It can be observed from their compositions that methyl orange is a polar compound because of the existence of -SO3Na functional group. The -SO3Na group is ionic in nature and imparts polarity to methyl orange. While biphenyl is a non-polar compound because of the non-existence of polar functional groups in its composition.
The silica gel chromatography refers to an apparatus, which is used to distinguish molecules on the basis of their polarity variations. The silica gel, that is, a stationary phase is polar in nature, and thus, the non-polar compounds seem to elute prior to the polar ones.
In the mentioned case, the biphenyl will elute first because of its non-polar characteristic and thus will exhibit high Rf value.
The cell membrane.
Hope it helps!
Answer:
Ang parehong mga mapagkukunan ay nagbibigay ng impormasyon.
Paliwanag:
Kailangan nating suriin nang mabuti ang pinagsamang pangunahin at pangalawang mapagkukunan dahil ang parehong pangunahing at pangalawang mapagkukunan ay nagbibigay sa amin ng impormasyon tungkol sa mga tuklas o mga kaganapan na naganap sa nakaraan. Ang pangunahing mapagkukunan ay nagbibigay ng ulat o orihinal na pag-iisip tungkol sa mga kaganapan o tuklas samantalang ang pangalawang mapagkukunan ay nagbibigay ng pagtatasa at interpretasyon tungkol sa pangunahing mapagkukunan kaya't ang parehong mga mapagkukunan ay nagbibigay ng impormasyon tungkol sa isang kaganapan.
The correct answer is option E
The kingdom Protista includes large diversity of organisms ranging from flagellated cells to macroscopic organisms. It is sometime referred as Protoctista instead of Protista. Some of the ancient Protista’s have characteristics of animal and plant kingdom. For example Lichen is not a protist but it includes the characteristics of both Protista and Fungi. Likewise organisms such as algae, bacteria, ciliates have the features of Protist as all these are Eukaryotic cells. Since the formation of kingdom Protista many animals have been included and excluded from the kingdom. Even today red and brown algae are considered as protist
