What three identifying features of a chromosome are used to pair homologous chromosomes in a karyotype?.

Biology
1 answer:
OlgaM077 [116]2 years ago
8 0

Answer:

To "read" a set of chromosomes, scientists use three key features to identify their similarities and differences:

Size. This is the easiest way to tell chromosomes apart.

Banding pattern. The size and location of Giemsa bands make each chromosome unique.

Centromere position. Centromeres appear as a constriction.

What are the structural characteristics that give the phosphoanhydride bond its high-energy status?
Bas_tet [7]

Answer:

The answer to the given question out of the four options provided is given by:

Option a. Hydrolysis products are more resonance stabilized.

Explanation:

The answer selection to the above question can be justified as Phosphoanhydride on hydrolysis releases free high energy as the bonds formed by phosphoanhydride are the bonds with high energy.

Therefore, the product of hydrolysis after releasing this energy is more resonance stabilized.

Cells with a full set of chromosomes are referred to as diploid or 2n, whereas cells with half the chromosomes are haploid or n.
Papessa [141]

Answer:

  • Diploid → Prophase, metaphase, and anaphase
  • Haploid → Telophase

Explanation:

During prophase I,  chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n

During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n

During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n  

In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n

Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.

The two new cells are ready for meiosis II.

A synovial joint is surrounded by a two-layer ____________ which encloses a fluid-filled space called the ____________ . The out
galben [10]

A synovial joint is surrounded by a two layer <em>joint capsule</em> which encloses a fluid filled space called the <em>synovial cavity</em>. The outer layer of this structure consists of <em>dense connective tissue</em> which is continuous with the periosteum of each bone. The outer layer may be reinforced by <em>ligaments</em> which are bundles of collagenous fibers. Some of these bundles are part of the capsule while other are located outside of the capsule. By definition, the structures, such as some ligaments, that are located outside the capsule are called <em>accessory structures</em>. The inner layer of the joint capsule is the <em>synovial membrane</em>, consisting of loose connective tissue. The inner lining of the joint capsule secretes a fluid called <em>synovial fluid</em>. This fluid is viscous, and moistens and lubricates the surfaces within the joint capsule
