Compared to when the cosmic microwave background was first released, the radiation of the cosmic microwave background today is fainter and has most of its photons at longer wavelengths

<h3>What about Cosmic microwave background?</h3>
  • The cosmic microwave background is electromagnetic radiation that was produced during the early universe and is frequently referred to as "relic radiation" in Big Bang cosmology.
  • All of space is filled with the feeble cosmic background radiation, or CMB.
  • It is the oldest electromagnetic radiation in the cosmos, dating to the era of recombination when the first atoms were created, making it a significant source of information about the early universe.
  • The backdrop (the area between stars and galaxies) is completely dark when using a conventional optical telescope.
  • A sufficiently sensitive radio telescope, however, detects a very faint background glow that is essentially uniform and unrelated to any stars, galaxies, or other objects.
  • The microwave region of the radio is where this glow is greatest.

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.

Which antibody identified in prenatal specimens is never a cause of hemolytic disease of the fetus and newborn
Ratling [72]

Antibody identified in prenatal specimens is never a cause of hemolytic disease of the fetus and newborn is Anti-B.

Antibodies directed to antigens of the Lewis blood organization device. The Lewis antigens are glycoproteins which can be determined on the surface of many cells and secreted in numerous body fluids.

Anti-B may be obviously happening arising without stimulus through transfusion or being pregnant related red blood cell exposure or can be an immune stimulated antibody. In either case, it is predominantly an IgM antibody with a few related IgG element and frequently happens in affiliation with other antibodies.

Anti-E is generally an IgG antibody reactive through antiglobulin or enzyme techniques. a few examples have an IgM aspect that causes direct agglutination of E-high quality red cells. approximately of random D-wonderful bloods.
