Intel Core i5-2520M Computer Technology Review

The newly released Intel Core i5-2520M computer processor features integrated graphics controller also known as Intel HD Graphics 3000 chipset which, however, shares the fast level 3 cache with the CPU cores. This integrated graphics controller is clocked from 650 to 1300MHz with Turbo Boost technology.

In addition, this ultra high-end dual-core Intel Core i5-2520M processor is also based on Sandy Bridge architecture and offers HyperThreading technology in order to handle 4 threads at once. This 2nd generation Core i5 processor has 128 KB Level 1 Cache, 512 KB Level 2 Cache, and 3MB level 3 cache and features a base clock speed of 2.5 GHz but because of TurboBoost technology its speed can increase up to 3 GHz when 2 cores are active and 3.2 GHz when only 1 core is active.

Lastely, the Intel Core i5-2520M has a PassMark rating of 3586, which is quite faster compared to its sibling Core i5-2410M with a rating of 3350. This processor has a TDP rating of 35W.

Get the Best Ultraportable Laptop Display Screen Resolution

Ultraportable Laptop display screens are now available in more and more types of resolutions. You currently have the now-humdrum standard high definition (1,366 by 768 pixels) in budget models to full HD (1,920 by 1,080) and even Ultra HD or 4K (3,840 by 2,160).

However, the lower-resolution screens are most frequently found in entry-level systems simply because they're the least-expensive option. They work well enough for reading and typing text, and YouTube often defaults to something lower than full HD, anyway, so less discerning users can get by just fine. But a 1,366-by-768-pixel screen is best avoided here in 2020 if you can help it.

Full HD (often referred to as 1080p) screens are what you should expect on many budget systems, all midrange models, and some premium ultraportables. The 1080p display is becoming standard enough that even some cheaper options now offer them, a far cry from the situation just a few years ago, when 1,366 by 768 was the norm.

These Laptop display screens offer support for full-1080p video playback and are better equipped for multitasking, since you can fit more readable text and two side-by-side windows onto a 13- or 14-inch 1080p screen. This is a sharp, true HD resolution, ideal for most daily use.

X-Linked and Y-Linked Traits

In humans, males and females are represented by different sex chromosomes


• Males have one (1)  X chromosome and one Y chromosome in the nucleus of their cells.

• Females have two (2) X chromosomes in the nucleus of their cells.




The expression pattern of the trait differs in males and female, is dependent on whether the trait is dominant or recessive.




X-linked traits are traits where the genes for the trait is found on the X chromosome, while a

Y-linked traits is when the gene for the trait is found on the Y chromosome.




Sex-influenced trait in a diploid organism have expression which are affected by an individual’s biological sex and occurs at a higher frequency in one sex over the other



Sex-limited traits in a diploid organism have expression that are limited to just one biological sex 




Example.
Hemophilia is a rare blood condition where people do not have the clotting factor which enables their blood to clot when bleeding. It is an an X-linked recessive trait.


Problem Exercise :

When Prince Albert of Saxe-Coburg and Gotha married Queen Victoria of United Kingdom, they had nine children (four boys and five girls).
 
On March 27, 1884, one of Queen Victoria's sons fell down some stairs at a yacht club in southern France. The accident was minor; Prince Leopold suffered nothing more than a few bumps and bruises. But the 31-year-old Duke of Albany had hemophilia or the royal bleeding disease.

Queen Victoria passed the disease into her three children, Alice, Beatrice and Leopold. Prince Leopold the only one afflicted with hemophilia died from the post-accident hemorrhage when he was 31.


If only Prince Leopold was afflicted with the disease,

a.) determine his genotype.


b.) What could be the genotypes of the Prince Albert and Queen Victoria?


c.) Is it possible that each daughter could have been a carrier?
