Why can polyploidy individuals lead to speciation fairly quickly?

Biology
1 answer:
nekit [7.7K]3 years ago
8 0

Answer:

In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available,  events like mutation, recombination, DNA lose, are more probable to occur.

As the generations pass, the accumulation of these changes tend polyploid to speciation.

1. How much of downtown boston was original land? Where did the rest come from?
Hatshy [7]

History of Boston is described below.

Explanation:

  • When workers cut down Copp's hill the only thing they left untouched was the old three-acre burying ground. The city built a retaining wall around the graveyard to prevent it from eroding. In 1814, the Boston and Roxbury Mill Corporation built the Boston & Roxbury Mill Dam across the back bay
  • Originally called Tremontaine for the three hills in the area, the Puritans later changed the settlement's name to Boston, after the town in Lincolnshire, England, from which many Puritans originated.
  • South Boston, which was front and center in the battle, is no longer that close-knit old school “tough-as-nail” Irish Catholic enclave. “Southie,” as it is still fondly referred to, houses the world today flaunting some of the best restaurants and expensive housing in the city
  • Boston was founded in 1630 by English Puritans fleeing religious persecution. On 29 March 1630 a fleet of 11 ships carrying 700 people sailed from England to Massachusetts. They were led by John Winthrop (1588-1649). At first the people settled at Charlestown, which had been founded the year before.
  • Much of Boston's coastline is man-made land. The original shoreline, from 1630, is visible in dark green on this map. Land made between 1630 and 1995 is light green.Boston is a safe city, but as with any major city, you should take the usual safety precautions. Stay in well-populated areas, travel with others, especially at night, and keep track of your belongings. The tourist areas in Boston are generally safe, but some areas deserve mention.

Arteries are normally depicted as red while veins are colored blue due to the oxygenation of the blood being transported by each
Bogdan [553]
The exceptions to this rule are the pulmonary arteries and veins.  
<span>
The pulmonary artery is the one that carries deoxygenated blood from the right side of the heart (ventricle) to the lungs. On the other side, pulmonary veins transfer oxygenated blood from the lungs to the heart (left atrium).</span>

When enzyme action stops due to a build up of end product, this control is called..?
Papessa [141]
This control is called negative feedback. Mechanism of negative feedback. Each metabolic reaction or process is regulated by several enzymes. These enzymes control the rate of these reactions and thus are fundamental in maintaining homeostasis. In a negative-feedback pathways, the end product of  a pathway binds to the allosteric site of the first enzyme, closing its active site and blocking the rest of the reactions.

Below is a fragment of a DNA strand. A single primer is pictured below the strand in the gray box. 3'-ATACGACTAGTCGGGACCATATC-5'
Free_Kalibri [48]

Answer: 5'-TATGCTGATCAGCCCTGGTATAG-3'

Explanation:

DNA consists of 4 nucleotides; Adenine (A), Thymine (T), Cytosine (C) and Guanine (G), which serve as it's building block. The nucleotides are linked by 3', 5' phosphodiester bonds.

Phosphodiester bonds are bonds that join two nucleotides together.

Guanine (G) which always pairs with Cytosine (C) and Adenine (A) always pairs with Thymine (T). Percentage of A usually equals that of T while that of C usually equals G. This is known as Chargaff's rule.

So, to write the sequence of the complementary strand, you interchange the nucleotides with their corresponding partner.

Nostrana [21]
