Because they were passed down from a common ancestor, homologous structures are those found in related organisms that are comparable. These structures might or might not serve the same purpose in their offspring. The hands of various different mammals are depicted in the figure below. The basic skeletal structure of each is the same.
What is offsrping?
a person, animal, or plant's offspring or progeny is the result of reproduction. Parental transmission of the illness can affect children, a human or animal's direct offspring; a person born of parents gave birth to a lone child.
Creating offspring is considered reproduction. Reproduction comes in two basic forms: sexual reproduction and asexual reproduction. A sexually reproducing creature integrates the genetic material of both parents to create a genetically distinct individual. Asexual reproduction involves the self-replication of one parent to create genetically identical kids.

Answer:
Some substance in the infectious S strain could change the harmless R strain into the more lethal form.
Explanation:
These first type of experiments where crucial to advance in DNA knowledge.
In one experiment, they treated the material with enzymes that destroy all proteins. This is important because scientist notice that there was something else that was causing the strain to change into a lethal form and was heritable (DNA). Know a days we know that plasmids are responsible for such transformation.
Answer:
Its either B or C but I would go with C
Explanation:
Answer:
A: yes
Explanation:
B: Sample three is a mixture of the suspect and victims. Putting it simply, if you line up the victims DNA and remove it from sample 2 you are left with a sample of DNA that is identical to the suspects.
Answer: B. Nuclear transfer!
Explanation:
Nuclear transfer is the process that DNA goes through to get cloned/copied. The cells that make new forms of DNA create a perfect replica.
Hope this answer helps!
