Answer:
The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"
Explanation:
The fruit fly <em>Drosophila melanogaster</em> is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.
Answer:
A
Explanation:
I think its A but it can also be made to condense into a liquid
A, because, the entire point of his theory was to prove that changes don't happen spotaneously!
Adaptive immunity is based upon the interactions between specific immune system cells and a specific antigen. This happens when cell surface of B cell binds to antigen thus lead to activating B cells. Hope this is the answer and this would help.
