He proved that diseases are caused by microorganisms, developed the first vaccine and provided logical ground knowledge on fermentation and brewing.
Answer:
true
Explanation:
Different bacteria like to grow at different temperatures. Thus, a microbiologist will incubate a particular strain of bacteria at its optimal temperature so that he can study it when it is healthy. By changing the temperature, he can study the bacteria while they are stressed. Organisms that grow best at human body temperature, which is approximately 37 degrees Celsius (98.6 degrees Fahrenheit), are called mesophiles. Those that grow in hot temperatures between 40 to 70 degrees Celsius (104 to 158 degrees Fahrenheit) are called thermophiles. Those that grow at hot temperatures above 80 degrees Celsius are hyperthermophiles. Those that live in very cold conditions are called psychrophiles.
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poorblood from the body into the right atrium of the heart.i As the ventricle contracts, blood leaves the heartthrough the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated
How does blood flow through the heart step by step?
Blood from the body flows:
1. to the superior and inferior vena cava,
2. then to the right atrium.
3. through the tricuspid valve.
4. to the right ventricle.
5. through the pulmonic valve.
6. to the pulmonary artery.
7. to the lungs
Yes, this is true. Duchenne muscular dystrophy is an X linked recessive disorder.
