Cells
The organelle present in all cells.
What is cell membrane
A collection of organs working together to perform a specific function in a living organism.
What is an organ system
This system works with the circulatory system to deliver oxygen to the body and remove carbon dioxide.
What is the respiratory system
An organism has one dominant and one recessive allele for a trait. What is its genotype?
What is heterozygous
This principle states that individuals with traits best suited to the environment are more likely to survive and reproduce.
What is survival of the fittest
The part of a plant cell that stores water and helps maintain its shape
What is the central vacuole
The highest level of cellular organization.
What is organism
This body system protects internal organs and helps with movement by attaching to muscles.
What is the skeletal system
The physical expression of a trait, such as brown eyes or curly hair
What is a phenotype
Due to climate change, a bird species' food source shifts from soft berries to hard-shelled nuts. Birds with which trait are likely to thrive?
A) Long, thin beaks
B) Strong, thick beaks
C) Bright feathers
D) Webbed feet
What is B strong, thick beaks
Which organelle stores genetic information?
What is the nucleus
The human heart is made of muscle tissue, connective tissue, and nerve tissue. What level of organization does this represent?
What is an organ
What is the largest human organ?
What is the skin
Describe the relationship between DNA, genes, and chromosomes.
Genes are segments of DNA, and chromosomes are long strands of DNA containing many genes
A population of beetles lives in a forest with many birds that eat insects. The beetles come in green, brown, and bright blue. Over time, the bright blue beetles become rare. Which trait likely improves survival?
What is Green or brown coloration
This is the semi-fluid substance inside the cell that contains all organelles.
What is cytoplasm?
The type of tissue in animals that contracts to allow movement.
What is muscle tissue?
What are the main organs of the integumentary system?
What is hair, nails, and glands
A dog with black fur (B) and a dog with white fur (b) produce all black puppies. What are the parents’ genotypes?
What is BB and bb
In a species of bird, chicks that are too small often struggle to compete for food and may not survive. Chicks that are too large are more likely to break their eggshell too early and die before hatching. Over time, medium-sized chicks become the most common. What type of natural selection is most likely occurring?
What is stabilizing selection
Compare the functions of chloroplasts and mitochondria in energy conversion.
What is chloroplasts convert solar energy to chemical energy (glucose), mitochondria convert glucose to ATP?
Skin cells work together to form a barrier that protects the body from pathogens and dehydration. What level of organization does this represent?
What is a tissue?
How do the circulatory and digestive systems interact after a meal?
The digestive system absorbs nutrients, which the circulatory system delivers to cells
What is the probability of a heterozygous offspring if the parents are homozygous dominant round and heterozygous round?
What is 50%
Explain how the beak lab completed in class demonstrated natural selection.
Different beak shapes adapted based on available food sources on each island.
