Meiosis Foldable Activity 515.2
Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

  • homologs pair off into bivalents
  • At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I  forming bivalents; tetrads are formed.
  • Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
  • then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

  • Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
  • independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
  • in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
  • Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

beks73 [17]

Answer:

Diarthroses are freely movable joints.

Explanation:

Rheumatology may be defined as the branch of medicine that mainly deals with therapy and diagnosis of the rheumatic disease. The individual specialized in this field is known as rheumatologist.

Diarthroses joint is also known as synovial joint and lined in continuous with the periosteum of the joined bones. The synovial fluid is filled in the synovial joint. The synovial joints provide the free movable joints that allow abduction, extension and adduction of the body parts.

Thus, the correct answer is option (d).
