Adaptations & Natural Selection
This type of adaptation involves actions or activities an organism performs to survive.
Behavioural Adaptation
This type of reproduction produces genetically identical offspring.
Asexual reproduction.
DNA is stored in this part of the cell.
Nucleus
How many daughter cells are created from mitosis?
2
A relationship between two organisms where both benefit is called this.
Mutualism
When a species becomes better suited to its environment over generations, this process has occurred.
Natural Selection
This type of gene needs two alleles in order to be shown.
Recessive.
A section of DNA that codes for a specific protein is called this.
Gene
This process produces four cells with half the number of chromosomes.
Meiosis
A species sensitive to environmental change is called this.
Bioindicator species
In order for two organisms to be classified as a species they have to meet two requirements. 1: they look similar. 2: _______________.
They can reproduce fertile offspring.
Choosing plants with desirable traits to reproduce is called this.
Artificial Selection
This structure is made of tightly coiled DNA strands.
Chromosome.
Tomato plants have 12 pairs of chromosomes. How many chromosomes would there be in the plant's gametes?
12
An organism’s role in its environment.
Niche
Who came up with the Theory of Natural Selection
Charles Darwin
The joining of a sperm and egg creates this.
Zygote
An organism whose DNA has been artificially altered by introducing genes from another species.
Transgenic
What types of cells use mitosis
somatic (body cells)
Aquariums exchange beluga whales mainly to increase this within populations.
Genetic variation.
When a species group gets separated and each group adapts to it's environment, eventually becoming two different species, this has occurred.
Speciation/ evolution
The female structure of a flower, consisting of ovary, style, and stigma, is called this.
Pistil
Which nitrogen base bonds with Thymine in DNA strands.
Adenine
This form of asexual reproduction is very similar to mitosis.
Binary Fission
When a species disappears from one area but still exists elsewhere, it is called this.
Extirpation
