Answer:
Challenge : Competition form other species.
Success : Adaptation and colonisation.
Explanation:
- Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge.
- Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.
The correct answer in the space provided is bodily changes. It is because when a clinician is in the field of thanatology, it is likely that he or she is focusing on the aspects of death in which he or she investigates forensically, changes in the body or the post mortem period that is associated to death.
Complete question:
Which of the following pairs represent homologous structures?
- Wings of grasshopper and forelimbs of flying squirrel
-
Tentacles of Hydra and arms of starfish
-
Forelimbs of a bat and forelegs of a horse
-
Wings of a bird and wings of a moth
Answer:
3. Forelimbs of a bat and forelegs of a horse
Explanation:
Homologous characters are structures with the same basic elements. Their position in the body and the relations with adjacent structures are also the same in different organisms, and they even share the same embryological development.
These structures might show variations between the organisms exhibiting them. Variations might be related to their function and to the environment in which the organism lives. The function they accomplish is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
For example, whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development.
Among the options, the only possible pair that represents homologous characters is option <em>3. Forelimbs of a bat and forelegs of a horse</em>. Both structures are the anterior extremities of the animals and share the same bones, even though they might differ in the development degree. Forelimbs and forelegs have the same position and relation with other structures in the body, and embryologically, they are the same.
