Tran made the timeline below to show the order in which great scientific theories were developed. theory of gravity à cell theory à ? À theory of continental drift Which theory belongs in place of the question mark in Tran's timeline? Aristotle's atomic theory Newton's laws of motion Copernicus's heliocentric theory Darwin's theory of natural selection

The correct option is;

Darwin's theory of natural selection

Explanation:

(A) The theory of gravity was introduced Sir Isaac Newton in the published work of Philosophiae Naturalis Principia Mathematica which consisted of three books on the 5th of July 1687

(B) In 1839, and 1858,  Theodor Schwann and Rudolf Virchow, respectively proposed the cell theory which consisted three parts viz

1) Cells are the building blocks of organisms

2) The cell is the fundamental life unit

3) Cells come from other preexisting cells

The first two parts was proposed by Theodor Schwann in 1839, while the third part was proposed by Rudolf Virchow, in 1858

(C) In 1859, Charles Darwin proposed the theory of natural selection in his book the "On the Origin of Species" which is the process by which an organism change so as to survive ad reproduce in its environment

(D) In 1912, Alfred Wegener, proposed the theory of continental drift.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

thats a little if u want the answer just look it up on google thats what i do haha : )
