Transcript of Ten themes unify the study of life

Biological system:
A biological system is basically a combination of parts formed together to create a complex a complex system. For example a car is a combination of many parts and pieces. Each piece individually is just that one single part but combined together they can create the car or motorized vehicle. The cellular basis of life:
All organisms are made up of cells and most multicellular organisms have cells that are specialized for specific functions. An example would be nerve tissue. The tissue consists of many nerve cells and together they make up a complex network. Form and Function:
How something works is related to its structure. In other words if you needed to screw in a screw you don’t uses a hammer . you need to uses the correct form in order to achieve the correct function. Reproduction and inheritance:
Offspring is in a way are replicas of their parents and grandparents. The child inherits genes from their parents which gives them their unique characteristics that are also known as DNA.
Interactions with the environment:
Every organism in its environment is continuous in its own way. For instance a plant goes through photosynthesis to make its own food and nutrition. The transfer of chemicals between organism and their environment is a key part in any ecosystem.
Energy and life:
We obtain our energy in a chemical form from molecules in our food. Energy travels through an ecosystem in sunlight and in heat; ecosystems convert one form of energy into another. Producers like plants make some of the energy, and consumers like animals eat the food made by the producers. Energy stored in the body is used to carry out life activities.
Your body has a regulated temperature of about 98.6 degrees Fahrenheit. When you do an activity and the temperature of your body rises to higher then your regular temperature your brain signals your body to produce sweat. For example when a dog sticks out its tongue and pants that’s its form of sweating.
Adaptations and evolutions:
Adaptation means an inherited trait that helps the organism’s ability to survive and reproduces in its particular environment. Evolutions mean specifically a generation-to-generation change in proportion different inherited genes in a population
Biology and society:
Recently in the past few years people have been using biology to perform medical procedures, developing pest- resistance crops, and creating wildlife refuges where animals and other species can be protected and studied.
Scientific inquiry:
Chapter 2 involves asking about nature and using observations or experiments to figure out answers to questions.
