What are similar structures that evolved independently called?

Biology
1 answer:
Ilia_Sergeevich [38]3 years ago
4 0

Answer:

Analogous structures

Explanation:

These structures are similar but not derived from the common ancestor like homologous structures. Analogous structures are formed as a result of convergent evolution-type of evolution in which organisms develop on similar way but independently. An example of analogous structures are wings. Birds, insects and bats all have wings, with the same purpose (flight) but they evolved in their own way.

lyudmila [28]

Answer:

Sam, Tim, Bella, and Joshua

Explanation:

The correct answer would be <em>Sam, Tim, Bella, and Joshua</em>.

<u>The human pedigree is a pictorial representation of a family tree that depicts how a particular trait is inherited across different generations.</u>

In the human pedigree, those phenotypically affected for the trait in question are represented by filled-in shapes, with circles representing females and squares representing males. Half-filled shapes represent heterozygosity or carriers of the trait.

<em>Sam, Tim, Bella, and Joshua were represented by filled-in shapes in the illustrated pedigree. Hence, they are affected for red-green color blindness. </em>

_______ cause(s) populations to change over time.
vekshin1
The answer is B., Natural Selection.

Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.

So, the only answer left is natural selection, and it makes sense too! 
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.

Each of the proteins involved in DNA replication plays an important role. If one of these proteins was not functional it would h
Masteriza [31]

Answer:

Explanation:

1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..

2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.  

3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.  

4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.  

5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.  

6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.
