e. spores
Explanation:
In the given question, the characteristics of a plant are mentioned which are the dominant sporophyte, cell wall and the Chl a or b.
It is mentioned that the plant has a dominant sporophyte therefore it produces the spores during its life cycle. The other features like the endosperm, seeds, flowers are the characteristics on the basis of which the plant can be characterised as they differ in the plants.
Since the production of spores is a characteristic feature of the sporophyte, therefore, it will be least considered by the botanist to discover a new species.
Thus, Option-E is the correct answer.
Answer:
The Grants's research shows that variation within species increases the likelihood of the species' adapting to and surviving the environmental change.
Explanation:
The beaks of individual birds can change depending on what food is available.
Over time, individuals can evolve to better fit the environment by changing heritable traits.
Beak depth and length must affect survival and/or reproduction of birds.
Beak depth and length must be heritable.
Beak depth and length must show variation among individuals of a single species.
Glassy igneous rocks (i.e. obsidian) are cooled very rapidly.
A. there is a change in Genetic frequency
