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:
The three different types of pteridophytes include:
Ferns.
Horsetails.
Lycophytes.
Explanation:
Answer:
Yes, competition is likely to occur
Explanation:
Competition is an ecological interaction between organisms of the same or different species, resulting in the detriment of one of the organisms. Competition is generally caused when organisms in an ecosystem occupies the same niche i.e. they rely on the same ecological resource, which could be food, mate, space etc.
The case described in this question involving a Bagheera kiplingi (jumping spider) and acacia ants will likely result in competition because they both occupy the same habitat and feed on the same food (vegetable plant). The two organisms will have to compete for this limited resource, hence, it is regarded as an INTERSPECIFIC COMPETITION because it involves two different organisms.
Out of the choices given, the following bacterial cells that would be best able to survive an attack by an antibiotic is; A bacterial cell that has a cell membrane made of ester-linked fatty acids. The correct answer is B.
