The question is incomplete as it does not have the options which are:
A) eight legs.
B) two pairs of antennae.
C) a sessile lifestyle.
D) an open circulatory system.
E) parapodia.
Answer:
D) an open circulatory system.
Explanation:
In the given question, the characteristics of an organism are given which are:
1. Exoskeleton- outer covering composed of cuticle
2. system of tubes for gas exchange- do not respire but has tubes called trachea from which the air diffuses
3. modified segmentation- segmented bodies
All these characteristics show that the organism belongs to the Arthropods group of animals.
The Arthropods since having trachea for the diffusion of gas, therefore, possess an open circulatory system in which blood does not flow in the vessels but the open cavities in the body.
Thus, Option-D is the correct answer.
Answer:
The correct answer is "a large-scale natural system such the Great Lakes".
Explanation:
Mathematical models are used in scientific investigations to study complex systems. This applies to the study of ecosystem dynamics of large-scale natural systems such as the Great Lakes. The Great Lakes comprise five lakes that in conjunction are 244,106 km2 long, with a complex ecosystem that includes invasive species, climate change, pollution, among other factors. It will be very complicated to study the ecosystem of such a large habitat without using mathematical models.
