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

Smokers are passing down problems to future generations. Men who smoke and drink alcohol could be endangering the health of their future children and grandchildren. Toxic chemicals in cigarettes and alcohol are thought to cause changes in the DNA, which are passed down via the sperm to future generations.
4.Explain how smoking and drinking alcohol by males can affect the development of an embryo.
Answer:
Prenatal exposure to smoking and alcohol increases the risk for Sudden Infant Death Syndrome Physiological changes associated with these exposures are not well studied. Full-term infants were tested within the first 3 days of life.
Explanation:
Answer:
Smoking may also increase a baby's risk of various birth defects, including cleft lip, cleft palate, and clubfoot. Even more frightening is research suggesting that babies whose mothers smoked during pregnancy are more likely to die of sudden infant death syndrome

Answer: microscopes
Similarly the development of microscopes drove, somewhat later in the same century, the discovery of cells; Hooke and van Leuwenhoek, like Galileo, were hands-on developers of their instruments.The discovery of the green fluorescent protein (GFP), increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technical advances that have spurred on many areas of cell biology

What is the other vacuole a paramecium has and what is its purpose?
Answer:
Vacuoles take on specific functions with a paramecium cell. Explanation:
Food vacuoles encapsulate food consumed by the paramecium. They then fuse with organelles called lysosomes, whose enzymes break apart food molecules and conduct a form of digestion.

How does the paramecium release its waste?
Answer:
The paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove.

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.

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 two types of anaerobic respiration? Describe the two in one paragraph.
Answer:
The two main types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.These strategies of respiration occur while the amount of oxygen available is simply too low to guide cardio respiratory.Alcoholic fermentation converts glucose into ethanol. In alcoholic fermentation, glucose is broken down via glycolysis, and two ATP molecules are released in the method. The pyruvic acid molecules produced for the duration of glycolysis destroy down into ethanol and carbon dioxide. In animals, the technique of lactic acid fermentation, further, happens after the glycolysis process. Pyruvic acid is changed into lactic acid, and muscles is damaged down through lactic acid.
Explanation:
The two types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.
Explain anaerobic respiration
Some microbes, including yeast, can ferment alcohol. This procedure transforms glucose into ethanol and carbon dioxide. Through a sequence of biochemical processes, glucose is turned into pyruvate, which is then transformed into ethanol.
On the other hand, lactic acid fermentation takes place in different types of bacteria and human muscle cells. Lactic acid is produced during lactic acid fermentation from glucose. When there is a shortage of oxygen, such during vigorous exercise when muscle cells are unable to receive enough oxygen for aerobic respiration, this process takes place. Although lactic acid fermentation results in an accumulation of lactic acid, which can contribute to muscle discomfort and tiredness, it also helps renew the NAD+ molecules required for glycolysis to proceed.
