Sit in front of a heater- what are the options
Hi
Inside your ear there is water this water is detected in your ear and a signal is send to your brains so you know your balanced. If you have an infection. This signal is blocked so you can't feel if you're balanced or not.
Answer: Definition of Selectively Permeable Membranes. All cells are enclosed with a cell membrane. A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport.
A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of <u>evolutionary genetics.</u> The mutation will lead to <u>all the bacteria becoming resistant to the antibiotic.</u><u> </u>
Genetic evolution :
Evolutionary genetics examines the relationship between genetic variation and evolutionary change. As a result of the recent expansion in the availability of whole genome sequence data, large amounts of genetic data are being produced at an increasing rate, making programming an indispensable tool for researchers.
The spread of antibiotic resistance among pathogenic bacteria is a straightforward and elegant example of adaptation through natural selection. Through mutations that alter the biological targets of antibiotics or by obtaining resistance genes from other bacteria, microorganisms can develop resistance to antibiotics.
