Answer:
The correct answer is option c. "adaptive radiation".
Explanation:
The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.
The given statement is not true.
Biocentrism in an ecological and political sense, as well as, in an ethical perspective encompasses intrinsic value to all the living creatures. It is an understanding of how the earth functions, mainly as it associates with biodiversity.
The term biocentrism covers all the environmental ethics, which outspread the status of the moral object from human beings to all the living creatures in nature. Biocentrism witnesses each species as a component of the living biosphere.
It witnesses the outcomes of minimizing biodiversity on both the large and small scales and emphasis towards the innate values all the species exhibits towards the environment.
Answer:
A group of parasites called myxozoans have traditionally been considered simple multicellular protists. However, because these organisms possess stinging cells, some scientists consider them to be animals in the phylum that is named for such cells, the <u>cnidarians</u>.
Explanation:
Cnidarians are animals with radial symmetry, that is, their bodies can be divided, by different planes, into equal parts. It includes hydras, jellyfish, anemones and marine corals. Its body is a kind of sac with an opening (the mouth) surrounded by a circle of tentacles. Some have a dominant jellyfish phase, others polyp, or both. They present defensive nematocysts with stinging action.
