Answer:
b. Phylogenetic speciation
Explanation:
Autapomorphies are molecular or morphological traits found in a unique taxon. An autapomorphy is not found in outgroup and therefore these traits are used to classify a group into a category (i.e., species, genera, family, etc)
Fats and lipids are hydrophobic which makes them water repelling compounds. Therefore, presence of a waxy coating on the outer skin of the desert plant prevents loss of water via evaporation from the skin of the plants. This helps the plant store water and increases its survival period.
The answer is; 1
Most of the photosynthetic organisms are located in the epipelagic zone of the oceans where sunlight can penetrate before diffusing and becoming too weak to support photosynthesis. The epipelagic zone is filled with plankton. When this plantkon die, they begin to sink slowly to the bottom of the ocean. These plankton are food for small fish. These small fish are food for bigger fishes. This is how an ecosystem is sustained in the deep dark oceans.
Answer:
Dandelions may appear <u>quicker after harsh conditions and reproduce at a faster rate.</u> However, both dandelions and shrubs are considered <u>fast-growing plant species</u> that can be categorized as <u>pioneer species.</u>
Explanation:
Secondary succession refers to the changes that take place in a disturbed habitat. Pioneer plant species are those that <u>colonize new habitats after harsh climate conditions and that tend to reproduce at a fast rate.</u>
According to researcher J.W. Darlling (2008), pioneer herbs and shrubs are species that tend to grow faster in comparison to other species, making them excellent pioneer species.
This occurs thanks to plants that are <u>wind-pollinated</u>, such as dandelions, have a higher chance to appear because, as it is a disturbed environment, there are no insects or other fauna present. In addition, shrubs are <u>persistent species that are able to reproduce fast with limited soil availability</u> but a bit <em>slower</em> in comparison to dandelions.
