How does the understanding of genotype and phenotype contribute to the study of heredity?
How does the understanding of genotype and phenotype contribute to the study of heredity?
- By predicting the exact physical traits based solely on environmental factors.
- By eliminating any influence of environmental factors on inherited traits.
- By isolating genetic traits ensuring complete predictability of offspring traits.
- By determining the expressed traits influenced by genetic makeup and environmental factors. (correct)
Which of the following is an example of how biotic and abiotic factors interact within an ecosystem?
Which of the following is an example of how biotic and abiotic factors interact within an ecosystem?
- A flood drastically changing a river's ecosystem.
- Decomposers breaking down dead organic matter.
- Plants converting sunlight into energy (photosynthesis). (correct)
- Predators hunting prey within a forest.
How do food chains and food webs relate to each other in an ecosystem?
How do food chains and food webs relate to each other in an ecosystem?
- Food chains are independent of food webs, showcasing different trophic levels.
- Food chains and food webs are two unrelated concepts in ecological studies.
- Food chains represent complex feeding relationships, while food webs show simple linear chains.
- Food webs are a collection of interconnected food chains representing the flow of energy. (correct)

Flashcards
Digestive System
Digestive System
The organ system responsible for breaking down food and absorbing nutrients.
Cell Cycle
Cell Cycle
The series of events that lead to cell division and duplication (replication).
Mitosis
Mitosis
Cell division that results in two daughter cells each having the same number of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Meiosis
Meiosis
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell.
