What does biochemical study
studies are helpful to investigate information on carbohydrates, proteins, lipids, and nucleic acids.
What does biomedical study
studies deal with providing detailed of information on the chemical components of medicinal plants
What does biophysical study
study is the science of using physical devices to gather biological information at all scales of biological organization (molecular, organismic, and populations).
What does environmental study
study is a multidisciplinary system dealing with the interactions of humans with the environment.
What does bioinformatics study
is a scientific discipline involving computer technology to collect, store, analyze, and disseminate biological data and information (DNA and amino acid sequences).
What does bio geological study
information is the study of the distribution of species along with geographic ecosystems through geological periods.
How does a pregnancy urine test check if a women is pregnant or not
By detecting the amount of human chronic gonadotropin (HCG) produced in the placenta around six to ten days after fertilization
What is computer information technology scanning (CITS) used for?
is a device used for investigating information on diseases or cancerous areas of the human body
What does computer tomography (CT)scan?
is a sophisticated x-ray technology used to take many X-ray pictures of the body and detect and screen a variety of diseases and conditions
What is Positron emission tomography used for?
is an imaging technology device used to check for diseases or information in areas with cancer in the human body. It uses a special dye containing radioactive tracers that is swallowed, inhaled, or injected into an arm vein conditionally. It visualizes and measures changes in metabolic processes and physiological activities (blood flow, chemical composition, and absorption)
_______________and _________________have resulted in the misuse and destruction of our natural environment
-industrialization and subsequent technological advancements
Technology has damaged our world in Two main ways
- through pollution
-the depletion of natural resources.
What does effluent mean
Effluent refers to wastewater or liquid waste that is discharged from a source
_______________,______________ and _____________ cause toxicity and biohazards
- biochemical agents
-pesticide - fertilizer
Animals are sentient creatures that have a
a nervous system, feel painful feelings, emotional stress, and have interests and values.
Researchers reduce unethical treatment of animals through the three Rs which are
- refinement
-replacement
-reduction
What techniques does reduction use
-improving experimental techniques
-sharing information with others
- careful design and analysis
-imaging
What techniques does refinement use
- less invasive techniques
-better housing care
-shorter experiment - imaging
What does replacement use
- using cell cultures
- biosynthesis
- computer simulated models
- using mathimatical models
-human experiment - in vitro experiment
-using fruit flies/worms
