Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.
Answer:
b. Synergistic dominance
Explanation:
The stabilizing muscles will always be <u>synergistic</u>, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.
In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.
Septoplasty is the surgical procedure.
I would say about her body composition is that she is within recommendations for waist circumference and percent body fat. She has a normal BMI or Body Mass Index, she has a good body composition because she is a varsity player and she is exercising her body well. So the answer in this question is she is within recommendation for waist circumference and percent body fat.
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.
