1.
What is an example of a kingdom?
Correct Answer
A. Animal
Explanation
An example of a kingdom is animal because the kingdom Animalia includes all multicellular organisms that are eukaryotic and heterotrophic. Animals are characterized by their ability to move, their lack of cell walls, and their ability to ingest food. This kingdom includes a wide variety of organisms such as mammals, birds, reptiles, fish, and insects.
2.
Which of the following options are true regarding Algae?
Correct Answer(s)
A. Contains chloropHyll
B. Lacks stems, roots, leaves, and vascular tissue
E. Non-Flowering
Explanation
Algae are photosynthetic organisms that contain chlorophyll, enabling them to convert sunlight into energy. They lack stems, roots, leaves, and vascular tissue, which are characteristic features of higher plants. Instead, they have simple structures like thalli or filaments. Algae can be single-celled or multicellular, but many species are indeed single-celled. They are autotrophic, meaning they produce their own food through photosynthesis, and are therefore not heterotrophic. Additionally, algae are non-flowering, as they do not produce flowers or seeds for reproduction.
3.
Which of the following options are true regarding Amoebas?
Correct Answer(s)
B. Single-celled organism
C. Freshwater organism
D. No mouths
Explanation
Amoebas are true regarding being single-celled organisms, as they consist of a single cell that performs all necessary functions. They are also true regarding being freshwater organisms, as they are commonly found in freshwater environments such as lakes and ponds. Additionally, amoebas do not have mouths, as they capture and engulf their food using pseudopods.
4.
Which of the following options are true about Parameciums?
Correct Answer
F. All the above
Explanation
Parameciums are single-celled organisms that are free-living protozoans. They are shaped like a shoe sole and have cilia, which are hair-like structures that help them move. Additionally, Parameciums are heterotrophic, meaning they obtain their nutrition by consuming other organisms. Therefore, all of the given options are true about Parameciums.
5.
Which options are true regarding Autotrophic?
Correct Answer(s)
A. Grass
C. Rose
D. Algae
Explanation
The options that are true regarding autotrophic organisms are grass, rose, and algae. Autotrophic organisms are capable of producing their own food through the process of photosynthesis. Grass, rose, and algae are all examples of autotrophs as they have the ability to convert sunlight into energy and synthesize organic molecules such as glucose. Birds, on the other hand, are heterotrophic organisms that rely on consuming other organisms for their energy and nutrients.
6.
There is _____________ Bacteria in a gram of soil.
Correct Answer
A. 40 million
Explanation
The given answer states that there are 40 million bacteria in a gram of soil. This suggests that the soil contains a significant amount of bacteria. It is important to note that this answer is specific and provides a quantitative measurement, indicating a relatively high concentration of bacteria in the soil sample.
7.
What is the science of classifying and naming organisms called?
Correct Answer
D. Taxonomy
Explanation
Taxonomy is the science of classifying and naming organisms. It involves organizing and categorizing living organisms based on their characteristics and evolutionary relationships. This helps scientists understand the diversity of life and how different species are related to each other. Taxonomy also involves assigning scientific names to organisms, which allows for clear communication and avoids confusion caused by common names. Therefore, taxonomy is the correct answer to the question.
8.
What is the largest taxon group?
Correct Answer
B. Domain
Explanation
The largest taxon group is the domain. Taxonomy is the science of classifying organisms into different groups based on their characteristics and evolutionary relationships. The domain is the highest level of classification, encompassing multiple kingdoms. It is larger than the kingdom, phylum, and species, as it includes a broader range of organisms that share certain fundamental characteristics.
9.
What is the smallest taxon group?
Correct Answer
A. Species
Explanation
The smallest taxon group is species. Taxonomy is the science of classifying living organisms into different groups based on their characteristics and evolutionary relationships. The hierarchy of taxonomic groups starts with domain, followed by kingdom, phylum, class, order, family, genus, and species. Species is the most specific and smallest taxonomic group, consisting of individuals that share similar characteristics and can interbreed to produce fertile offspring.
10.
What does Binomial Nomenclature mean?
Correct Answer
A. Two terms are used to denote a specie
Explanation
Binomial nomenclature refers to the naming system used in biology, where two terms are used to denote a species. This system was developed by Carl Linnaeus to provide a standardized way of naming and classifying organisms. The first term represents the genus, while the second term represents the species. This naming convention helps to ensure clarity and consistency in identifying and categorizing different species.
