23
22 The method proposed by Charles Darwin to explain the process of evolution is termed: Coevolution Natural Selection Principle of population Spontaneous Generation
24
Meiosis results in the formation of:
23 Meiosis results in the formation of: Cells with a haploid number of chromosomes Cells with a diploid number of Cells with the same number of chromosomes as the parent cells d. Cells with only 1 chromosome
25
24 What does the fossil record show about the history of species on Earth? Species stay the same over time. Species evolve from one form to another. Modern species have no relationship to ancient species No new species have emerged in the last 200 million years.
26

27
In this process, cells use glucose to produce energy:
26 In this process, cells use glucose to produce energy: Photosynthesis Homeostasis Respiration Lysosome
28
Why do some strains of bacteria become resistant to antibiotics?
27 Why do some strains of bacteria become resistant to antibiotics? The bacteria develop a method of surviving without energy. Through natural selection, some bacteria develop an adaptation that enables them to survive in the presence of antibiotics The bacteria grow in habitats protected from antibiotics Bacteria that live in host organisms are not affected by antibiotics.

30
What is the purpose of transfer RNA (tRNA)?
29 What is the purpose of transfer RNA (tRNA)? It unzips the double helix so transcription can begin It retrieves amino acids from the cytoplasm for protein construction It carries genetic information to the ribosomes It produces a complementary copy of a strand of DNA
31
What form of energy is used by cells?
30 What form of energy is used by cells? ATP DNA Enzymes ABC
32

The barn owl population will increase The mouse population will decrease The barn owl population will decrease The mouse population will remain the same
33
