There is quite a bit of confusion in the industry. In computer science, most people loosely consider 1 Gb as 2^30=1073741824 bytes, while the prefix Giga actually means 10^9, or 1,000,000,000.
When we buy a hard disk, we are told (correctly) that it holds 1 Gb. Manufacturers base it on the mathematical definition of Giga and give you 10^9 bytes (less than 1073741824=1Gibibyte, or 1 GiB). This is standard practice in the disk drive industry. For example, a Windows 7 will show a 3 tera byte external disk as having 2.72 TB, or 3,000,557,891 byes, in which case it is actually assuming a TB to mean 2^40 byes (instead of TiB). That's where confusion lies.
Can something be done about it? Yes, it has been done since 2007. The less well-known, but official quantity for 1073741824 bytes is one GiB, proposed by the International Electrotechnical Commission (IEC), adopted by IEEE, EU, and NIST. Similarly, 1 TiB means 2^40=1,099,511,627,776 bytes. The prefixes have been replaced by bi (for binary), so Kibibyte, Mebibyte, Gibibyte, Tebibyte, etc.are used to represent 2^10, 2^20, 2^30, 2^40 bytes. Unfortunately I have yet to see this widely being used, or even known!
The process of <span>surrounding and engulfing of food particles </span>is defined as phagocytosis in biology. One of the protists where phagocytosis takes place are amoeba.Protists are not true animals, plants, not fungi. However this form of feeding are exhibited like animals. Answer is C.
