Answers
Q1: Population
A: individuals of the same species living in the same area
Q2: Community
A: populations of all species living in one area
Q3: Ecosystem
A: all of the living and nonliving things in one area
Q4: Biosphere
A: all of the ecosystems on Earth
Q5: Biodiversity
A: differences or variation among living things
Q6: Gametes
A: haploid cells with only one copy of each chromosome (sperm and eggs)
Q7: Haploid
A: (n) n = the number of types of chromosomes in the cell
Q8: Diploid
A: (2n) n = the number of types of chromosomes in the cell
Q9: Fertilization
A: haploid gametes fuse to produce a diploid zygote
Q10: Mitosis
A: diploid somatic cells divide to make more diploid somatic cells
Q11: Embryogenesis
A: development of a functional embryo from a one-celled zygote
Q12: Differentiation
A: cells become specialized via a sequence of molecular events
, Q13: Morphogenesis
A: cells turn into an organized body plan
Q14: Cell phase G1
A: cell "growth", proteins for DNA replication are synthesized
Q15: Cell phase S
A: DNA is replicated/copied
Q16: Cell phase G2
A: cell "growth", preparation for cell division (centrosomes replicate)
Q17: Cell phase M
A: mitosis occurs (division of nucleus)
Q18: Centrosomes
A: these help move chromosomes during mitosis
Q19: Prophase
A: chromosomes condense, centrosomes begin to form mitotic spindle
Q20: Mitotic spindle (AKA spindle fibers)
A: system of protein microtubules that move chromosomes
Q21: Prometaphase
A: Mitotic spindle fully forms, microtubules attach to the chromosomes at a protein structure
called the kinetochore
Q22: Metaphase
A: microtubules align all the chromosomes at the equator of the cell.
Q23: Anaphase
A: Microtubules "pull" chromosomes to the ends of the cells, and push the ends of the cell
apart to elongate it.
Q24: Kinetochore microtubules
A: Attach to the chromosomes and move them.
Q25: Nonkinetochore microtubules
A: Attach to each other, elongate the cell during anaphase.
