Compact Disc-Read-Only Memory, a type of optical disk capable of storing large amounts of data -- up to 1GB, although the most common size is 650MB (megabytes). A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 textpages.


 


Semiconductor memory is a type of semiconductor device tasked with storing data. There are two electronic data storage mediums that we can utilize, magnetic or optical.


 


Magnetic storage:


* Stores data in magnetic form.


* Affected by magnetic fields.


* Has high storage capacity.


* Doesn't use a laser to read/write data.


* Magnetic storage devices are; Hard disk , Floppy disk, Magnetic tape etc.


 


Optical storage:


* Stores data optically, uses laser to read/write.


* Not affected by magnetic fields.


* Has less storage than a hard disk.


* Data accessing is high, compared to a floppy disc.


* Optical storage devices are; CD-ROM,CD-R, CD-RW, DVD etc.


 


There is also volatile memory. This is memory that loses its data once power is cut off, while non-volatile memory retains data even without power.

Q:

Is a mushroom an autotroph?

A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

Mushrooms are heterotrophs. They are not plants or autotrophs.


 


Every living thing that exists need energy in order to live. This energy ultimately comes from the sun, and only plants, or autotrophs, can directly use this energy to make food. Those organisms that cannot harness the sun's energy are known as heterotrophs.


 


Mushrooms belong to kingdom Fungi and are heterotrophs because they decompose and consume nutrients from the soil. They are not green so they cannot photosynthesize



For this reason, mushrooms and all other fungi are heterotrophs.

Q:

The Ankle is a third-class lever.

A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

False. The ankle is not the third-class lever in the body.


 


Levers are typically labeled as first class, second class, or third class. All three types are found in the body, but most levers in the human body are third class.

First-class levers in the human body are rare and have the axis (fulcrum) located between the weight (resistance) and the force. One example is the joint between the head and the first vertebra.


In a second-class lever, the weight (resistance) is located between the axis (fulcrum) and the force. An example of a second-class lever in the human body is found in the lower leg when someone stands on tiptoes


In a third-class lever, the most common in the human body, force is applied between the resistance (weight) and the axis (fulcrum). There are numerous third-class levers in the human body; one example can be illustrated in the elbow joint.
