The cells of multicellular organisms, like you and me, become specialized for particular tasks and communicate with one another

to maintain homeostasis. Cells, tissues and organs all help to maintain the organism's internal environment. But what about a unicellular organism? Does it maintain homeostasis? If yes, what part of the cell plays a part in this process? A) Yes, the DNA directs what happens inside the cell at all times. B) No. Because these cells live in water, internal balance is automatic. C) Yes, the cell membrane along with the nucleus helps maintain internal balance. D) No. Internal balance in unicellular organisms is based on osmosis of water into and out of the cell.

Predict the order of elution if you were to attempt to separate using column chromatography on silica gel and with a gradient el
Minchanka [31]

Answer:

Follows this order: B=> A => C.

Explanation:

NB: kindly check the attachment for the diagram of compounds A, B and C.

Elution is a very important concept in chromatography separation techniques. It deals with the use of eluent in the removal of an adsobate from an adsorbent. The principle behind Elution is just about how polar the solvent is.

So, in this question Compound B will go with the Elution first because of its polarity. Compound B has lesser polarity as compared to Compounds A and B.

Compound A will then elutes second because of its polarity too as resonance increases its polarity.

Last, compound C elutes because it has the highest polarity which is caused by electronegative atoms.

Who arranged the elements according to atomic mass and used the arrangement to predict the properties of missing element?
Marina CMI [18]

Answer:

Dmitri Mendeleev

Explanation:

Dmitri Mendeleev a Russian Chemist arranged elements on the periodic table according to their atomic mass. He used this arrangement to predict some of the properties of the missing element.

  • Dmitri Mendeleev around 1869 described the periodic table.
  • The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
  • In the Mendeleev table, elements are arranged by atomic weights with recurring properties in a periodic manner.
