<h2>Tolerate Polyploidy</h2>

Explanation:

  • Various species display various degrees of resilience for polyploidy. For instance,<em> polyploids structure </em>at moderately high recurrence in <em>blossoming plants (1 for every 100,000 people)</em>, recommending that plants have a strikingly high <em>resistance for polyploidy.</em> This is likewise the situation for certain types of fish and frogs.  
  • Polyploidy is normal in plants than in creatures in light of the fact that in creatures sex assurance component includes <em>number and type sex chromosomes. </em>
  • Polyploidy will meddle with this component and subsequently it is seen once in a while in animals.This vegetative proliferation empowers increase of <em>polyploid plants.  </em>
  • Chromosomes can be divided by  by their such as <em>size,banding design number, centromere position. </em>
  • <em>Autosomes or "body chromosomes"</em> (the entirety of the non–sex chromosomes) are commonly found in the human karyotype sorted out in rough request of size from biggest (chromosome 1) to littlest (chromosome 22).  
  • The number and presence of chromosomes in a phone is known as a karyotype.
  • A karyotype must be seen and examined with a magnifying lens. Karyotype investigation can uncover anomalies, for example, <em>missing chromosomes, additional chromosomes, erasures, duplications, and translocations.</em>

If a cell in metaphase of mitosis is fused with a cell in the G$$_1$$ phase of the cell cycle, the second nucleus will also begi
nalin [4]

Answer:

C. Molecules such as cyclins are in high concentration in the cytoplasm of a dividing cell and will signal the fused cells nucleus to undergo mitosis

Explanation:

Various stages of the cell cycle are under tight regulation. Specific proteins such as cyclins and cyclin-dependent protein kinases determine if the cell would progress from one stage of the cell cycle to the next. When a cell is in the metaphase, the cyclins specific for mitosis are present in a higher amount in the cell. These cyclins bind to the specific CDKs and activate them.

The activated CDKs then phosphorylate proteins that make the cell to move through various stages of mitosis. Therefore, fusing a G1 cell with a cell in metaphase of mitosis would trigger mitosis in the G1 cell due to the presence of mitosis specific cyclins in the second cell.

How does global warming lead to succession events?
MissTica

Answer:

Due to increase temperature and drought condition.

Explanation:

Succession refers to the changes occur in the structure of a biological community with the passage of time. Global warming has a great affect on the succession events because the vegetative cover present in that area vanished due to increase in temperature which is unbearable for the vegetation and also drought condition occurs in that area due to no rainfall. Instead of vegetative cover, a new plant specie formed which has the ability to exists in that environment.
