Ecology
In an energy pyramid, the bottom level always contains these types of organisms.
What are autotrophs?
This cell organelle carries out a similar function as the human lungs by allowing oxygen in and carbon dioxide out of the cell.
What is the cell membrane?
This structure produces the male hormone responsible for sperm production.
What are the testes?
In order for a mutation to be inheritable, it must be present in these types of cells.
What are gametes?
One of the 2 processes that may result in genetic variation.
What are sexual reproduction and mutations.
This is a term for cutting down massive amounts of trees.
What is deforestation.
This process occurs when molecules move from a high concentration to a low concentration.
What is diffusion?
The organ that allows a fetus to get all the nutrients it needs for survival.
What is the placenta?
Name the type of alteration shown in the DNA below.
A-G-T-A-C-C-G-A-T --> A-G-T-G-A-T
What is a deletion?
As the environment changes, a change in the coloration of moths is noticed. This is an example of what Darwinian concept?
What is natural selection?
After ecological succession has occurred, this is the final community that will emerge and stay unless disrupted by something.
What is a climax community?
A person maintains this when they sweat.
What is homeostasis?
The process that turns a zygote into a ball of cells called a blastula.
What is mitosis?
The type of chemical used to cut and splice DNA.
What are restriction enzymes?
A word that means a trait that will help an organism survive.
What is an adaptation?
As the ozone shield diminishes, there is an increase in the amount of UV radiation on earth. Overexposure to UV radiation will result in what cellular change.
What is a mutation?
A pesticide that interferes with production of proteins in an insect will affect the activity of this organelle.
What is a ribosome?
A squirrel species has 40 chromosomes in each zygote. This is the number of chromosomes present in a liver cell.
What is 40?
The process used to separate DNA into different sized chunks.
What is gel electrophoresis?
A process in which a species passes out of existence.
What is extinction?
This is a type of organism that is introduced into an ecosystem that is not originally from that area and has no natural predators.
What is an invasive species?
The process that converts energy from the sun into chemical energy in the bonds of organic molecules.
What is photosynthesis?
The order of the following terms:
birth, mitosis, meiosis, fertilization
What is meiosis, fertilization, mitosis, birth?
This process can produce bacteria that produce a human protein.
What is genetic engineering?
If a rabbit has better eyesight than other of its species, this would happen to the frequency of this trait.
What is it would increase?
