Yes, air has weight.
Air has weight, although at a slightly lower density than something more tangible, like water.
We don't feel that the air has weight because the air moves in all directions, so we get "squished by the air" by a miniscule amount

Air does have weight. 14.7 psi in fact. Most of the air is Nitrogen gas, which is 2 atoms of nitrogen. There is also Oxygen gas (O2). Finally there is Carbon Dioxide (CO2). There is also a small percentage of other gasses, but they are insignificant.

Snezhnost [94]

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.
