It is assumed that organisms with similar anatomical characteristics have evolved relatively recently and have a common ancestor.
<h3>How does comparing the physical characteristics of different creatures help us understand evolution?</h3>
To comprehend how living things originated, scientists study the anatomy, embryos, and DNA of various species. Homological structures provide proof of evolution. These are features that were passed down from a common ancestor and are shared by related creatures. An further piece of evidence for evolution is offered by similar structures.
<h3>What role does anatomy play in the study of relationships between various types of organisms?</h3>
Comparative anatomy, which compares structural similarities, is one of the strongest types of evidence of creatures to ascertain the links between them throughout evolution. It is assumed that organisms with similar anatomical traits have evolved from ancestors who were reasonably closely connected to one another.

The answer is D interphase
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
The experiment is to prove that the semiconservative model is more accurate than the dispersive model of DNA replication
<h3>What is DNA replication?</h3>
DNA replication is the process where new copies of DNA are made from existing DNA copies.
DNA replication was suggested to occur in two ways:
- The semiconservative model
- the dispersive mode
The Semiconservative replication produces two helices, each containing one old strand and one new strand
The Dispersive replication produces two helices in which each strand contains alternating segments of old and new DNA.
The semiconservative model is the accepted model because it produces more accurate copies by ensuring continuous replication in the replication mechanism.
Therefore, the experiment is to prove that the semiconservative model is more accurate than the dispersive model of DNA replication.
