What is the structure of DNA?
A double helix
After meiosis, how many daughter cells result?
four haploid daughter cells
What is heredity?
the passing of genes from one's parents to offspring
The process of storing light energy in chemical bonds:
Photosynthesis
Individuals best suited to compete, survive, and reproduce in their environment will pass on favorable traits.
What is Natural Selection?
What are the four Nitrogen bases of DNA?
Adenine, Thymine, Guanine, and Cytosine What are the four Nitrogen bases of DNA?
Why is mitosis necessary?
Growth, development, repair
Blood tying
It is a secondary or tertiary consumer, it eats only other animals.
What is a carnivore
This evidence of evolution demonstrates the similarities in early development of embryos
What is embryology?
What does mRNA do?
It travels from the nucleus to the ribosome to give the codes to make proteins
What is fertilization?
Process in sexual reproduction in which male and female reproductive cells join to form a zygote
What is a carrier?
a heterozygous individual that has a recessive allele of a gene but expresses their dominant allele
When organisms occupy the same niche this occurs
Competition
Nature provides the variation and humans select the variations they find most useful (examples include dog breeds)
What is artificial selection?
Why is RNA necessary to act as a messenger? Why can't the code be taken directly from the DNA?
RNA acts like a messenger because it transfers the sequence for one Gene on the DNA strand; DNA must remain in the nucleus
How does meiosis contribute to genetic variation?
In a cross between two heterozygous parents, what percentage of their offspring is expected to have the recessive trait?
25%
It is a relationship in which one of the species involved benefits and the other is neither helped nor harmed.
Commensalism
The reason behind why finches have differently shaped beaks on different islands
What is genetic variation leading to adaptation?
One side of a DNA strand is coded AGTCAGGATTC, what is the other side of the DNA strand?
TCAGTCCTAAG
What is uncontrolled cell division called? What causes it?
In addition to genetics, what other factors can influence how an organism grows and develops?
Environmental factors
What is the stable ecosystem that develops due to succession?
Climax Community
What is the most compelling evidence that demonstrates evolutionary relationships?
What are DNA Sequences/Protein Sequences?
