Answer:
Homologous pairs of chromosomes are lined up independently of other such pairs during <u>metaphase I.</u>
Explanation:
Meiosis is a special type of nuclear division that occurs only in organisms with sexual reproduction. The meyotic division gives rise to gametes.
The division begins just after the chromosome DNA has replicated in the S phase. Each chromosome is made up of two identical sister chromatids joined by their centromere. However, chromosomes are not kept separate in the nucleus, but instead bind to their homologous partners. This union called synapse, occurs during prophase I.
In metaphase I, the pairs of chromosomes are aligned in the spindle Ecuador, that is, during this stage, the homologous pairs are aligned in the metaphase plate (which is the equatorial plane of the achromatic spindle) for separation.
During anaphase I, the members are directed to the opposite poles of the cell. Telophase I, this phase begins with the arrival of chromosomes at the poles and with the formation of a nuclear envelope around each group of chromosomes. During Profase II, the nuclear membrane (if formed during Telophase I) dissolves, and spindle fibers appear.
The first meyotic metaphase and anaphase is usually completed in a short time to give rise to the phases of the second division (metaphase II and anaphase II) , which is a mitosis during which the centromeres divide and the chromatides move towards opposite poles to become gamete chromosomes. In telophase II, cytokinesis separates cells.
Answer:
C) layering, directional pressure
Explanation:
The foliated metamorphic rocks are those rocks subjected to heat and pressure during metamorphism, characterized by presenting a parallel alignment of minerals, which gives the rock an appearance of layers or bands.
I think the answer is Eliminates waste
Answer:
With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude. On top of Mount Everest, which is the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level.
T86.49, C80.2, C22.0 codes are reported.
<h3>What issues arise following liver transplantation?</h3>
- Some cancers are more likely to develop after a transplant. For liver transplant recipients, cancer is a substantial cause of sickness and mortality.
- Nearly all malignancies are more likely to occur after a liver transplant, but skin cancer, lymphoma, and cancers linked to smoking are more likely to do so.
<h3>What liver transplant problem occurs most frequently?</h3>
Biliary problems remain the most frequent postoperative technical complication despite all advancements in transplant patient care and surgical methods, with an estimated prevalence of 15% or less in deceased donors and up to 30% in living donor or split liver transplant.
