Which of the following describes the inheritance of traits from parents to offspring?
Adaptation
Evolution
Natural selection
Genetics
Correct answer is D
Genetics is the field of biology that studies the inheritance of traits from parents to offspring. Genetics encompasses various concepts and principles, including the study of genes, DNA, chromosomes, genetic inheritance patterns, genetic mutations, and genetic variations.
Which of the following is the most inclusive level of classification in the Linnaean system?
Kingdom
Phylum
Domain
Class

Viviparity refers to the reproductive strategy in which
Offspring are produced by internal fertilization
Offspring are produced by external fertilization
Offspring develop and are nourished inside the female's body
Offspring develop and are nourished outside the female's body
Correct answer is C
Viviparity is a reproductive strategy in which offspring develop and are nourished inside the female's body until they are ready to be born. Viviparity is commonly observed in various organisms, including mammals, some reptiles, and certain fish species. In viviparous species, the developing offspring receive nutrients and oxygen directly from the mother through specialized structures such as a placenta or other nutrient-transfer organs.
Which of the following statements is true about the kingdom Fungi?
Fungi obtain nutrients by absorbing organic matter
Fungi are photosynthetic organisms
Fungi are multicellular organisms
Fungi reproduce through the formation of seeds
Correct answer is A
The correct statement about the kingdom Fungi is that fungi obtain nutrients by absorbing organic matter. Fungi are heterotrophic organisms, meaning they cannot synthesize their own organic compounds. Instead, they secrete enzymes to break down organic matter in their surroundings, such as decaying plants or dead animals, and absorb the resulting nutrients.
Which of the following is NOT a method of reproduction in animals?
Asexual reproduction
Budding
Sexual reproduction
Sporulation
Correct answer is D
Sporulation is a method of reproduction observed in some groups of organisms, such as fungi and certain types of protists. It involves the formation and release of spores, which are specialized reproductive structures that can develop into new individuals under suitable conditions. Sporulation is not a method of reproduction in animals.
