The horsehair worm is aquatic, but the cricket is terrestrial.
An adult horsehair worm emerges as the cricket drowns.
The spider stops building its normal orb-shaped web and starts building a web that is strikingly different: The new web is designed to suspend the larva's cocoon in the air, where it will be protected from predators.
The life cycle of Toxoplasma gondii involves more than one host.
The cat is where gondii becomes mature and reproduces sexually.
An intermediate rats host can be any of a variety of animals, including mice and rats, which can ingest the parasites from cat feces.
To escape an intermediate host, such as a mouse or rat, and move to the definitive host, T. gondii dramatically alters the host's behavior.
It is more likely to be eaten by a cat.
Future biologists will make important advances.
Biologists look for answers to control the host's behavior.
The work of unraveling these mysteries presents has exciting challenges for the best and brightest minds.
The study of how a career in biology involves forging into parasites that control the nervous systems of their hosts.
Researchers have discovered many examples of and lives of people, and the satisfaction of trying to preserve the zombie parasites, because of the thrill of making discoveries that can improve the health past few decades.
These are some of the many discoveries that make biology appealing to students.
The study of life shows rewarding careers and the desire to choose biology as a lifelong pursuit.
Section 1.3 has a question about depth.
When making new discoveries, the scientists follow.
A cell is thinking about how life is organized.
Organisms are composed of one cell and multicellular rated from the environment.
Plants and animals have a lot of cells.
All matter is made of atoms.
Biologists classify organisms according to their interactions with each other.
Extending their work may include living distinctive form and set of attributes in nature.
The organisms study the environment.
Ecologists are related genetically.
A group of organisms.
Life is found in the air.
There are different types of species in water, land, and the soil.
