovial joints have a joint capsule with a strong outer fibrous layer of dense irregular connective tissue.
5. Epiphyseal plates are the growth plates of long bones which are made up of hyaline cartilage and are an example of a synchondrosis.
6. A symphysis is an amphiarthrotic joint where fibrocartilage joins adjacent bones.
