Answer:

D) A Survey of fellow classmates

Explanation:

This is the correct answer because an informal survey involves various answers that may or may not be accurate.  Informal surveys cannot be held as scientific fact and are, therefore, not reliable. A scientific journal is reliable because it most likely includes data from an experiment and/or research of a trusted scientist or group. The results of past experiments are very reliable because these are the results of hard work and thorough planning and research. A scientific discussion with colleagues is not very credible because it involves the sharing of opinionated information, but it is certainly more reliable that the varying answers of school-aged peers.

Abiogenesis refers to how living organisms arose from inanimate matter. Place the sentences in order according to how life on Ea
horrorfan [7]

Answer:

(A) -> (D) -> (C) -> (B)

Explanation:

First off, given that the problem requires us to explain how life on Earth may have arisen <u>from terrestrial origins</u>, we can discard sentence (E), as impacts from meteorites would count as extraterrestrial origins.

Then it's just a matter of describing the steps by which simple compounds turned into more and more complex structures, that would in turn lead to the origin of life.

Simple inorganic compounds (such as CO₂, or NH₃) were exposed to energy, because of that they formed simple organic molecules, like carbohydrates or amino acids.

These organic molecules, in turn, would self-assemble into more complex structures, such as proteins.

Lastly, there's the phenomenon of Compartmentalization, where large organic structures became enclosed within a membrane-like structure, separating them from the 'outside' medium and thus creating primitive cells.

A selectively permeable membrane sac filled with water and large molecules of starch is suspended in a beaker of distilled water
madreJ [45]

A selective permeable membrane sac filled with water and large molecules of starch is suspended in a break of distilled water then water will enter into the sack and it will swell.

This is the process of osmosis in which movement of water molecules form a solution with high concentration to lower concentration till the equilibrium attain. Starch does not pass through thee selectively permeable membrane.Water moves from outside if the cell to the inside leading to swelling of cells.

Small molecules diffuse faster than larger molecules through a membrane. The movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute.
