A group of organisms that live in the same area and interact with each other and their environment.
What is a community?
This type of reaction can form a bond between two monomers.
What is dehydration synthesis?
This organelle is only found in eukaryotes, and contains the cell's genetic material.
What is the nucleus?
______ must be consistently resupplied to an ecosystem, as it is continuously lost as heat and cannot be recycled.
What is energy?
Labeled "1" in the diagram, these intermolecular forces give rise to the many unique properties of water.
What are hydrogen bonds?
The maximum population of an organism that an ecosystem can support.
What is the carrying capacity?
Starch, which is a polymer of glucose, is an example of this type of macromolecule that only includes the elements C, H, and O.
What is a carbohydrate?
These organelles produce proteins.
What are ribosomes?
This rule helps to explain why food pyramids don't contain more than five trophic levels.
What is the 10% rule?
This property of water allows insects to be able to glide across a pond, or for a large number of drops to stack on a penny.
What is its high surface tension?
One example of this relationship occurs in the relationship between a remora fish and a shark, where the remora attaches itself to the shark and eats scraps of food left behind by the shark's feeding, benefiting from the shark's presence without harming it, while the shark is essentially unaffected by the remora's presence.
What is commensalism?
Examples of these biomolecules include cholesterol and triglycerides.
What are lipids?
One piece of evidence for this theory is that mitochondria and chloroplasts have their own DNA.
What is endosymbiont theory?
The cycle of this element does not include an atmospheric component.
What is phosphorus?
This functional group is acidic.
What is a carboxyl group (carboxylic acid)?
One example of this type of population-limiting factor is a disease that spreads more easily when the population is high.
This nucleotide is only found in RNA.
What is uracil (U)?
In this type of cell transport, water is transferred from an area of low solute concentration to an area of high solute concentration?
What is osmosis?
One step in this process involves a dramatic increase in the amount of decomposers present, due to an excess of nitrogen, that ultimately leads to the death of fish and other aquatic organisms.
What is eutrophication?
This functional group is the only one we studied that is nonpolar.
What is a methyl group?
Eagles produce just a few offspring and spend significant resources in their care. Eagles also have fairly stable populations and have evolved to better compete for limited resources. They are an example of this type of population selection.
What is K-type selection?
These are held together by hydrogen bonds between non-adjacent amino acids in the polypeptide backbone.
What are protein secondary structures?
This process occurs when a cell creates a vesicle from its own membrane to import a substance from the outside.
What is endocytosis?
The cycle of this element depends on bacteria that can "fix" the element from the atmosphere, making it available to other organisms.
What is nitrogen?
The basic properties of this functional group can lead it to be positively charged.
What is an amino group?
