Meiosis and Mitosis
Type of cell division produces two identical daughter cells. Tissue and skin cells do this often
What is mitosis
This molecule holds all genetic information for the organism
what is DNA
this term describes all the living and nonliving things in an area
what is an ecosystem
this organelle is known as the "powerhouse of the cell"
what is the mitochondria
this is the basic unit of life
what is the cell
This type of cell division produces four genetically different cells. Only done by egg and sperm cells
What is meiosis?
this nitrogenous base is found in RNA but NOT in DNA
organisms that make their own food are called this
what is a producer
what is the cell membrane
this process allows organisms to maintain stable internal conditions
During this phase of mitosis, chromosomes line up in the middle of the cell
What is metaphase
What kind of mutation is this, substitution or deletion?
ACG TGA --> AGT GA
what is deletion
This is the role an organism plays in its environment
what is an ecological niche
this organelle helps with protein synthesis
what is the ribosome
this molecule is the main source of energy for cells
what is ATP
this process during meiosis increases genetic diversity by exchanging DNA between homologous chromosomes
What is the complementary DNA sequence to ATG CCA
What is TAC GGT
What type of symbiotic relationship benefits both organisms
what is mutualism
what is the main difference between prokaryotic and eukaryotic cells?
What is prokaryotic cells lack a nucleus and membrane-bound organelles, whereas Eukaryotic cells have them
This theory explains how species change over time through natural selection
what is evolution
what is one major difference between Meiosis I and Meisosi II
what is Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids
The process of copying DNA into RNA is called this
transcription
What is the difference between a food chain and food web
what is a food chain is a single pathway of energy flow, while a food web shows multiple interconnected pathways
this structure is found in plant cells and is used for photosynthesis
chloroplast
why is genetic variation important in populations?
what is it allows populations to adapt to environmental changes and increases survival chances
