Sustainability & The Science of Life
What are the three “legs” of sustainability?
Economic, environmental, and social balance.
Define ecology
Study of how organisms interact with each other and their environment.
What is a trait? Give two examples.
A trait is a characteristic that can be inherited. Examples: eye color, height.
What does DNA stand for?
Deoxyribonucleic Acid.
What happens during the interphase stage of the cell cycle?
Cell grows, copies DNA, prepares to divide.
What is conventional farming?
Uses synthetic fertilizers and GMOs.
What is a producer?
Makes own food; autotroph.
What does genotype mean? Give two examples.
Genotype is the genetic makeup (e.g., Bb, TT)
What is the shape of a DNA molecule?
Double helix.
What are the stages of mitosis (in order)?
Prophase, Metaphase, Anaphase, Telophase.
What are characteristics of life? List at least 4.
Cells, growth, reproduction, metabolism, homeostasis, response to stimuli, DNA, evolution.
What is a primary consumer?
Eats producers; herbivore.
Is BB dominant, recessive, or heterozygous?
BB is homozygous dominant.
What are the 3 parts of a nucleotide?
Sugar, phosphate, nitrogen base.
What is the function of mitosis in the body?
Growth, repair, replacement.
What is reproduction and why is it important?
Allows species to continue; offspring.
What biome has the most biodiversity?
Rainforest
What is selective breeding and why is it used in agriculture?
Selective breeding is choosing parents to pass on specific traits.
What does tRNA do?
Brings amino acids during translation.
How many cells are made during meiosis II?
4 cells.
Why is metabolism necessary for all living things?
Provides energy for life functions.
What is a biome? Give two examples.
Large ecosystem; examples: tundra, rainforest.
Explain how genotype affects phenotype.
Genotype determines which proteins are made, influencing traits.
Define transcription and state where it occurs.
Making RNA from DNA; in the nucleus.
What happens during the S-phase?
DNA replication.
