The purpose of a dichotomous key is to identify organisms
Explanation:
A dichotomous key is a kind of a tool that guides to classify and identify different organisms.
This key as the name indicates - dichotomous- consists of two parts or options to identify a species.
The method utilizes a series of questions/answers with two possible outcomes.
Taxonomically, a dichotomous key is used to basically identify a species or an organism by its scientific name.
All of the natural elements like the plants, animals, birds, etc are identified using this key.
Types of dichotomous key includes nested, linked, branching tree etc.
The correct answer is d) kingdom.
Taxonomy is the branch of biology which deals in categorizing and naming of species. The modern taxonomic classification system consists of the eight taxonomic groups. These are Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. The domain is the most inclusive of the all taxonomic groups and species is the least inclusive. It is because every different species has a unique features. In this question domain is not in the option, thus Kingdom is the correct answer As it includes different Phylum, Class, Order, Family, Genus, and Species.
Answer:
The question is incomplete as there are no options, the options are:
What would be the next step in this experiment?
A. construct a hypothesis and record data
B. make observations and draw a conclusion
C. ask questions and construct a hypothesis
D. analyze the results and make a conclusion
The answer is D
Explanation:
According to this question, a student performs an experiment where she places apple fruit on one location and places apple and banana together in another location. She follows the steps of the scientific method in performing this experiment.
The steps involved in the scientific method include:
- Making an observation
- Constructing an hypothesis
- Testing the hypothesis (experimentation)
- Analyse the result
- Draw a conclusion
The student in this question has already made the observation that when bananas are kept near other fruits, the other fruits ripen faster. She has hypothesized that bananas must have an influence on the ripening process. She tests the hypothesis via an experiment described above. Hence, the next step is to ANALYZE THE RESULTS she will get after 5 days and DRAW A CONCLUSION based on that.
