Liono4ka [1.6K]

Answer:

Right posterior oblique position.

Explanation:

The obtruator foramen is the opening created by the ischium and pubis bones of the pelvis. This obtruator is triangle in shape in females and oval shape in males.

When the right obturator foramen has been narrowed,  the coccyx and sacrum has been rotated toward the left hip and the right ischial spine has been demonstrated without the pelvic brim of the superimposition. This represents the RPO (right posterior oblique position.

kotykmax [81]

Answer:

False. Bone can be classified as a connective tissue because it provides support and structure to the body.

Explanation:

Connective tissue is those tissues that fill spaces between organs and other tissues, and also provide support to the organism. It is characterized by the presence of different types of cells separated by intercellular material synthesized by them.

The bony tissue is the principal structural and supportive connective tissue that differs from the other connective tissues because its extracellular matrix is mineralized, which makes it possible to accomplish its support and protection function due to its rigidity and hardness. The mineral that deposits in the osteoid matrix is the calcium phosphate, composing hydroxyapatite crystals. The bony tissue is a storage site of calcium and phosphate, which are available for maintaining constant the calcium blood levels according to the individual physiological needs.

Galina-37 [17]

Answer:

It seems that a reciprocal translocation is going on.

Explanation:

A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.

According to this, there are different types of translocations:

  • Intrachromosomal translocations:
  1. Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569
  2. Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789
  • Extrachromosomal translocations:
  1. Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one.
  2. Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.

Reciprocal translocations might be:

  1. Fraternal: the interchange occurs among homologous chromosomes
  2. External: the interchange occurs among non-homologous chromosomes

Reciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed.  This association is a quadrivalent structure.

During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.
