Louis Pasteur ForMemRS (/ˈluːi pæˈstɜːr/, French: [lwi pastœʁ]; December 27, 1822 – September 28, 1895) was a French biologist, microbiologist, and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever and created the first vaccines for rabies and anthrax.
His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and is popularly known as the "father of microbiology".[4][5][6]
Pasteur was responsible for disproving the doctrine of spontaneous generation. He performed experiments that showed that, without contamination, microorganisms could not develop. Under the auspices of the French Academy of Sciences, he demonstrated that in sterilized and sealed flasks, nothing ever developed; and, conversely, in sterilized but open flasks, microorganisms could grow.[7] Although Pasteur was not the first to propose the germ theory, his experiments indicated its correctness and convinced most of Europe that it was true.
Today, he is often regarded as one of the fathers of germ theory.[8] Pasteur made significant discoveries in chemistry, most notably on the molecular basis for the asymmetry of certain crystals and racemization. Early in his career, his investigation of tartaric acid resulted in the first resolution of what is now called optical isomers. His work led the way to the current understanding of a fundamental principle in the structure of organic compounds.
He was the director of the Pasteur Institute, established in 1887, until his death, and his body was interred in a vault beneath the institute. Although Pasteur made groundbreaking experiments, his reputation became associated with various controversies. Historical reassessment of his notebook revealed that he practiced deception to overcome his rivals

Describe the location and names of the parts of the pistil.
Describe the location and names of the parts of the stamen.
What were the differences between the Flower A and Flower B?
How were both flowers similar?
Answer: The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg called ovules. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
Explanation:
In science class, Blaine’s teacher puts one glow stick in a cup of hot water and another glow stick in a cup of cold water. She asks the students to think about how the temperature of the water will affect the chemical reaction that occurs inside the glow stick once it is bent and starts to glow.
Which glow stick will be brighter once it is bent? Explain your answer.
Answer:
The glow stick that was in the cup of hot water will be brighter once it is bent. The production of more light is evidence that the chemical reaction in the glow stick is happening faster. The reaction happens faster, because increasing the temperature increases the rate of a chemical reaction.

According to this food web, which of the following organisms do hawks eat?
Snakes and squirrels
Wolves and mushrooms
Grasshoppers and wolves
Squirrels and mushrooms
Answer:
snakes and squirrels
Explanation:
According to this food web, hawks eat the organisms like Snakes and squirrels. Thus, the correct option is A.
What is the Food web?The food web may be defined as the interconnection of a large number of the food chain with one another and forming a web-like pattern.
In a food web, one organism can hold more than one position. In other words, it is a series of branching lines rather than a straight line. The flow of energy is very difficult to calculate in the food web.
Hawks are the tertiary consumers that eat toads, snakes, squirrels, etc. So, hawks are carnivore organisms. Because of being the tertiary consumers, they significantly depend on secondary consumers.
Mushrooms are decomposers. So, options B and D are eliminated. Option C contains grasshoppers that feed on the grass directly. So, they are primary consumers in the food web.
Therefore, according to this food web, hawks eat the organisms like Snakes and squirrels. Thus, the correct option is A.

What are the 2 ways plants use energy?
Answer:
What are the 2 ways plants use energy?
Explanation:
This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. First, the energy from solar radiation is trapped in the plant. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants.
Answer: Plants use solar energy (or energy from the sun) to change water and carbon dioxide into a sugar called glucose. Another source of energy is Chemical energy.
Explanation: Or in short terms. Solar and chemical

In what type of soil would you recommend locating a drinking water well?
Options:
Sand
Gravel
Soil
Clay
Explain why.
Sand is best for the locating a drinking water well, it is free of rocks good for the water well, hence option A is correct.
What is sand?It is a dry, light, warm, and observe to be acidic and low in nutrients. Sandy soils are frequently suggested as light soils due to their high quantity of sand and little clay (clay measures more than sand).
There are four different types of soil:
Sandy soil.Clay Soil.Silt Soil.Loamy Soil.If soil comprises larger proportion of big particles, it is known as sandy soil. If the quantity of fine particles is comparatively higher, then it is named clayey soil. The quantity of large and fine particles is usually the same, then the soil is called loamy.
Therefore, sand is the best for the locating a drinking water well, hence option A is correct.

Base your answer on the passage below
Avian (Bird) Flu
Avian flu virus H5N1 has been a major concern recently. Most humans have not been exposed to this strain of the virus, so they have not produced the necessary protective substances. A vaccine has been developed and is being made in large quantities. However, much more time is needed to manufacture enough vaccine to protect most of the human population of the world.
Most flu virus strains affect the upper respiratory tract, resulting in a runny nose and sore throat. However, the H5N1 virus seems to go deeper into the lungs and causes severe pneumonia, which may be fatal for people infected by this virus.
So far, this virus has not been known to spread directly from one human to another. As long as H5N1 does not change to another strain that can he transferred from one human to another, a worldwide epidemic of the virus probably will not occur.
3.Identify one event that could result in the virus changing to a form able to spread from human to human.
As the virus goes from bird-to-bird and bird-human. The virus may become unstable enough and mutate like crazy. One of those mutations could be like lethality or severity, But more important, human-human spreading.
