A, b, and c! i’m sorry if you get this incorrect but i’m sure that it’s right
Answer:
The awnser is c. mucus good luck!
Explanation:
Answer:
Substitution
Explanation:
There are 3 types of mutations: deletions, insertions, and substitutions.
A deletion deletes one of the bases (AGTC), which can completely mess up the sequence and create a completely different protein.
An insertion inserts a new base into the strand, which can also completely mess up the sequence and create a completely different protein.
A substitution just changes one of the bases to a different base. This doesn't usually affect what protein is made, but when it does, it only changes one of the amino acids in the sequence, whereas the others change all of the amino acids in the sequence.
If the same protein is still created, then this person only experienced a substitution because it didn't affect the end result of the protein.
Species with more likely homologous structures share a common ancestor.
- D. share a common ancestor.
<h3>What are example homologous structures?</h3>
The most correct definition for homology would be: They are structures of individuals, of different species or not, that were inherited from a common ancestor. The human arm is homologous to the horse's front leg. The bat's wing is homologous to the whale fin.
With this information, we can conclude that homologous have same embryological origin of structures from different organisms, and these structures may or may not have the same function

What is a gene?
- According to Mendel something was being stably passed down, unchanged, from parent to offspring through the gametes, over successive generations. He called these things as ‘factors’ now called as genes. Genes, therefore, are the units of inheritance.
- They contain the information that is required to express a particular trait in an organism.
- Genes which code for a pair of contrasting traits are known as alleles, i.e., they are slightly different forms of the same gene.
- There is no ambiguity that the genes are located on the DNA, it is difficult to literally define a gene in terms of DNA sequence.
- The DNA sequence coding for tRNA or rRNA molecule also defines a gene. A cistron is defined as a segment of DNA coding for a polypeptide, the structural gene in a transcription unit could be said as monocistronic (mostly in eukaryotes) or polycistronic (mostly in bacteria or prokaryotes).
