Answer:
The answer is A) Homologous structures
Explanation:
Homologous Structures:
- Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
- Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
- For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.
- Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
- Inherited and developmental are out of context in terms of evolutionary relationships.
C would be the correct answer because The glacial budget refers to the balance between the amount of inputs versus outputs affecting the glacial system. So the glacier loses mass as evaporation will increase due to warmer temperatures and there will be melting at the snout. This part of a glacier is known as the zone of ablation.
<u>Answer:</u>
<em>Predator-prey and herbivore-plant relationships are crucial in shaping communities. </em>
<u>Explanation:</u>
<em>It is the predator species in area that checks the number of prey species in a certain geographical area.</em> More the number of predator species in an area less is the number of prey species in the area.
Similarly the geographical location of preys will depend on the geographical location of predators. <em>Preys tend to flee away from the location of predators. Plant-herbivore relation is also similar.</em>
The number of herbivores checks the number of plants in an area. In the absence of herbivores and predators the <em>number of prey species and plants will exceed beyond limit. </em>
No, not really - you just follow the method, that's it.
